How to Improve Shifting and Power Transfer With Your Automatic Transmission

May 10, 2023 by Denver Express Car Care

Your car is made up of thousands of components put together to create several important systems. You couldn’t drive a car without an engine, fuel, suspension, braking, or electrical system. Your car also wouldn’t go without the transmission.

According to a recent CarMax survey, 96 percent of Americans drive automatics. That means fewer people are purchasing manual transmissions, with fewer learning to shift manually. For automakers, it might be easier for production. But it also means fewer people will understand just how vital the transmission job is.

Even with an automatic transmission, there are still things you can do to improve shifting and create a better driving experience.

Why we prefer automatic transmission

In the early days of the automobile, all cars had manual transmissions, which required the driver to manually shift gears using a clutch pedal and a gear shift. However, as cars became more popular and more affordable, the need for easier-to-use and more convenient transmissions became apparent.

How to Improve Shifting and Power Transfer With Your Automatic Transmission

A Canadian engineer named Alfred Horner Munro developed the first automatic transmission in 1921. His design used a fluid coupling instead of a clutch, which allowed the car to shift gears automatically. However, Munro’s design could have been more successful and was never put into production.

In the following years, several other inventors and engineers worked on improving automatic transmissions. One of the most successful was the Hydra-Matic transmission, developed by General Motors in the 1930s. The Hydra-Matic transmission used a combination of fluid couplings and planetary gears to shift gears automatically. It was first introduced in the 1940 Oldsmobile.

Over time, automatic transmissions became more popular among car buyers, and by the 1960s, most cars sold in the United States were equipped with automatic transmissions. There were several reasons for this shift in preference, including:

Automatic transmissions are much easier to use than manual transmissions – push and go!
Automatic transmissions require less effort from the driver, which can be more convenient in heavy traffic or when driving long distances.
Modern automatic transmissions are designed to shift gears at the optimal time, which can improve fuel efficiency compared to manual transmissions.
Some automatic transmissions, such as dual-clutch transmissions, can shift gears faster than a human can, improving the car’s acceleration and overall performance.
Modern automatic transmissions are more reliable than older designs, which were prone to mechanical failure.

While some car enthusiasts still prefer manual transmissions for greater control and driving experience, automatic transmissions have become the more practical and convenient choice for most drivers. In the United States and across the world, automatics are becoming the mainstay.

How an automatic transmission works

An automatic transmission uses a complex system of gears, hydraulics, and electronics to shift gears automatically as the car accelerates and decelerates. It uses:

Torque converter – The torque converter is a fluid coupling that connects the engine to the transmission. It allows the engine to keep running while the car is stopped, and it also multiplies the torque produced by the engine to help the car accelerate.

Planetary gear sets – Inside the transmission are several planetary gear sets, which consist of a sun gear, a planet gear, and a ring gear. The transmission can change the gear ratio between the engine and the wheels by locking or unlocking these gears.

Hydraulic system – The transmission uses a hydraulic system to control the planetary gear sets. A pump in the transmission pressurizes transmission fluid, which is then used to activate hydraulic pistons that engage or disengage the gears.

Valve body – The valve body is a control center for the hydraulic system. It contains several valves that control the flow of fluid to the various parts of the transmission, allowing it to shift gears automatically.

Electronic controls – Modern automatic transmissions also use electronic controls to manage the shifting process. The transmission control module (TCM) uses sensors to monitor the car’s speed, throttle position, and other variables, and it uses this information to determine the optimal time to shift gears.

When the car is in motion, the transmission shifts gears automatically based on the driver’s inputs and the TCM’s commands. When the car needs to accelerate, the transmission shifts to a lower gear to provide more power, and when the car needs to slow down, the transmission shifts to a higher gear to save fuel. The process is seamless and automatic, making it easy and convenient for the driver.

Ways to improve your driving with an automatic transmission

You drive an automatic. You like the convenience. But you also want to enhance your driving experience. What can you do?

Learn to use the additional gears – Modern automatic transmissions come with additional gears, such as “sport mode”, allowing the driver to shift gears manually. Learning to use these additional gears can improve your driving in several ways. For example, “sport mode” can provide a more responsive and engaging driving experience, while “manual mode” can give you more control over the car’s acceleration and deceleration. Take the time to study your owner’s manual and learn how to use these additional gears, and experiment with them to see how they affect your driving.

Maintain engine performance – Your car’s engine performance is essential to the performance of your automatic transmission. If your engine is not running at its best, it can cause your transmission to work harder, leading to damage and decreased fuel efficiency. To maintain engine performance, be sure to follow the recommended maintenance schedule for your car, including regular oil changes, air filter replacements, and spark plug replacements.

Have proper tire alignment – If your tires are not aligned correctly, it can cause uneven wear on the tires, affecting the handling and performance of your car. To ensure proper tire alignment, have your tires checked and aligned regularly by a professional mechanic.

Ensure correct tire size – Using the correct tire size is also crucial to the performance of your automatic transmission. If your tires are too large or too small, it can affect the gear ratios in your transmission, which can cause it to work harder and decrease fuel efficiency. To ensure you’re using the correct tire size, refer to your car’s owner’s manual or consult a professional mechanic.

Properly maintain your transmission – Proper maintenance of your automatic transmission is essential to its performance and longevity. Be sure to follow the recommended maintenance schedule for your car’s transmission, including regular fluid changes and filter replacements. Additionally, check for any signs of transmission problems, such as slipping gears or fluid leaks, and have them repaired promptly to avoid further damage.

What To Know About Refrigerant and Your Vehicle in 2023

May 7, 2023 by Denver Express Car Care

The temperatures are climbing up, up, up! It’s not yet summer, and you’re already cranking up your car’s air conditioner. Is the air conditioner working? Is refrigerant low? What should you know?

Refrigerant, also known as freon, is an important part of your air conditioning system. If it’s low, your A/C won’t operate.

What is refrigerant?

Refrigerant is a substance used in refrigeration systems to transfer heat and provide cooling. In a vehicle, refrigerant is used in the air conditioning system to remove heat from the interior of the car and expel it outside, making the inside of the vehicle cooler and more comfortable for passengers.

You might have heard refrigerant referred to as Freon. Freon is a brand name for a type of refrigerant commonly used in older air conditioning systems. Specifically, it refers to a kind of chlorofluorocarbon (CFC) refrigerant used in the past but has since been phased out due to its harmful environmental impact. CFCs have been found to deplete the ozone layer, which protects the Earth from harmful UV rays.

Nowadays, most vehicles use refrigerants that are much less harmful to the environment, such as hydrofluorocarbons (HFCs) or hydrochlorofluorocarbons (HCFCs). These refrigerants are designed to provide similar cooling performance as Freon, but with much less environmental impact.

What refrigerants are used in today’s cars?

Car manufacturers constantly look for ways to improve their vehicles. When Freon was phased out, designers looked for new ways to do the job more effectively. That’s when different types of automotive refrigerants were developed.

What To Know About Refrigerant and Your Vehicle in 2023

Today’s vehicles typically use one of two refrigerants: R134a and R1234yf. Check your owner’s manual to determine what your car uses – they should never be mixed.

The main difference between the two is their impact on the environment.

R134a has been used in automotive air conditioning systems for many years and is known to have a relatively low impact on the environment. However, it is still a greenhouse gas and can contribute to global warming.

R1234yf is a newer refrigerant developed as a more environmentally friendly alternative to R134a. It has a much lower global warming potential than R134a, meaning it has a much smaller impact on the environment. R1234yf also has a shorter atmospheric lifetime than R134a, which means it breaks down more quickly and has less of a long-term effect on the environment.

However, one potential drawback of R1234yf is that it is a mildly flammable refrigerant, which has raised some safety concerns. To address these concerns, automotive manufacturers have designed new air conditioning systems specifically designed to use R1234yf and minimize potential safety risks.

Overall, both R134a and R1234yf are effective refrigerants for automotive air conditioning systems, but R1234yf is considered more environmentally friendly.

How refrigerant works inside a vehicle

Refrigerant works by absorbing heat from the car’s interior and then releasing that heat to the outside environment.

The refrigerant circulates through the air conditioning system in a closed loop, starting in the compressor. The compressor pressurizes the refrigerant and pumps it through the system, where it passes through the condenser. The condenser is located at the front of the vehicle. It’s designed to dissipate heat, allowing the refrigerant to release the heat it has absorbed from the interior of the car.

After passing through the condenser, the refrigerant enters the expansion valve or orifice tube. This component is designed to regulate the flow of refrigerant into the evaporator, which is located inside the vehicle’s cabin. As the refrigerant flows through the evaporator, it absorbs heat from the air inside the car and cools it down.

The cooled air is then blown into the interior of the vehicle by the air conditioning system’s blower fan, providing cool and comfortable air for the passengers.

Once the refrigerant has absorbed heat from the interior of the car, it circulates back to the compressor to repeat the process. The cycle continues as long as the air conditioning system is turned on.

How do you know if the refrigerant is low?

Several signs can indicate that the refrigerant level in your vehicle’s air conditioning system is low. These include:

Blowing warm air from the vents

If your air conditioning system is blowing warm air instead of cold, this can be a sign that the refrigerant level is low. Refrigerant is responsible for absorbing heat from the car’s interior and releasing it outside, so if there isn’t enough refrigerant in the system, it won’t be able to cool the air effectively.

Rapid cycling of compressor clutch

The compressor clutch is the component that engages and disengages the compressor in the air conditioning system. If the refrigerant level is low, the compressor may start to cycle rapidly on and off as it struggles to maintain the correct pressure in the system.

A/C warning light

Many modern vehicles are equipped with an A/C warning light on the dashboard that will illuminate if there is a problem with the air conditioning system. If the refrigerant level is low, this can trigger the warning light to come on.

Refrigerant leaks

If there is a leak in the air conditioning system, this can cause the refrigerant level to drop over time. Signs of a refrigerant leak can include hissing or bubbling noises coming from the system, oily residue around the A/C components, or a noticeable decrease in cooling performance over time.

If you suspect that the refrigerant level in your vehicle’s air conditioning system is low, it’s crucial to have the system inspected by a qualified mechanic. Low refrigerant levels can cause damage to the compressor and other components in the system, so it’s essential to address the issue as soon as possible.

The Importance of Addressing Check Engine Lights Immediately

April 28, 2023 by Denver Express Car Care

You start up your car. The dashboard lights illuminate. One of them stays on. Now what?

Check engine lights can signal you have a major vehicle issue. It can also be the sign of something minor – something you’ll have to fix eventually, but won’t impact your current drive.

Minor issues could include:

A bad oxygen sensor
Faulty spark plug wires
A loose fuel cap
Faulty mass airflow sensor

These are drivable issues. You should fix the problem or schedule an appointment with your mechanic at your earliest convenience.

Major issues could include:

A coolant system malfunction
A fuel injector problem
A faulty catalytic converter
Engine failure

These are all major issues. Continued driving will only further impact your car, possibly to the point of it ceasing altogether.

The Importance of Addressing Check Engine Lights Immediately

But how do you know the difference? Because a check engine light can mean so many things, how do you know what to do?

How to determine if it’s safe to drive with the check engine light on

When any light illuminates on your dashboard, it’s a sign of a potential problem. Should you turn the car off immediately? Do you have time to drive to your mechanic? Can it wait several days until you can schedule an appointment? There are three things you can do.

1. Pull over and turn off the engine as soon as possible. This may reset the icons and cause the check engine light to turn off. If it still illuminates, do any other icons light up? For example, a low oil pressure light with the check engine light might signal overheating issues. Have you noticed it in the way your car drives? Is there smoke coming up from the hood of the vehicle? This is your time to become aware of what your vehicle is trying to tell you.

2. Check your gas cap. If you’ve recently refueled, it’s time to pull over and adjust your gas cap to ensure it’s tightly in place. This is a common problem, and the check engine light can take several restarts to reset. This light comes on whenever it detects a leak in the emissions system, which can occur if the gas cap isn’t tightly sealed. Be aware that newer models occasionally will also have a gas cap indicator on the dashboard.

3. Reduce speed and load. The check engine light may come on as you drive in and out of the mountains. We see this a lot here in Colorado. The check engine light warns you to lower your speed and take it easy on the engine. If you’re towing anything or have a heavy low, you should try and unload it as soon as possible to avoid potential repairs. You should also have it quickly inspected to find out what maintenance items should be fixed.

Is it safe to drive when the check engine light is on?

We hear you – even with the above steps in mind, the check engine light seems like a good indicator of something wrong with your vehicle.

And we agree – why chance it? Your engine is one of the most expensive components of your vehicle. Engine failure can run well into the thousands of dollars for repair. It’s easier to assume the worst and get your car inspected quickly as soon as you discover the check engine light stays illuminated.

The check engine light is an indicator that there may be a problem with your vehicle’s engine or emissions system. The light could indicate something as simple as a loose gas cap or something more severe as a malfunctioning sensor or catalytic converter.

If the light is flashing, it usually means a more severe problem needs immediate attention. In newer cars, your check engine light may have two colors – yellow and red – with the red light indicating a more severe problem. Continuing to drive with a flashing or red check engine light could cause damage to your engine or emissions system and even result in your vehicle stalling or not starting.

It is best to have your vehicle inspected by a qualified mechanic as soon as possible to determine the cause of the check engine light and address any issues before they become more serious and potentially expensive to repair.

A brief summary of check engine light potential problems

If your check engine light is on, it’s probably one of these things:

Oxygen sensor failure – The oxygen sensor measures the amount of oxygen in your vehicle’s exhaust. If it fails, it can cause your car to run less efficiently and potentially damage your catalytic converter.

Loose gas cap – A loose or missing gas cap can cause fuel vapors to leak out of your vehicle’s fuel system and cause your check engine light to turn on.

Catalytic converter failure – A faulty catalytic converter can cause your vehicle to run poorly and potentially damage other components of your vehicle’s emissions system.

Spark plug issues – Worn spark plugs can cause the engine to misfire or run poorly, triggering the check engine light.

Mass airflow sensor failure – Mass airflow sensor failure can cause your engine to run less efficiently and potentially stall or not start.

Vacuum leak – A cracked or loose connection in one of the hoses that control the air and fuel mixture in your engine can cause your engine to run poorly and trigger the check engine light.

Exhaust gas recirculation valve failure – Exhaust gas recirculation (EGR) valve failure can change the emissions system functionality, which can cause your engine to run poorly and potentially damage other components of your vehicle’s emissions system.

Dead battery – A weak or dead battery can cause the check engine light to turn on.

Is your check engine light on?

You might think, “I don’t have time,” or “It’s probably not that big of a deal.” It is.

Your check engine light is one of the most important dashboard lights you should keep an eye out for.

If yours is illuminated, schedule an appointment today. We’ll have you back on the road quickly.

All About Timing Belts: What They Do and When to Replace Them

April 14, 2023 by Denver Express Car Care

Cars have more than 10,000 parts ensuring they stay operational for many years.

Some components you understand you’ll have to replace from time to time. You replace motor oil, windshield wipers, and tires on a routine.

But what about a timing belt? (Sometimes referred to as a timing chain.) How much do you know about timing belts? Or what the maintenance schedule looks like?

The more you know, the better prepared you’ll be to recognize the warning signs of a timing belt failing, and what you should do along the way.

What is a timing belt?

Every internal combustion engine has a timing belt. It synchronizes the rotation of the crankshaft and the camshaft(s), ensuring that the engine’s valves open and close properly during the engine’s operation.

The timing belt is typically made of rubber with high-tensile fibers, and it is driven by the crankshaft and wraps around the camshaft(s), keeping them synchronized with the crankshaft.

Timing belts are crucial components of an engine, as they ensure that the valves open and close at the correct time. This prevents collisions between the valves and the pistons.

All About Timing Belts: What They Do and When to Replace Them

If the timing belt breaks or slips, the engine may stop working or suffer serious damage, so following the manufacturer’s recommended maintenance schedule to replace the timing belt is essential.

What function does the timing belt play in a car’s operation?

The timing belt plays a crucial role in a car’s operation by synchronizing the rotation of the engine’s camshaft(s) and crankshaft. The camshaft(s) control the opening and closing of the engine’s valves, while the crankshaft controls the movement of the pistons.

The timing belt ensures that the camshaft(s) and crankshaft are in the correct position, so that the valves open and close at the right time with the movement of the pistons. This is important because if the valves are not properly timed, they can collide with the pistons, causing severe damage to the engine.

Regular maintenance, including replacement of the timing belt according to the manufacturer’s recommendations, is essential to prevent potential damage to the engine and ensure reliable performance.

Signs a timing belt is failing

Luckily, a timing belt rarely fails without warning signs of a potential problem. Listen to your car – is it making noises? Take a whiff – do you smell something that’s not quite right? Your vehicle provides lots of guidance – if you pay attention.

Manufacturers recommend replacing the timing belt every 30,000 to 120,000 miles, depending on the make and model. Manufacturers base this engine performance and driving conditions, which change in every situation. Start by checking your owner’s manual. Then pay attention to your car, especially if you start to notice:

Engine misfires – A worn or damaged timing belt can cause the engine to misfire or run erratically, leading to poor performance and reduced power.

Ticking noise from the engine – A ticking noise from the engine can indicate that the timing belt is loose or damaged and is not properly controlling the opening and closing of the valves.

Difficulty starting the engine – A worn timing belt can cause the engine to struggle to start or not start. This is because the belt may have stretched, causing the engine to be out of sync.

Oil leaking from the engine – A damaged timing belt can cause oil to leak from the engine, which can be a sign that the timing belt needs to be replaced.

Visible wear or damage – It is time to replace it if you can see signs of wear or damage to the timing belt, such as cracks, missing teeth, or fraying.

When should you replace a timing belt?

The timing belt is a critical component in a car’s engine, and it is essential to replace it before it fails. The manufacturer’s recommended replacement interval for the timing belt varies depending on the make and model of the vehicle. It can range from 30,000 to 120,000 miles or 5 to 10 years, whichever comes first. It is essential to refer to your car’s owner’s manual to determine your vehicle’s recommended replacement interval.

It is generally recommended to replace the timing belt as a preventative maintenance measure before it reaches its recommended replacement interval. This is because a failed timing belt can cause severe damage to the engine, resulting in expensive repairs.

If you notice any signs of a failing timing belt from above, you should have it inspected by a qualified mechanic as soon as possible. Additionally, if you purchase a used car and do not know the service history of the timing belt, it is recommended to have it replaced as a precautionary measure.

Should you replace your timing belt yourself?

In most cases, the answer is: No. The timing belt is complicated to replace and is often in a place that makes it difficult to service.

Special tools are often needed to install a timing belt correctly. Plus, other parts may need replacement while installing a new timing belt. Aligning the camshaft gears with the crankshaft gear should follow the manufacturer’s specs. Even if a gear is one “tooth” off, it has the risk of running rough.

And that could be detrimental to the overall operation of your vehicle.

When the pros replace the timing belt, they often replace things like the drive belts, water pump, change the motor oil and filter, and flush the cooling system. It all depends on the timing belt’s location and what makes the most sense for your vehicle.

What condition is your timing belt in?

Tips for Maintaining Your Car’s Air Conditioning System

April 4, 2023 by Denver Express Car Care

The seasons are changing. Summer is a short time away.

Before you know it, the temperatures will be climbing up, up, up.

Will your car’s air conditioning system be ready for the challenge? Performing a little TLC now will help maintain your car’s air conditioning system no matter what the weather is like outside.

Your car’s cabin can reach as much as 140 degrees on the hottest days of the year. If you want your AC system to work no matter what the thermometer reads, you’ll have to add a maintenance visit to your regular routine.

Understanding a car’s air conditioning system

The air conditioning system in a car is responsible for cooling and dehumidifying the air inside the cabin. The basic components of a car’s AC system include:

The compressor is the heart of the AC system. It is driven by a belt from the engine, which compresses the refrigerant gas and circulates it through the system.

The condenser is located at the front of the car and releases heat from the compressed refrigerant gas. It looks like a small radiator and has fins to dissipate heat.

The evaporator is inside the car’s cabin, typically behind the dashboard. It absorbs the heat from the air inside the vehicle, causing the refrigerant to evaporate and turn into a gas.

The expansion valve or orifice tube is a small component between the evaporator and the compressor. It controls the flow of refrigerant into the evaporator.

The air conditioning system compresses the refrigerant gas in the compressor and then circulates it through the system. As the compressed gas moves through the condenser, it releases heat and becomes a high-pressure liquid. The liquid then flows through the expansion valve or orifice tube, which lowers its pressure and causes it to evaporate as it passes through the evaporator. The evaporating fluid absorbs the heat from the air inside the cabin, which is then blown out through the car’s vents.

Tips for Maintaining Your Car's Air Conditioning System

The system is closed and continuously circulates the refrigerant gas, which means that a low refrigerant level or a malfunctioning component can reduce cooling efficiency or cause a system failure. Regular maintenance and servicing can ensure the proper functioning of the AC system.

How do you know if your car’s air conditioner is failing?

Several signs can indicate a failing AC system in a car. The most common include:

Reduced cooling performance – If your car’s AC system is no longer cooling the cabin as effectively as it used to, this can be a sign of a problem. The air from the vents may feel warm or not as cool as it should be.

Strange noises – Unusual sounds from the AC system, such as grinding, hissing, or rattling, can indicate a problem. A malfunctioning compressor or other components can cause these noises.

Foul odors – If you notice a bad or musty smell from the AC system, this can be a sign of mold or bacteria growth in the evaporator. This can also cause health problems if left untreated.

Water leaks – If you see water leaking from the AC system, this can indicate a clogged drain tube or a malfunctioning evaporator.

AC system not turning on – If the AC system fails to turn on, this can be caused by a blown fuse, a faulty compressor, or an electrical problem.

If you notice any of these signs, it is vital to have the AC system checked by a qualified mechanic. Ignoring these issues can lead to further damage to the AC system and higher repair costs.

What regular maintenance items should you do to keep the air conditioner operating well?

Nothing is worse than being surprised with an air conditioner that suddenly doesn’t seem to work on the hottest day of the year. To avoid this, stick with a regular maintenance schedule to ensure its proper functioning and prevent issues from arising.

Change the cabin air filter – The cabin air filter helps prevent dust, pollen, and other debris from entering the cabin and clogging the AC system. A dirty or clogged cabin air filter can reduce the airflow and cooling efficiency of the AC system. Changing the cabin air filter every 12,000 to 15,000 miles or once a year is recommended.

Inspect the belts and hoses – The belts and hoses in the AC system can wear out over time and develop cracks or leaks. Regular inspection can help detect any issues before they cause significant problems.

Check the refrigerant level – The refrigerant is the substance that cools the air in the AC system. A low refrigerant level can reduce the cooling performance and cause the compressor to overwork. It is recommended to check the refrigerant level every 12,000 to 24,000 miles or every two years.

Clean the condenser – The condenser can become clogged with dirt, debris, and bugs, reducing its ability to release heat from the refrigerant. Regular cleaning with a soft brush or compressed air can help maintain efficiency.

Run the AC system regularly – Running the AC system regularly can help keep the system lubricated and prevent the seals from drying out.

Have the AC system serviced regularly – Have the AC system inspected and serviced by a qualified mechanic every two years or as the manufacturer recommends.

Is your air conditioner ready for the summer season?

Regular maintenance and servicing of the AC system can help prevent any of these problems from occurring in the first place. It’s the best way to ensure your vehicle is ready for whatever Colorado weather dishes out.

When was the last time you had your air conditioner inspected?

Get ready for the summer – book your maintenance visit now.

Understanding the Ins and Outs of Car Engine Repair

March 28, 2023 by Denver Express Car Care

At the center of your vehicle, the very heart of what makes your car operate, is the engine. Without an engine, your car would cease to go.

A car engine has dozens of pieces, including:

Engine block
Combustion chamber
Cylinder head
Pistons
Crankshaft
Camshaft
Timing belt
Valves
Fuel injectors
Spark plugs
Oil pan
Manifold
Piston rings
Flywheel

While it may seem easy to you – turn the key, and it works, a car engine is a complex machine designed to convert energy into mechanical energy, allowing the entire vehicle to function.

When it works well, it’s one of the most dynamic inventions we live with each day. However, if one of those components goes bad at any point, it can lead to problems.

Car engine repair keeps your engine running smoothly for the life of your vehicle.

Understanding the Ins and Outs of Car Engine Repair

How a car engine works

A car engine is an intricate machine that converts fuel into mechanical power. Without this, your vehicle would never move. It consists of several parts that work together in a complex sequence to keep the car running.

Most common car engines use an internal combustion engine. It burns fuel inside a cylinder to create power. This engine can run on gasoline, diesel, or other fuels. The motor contains several cylinders, each with a piston that moves up and down.

The intake stroke is the first step in the engine cycle. The piston moves down, which creates a vacuum in the cylinder. This vacuum pulls air into the engine through an intake valve. Some engines also have a turbocharger or supercharger that compresses the air, which increases the engine’s power output.

In the compression stroke, the piston moves back up and compresses the air and fuel mixture. This mixture is highly combustible and needs to be compressed to increase the pressure and temperature inside the cylinder. The compression ratio is critical in determining the engine’s efficiency and power output.

In the ignition stroke, the spark plug fires, which ignites the air and fuel mixture. This explosion creates a rapid expansion of gasses, which pushes the piston down. The energy released by the explosion powers the engine.

In the final exhaust stroke, the piston moves back up, forcing the spent gasses out of the cylinder through an exhaust valve. The gasses are routed through the exhaust system and released into the atmosphere.

The valvetrain is the system that controls the intake and exhaust valves. It is responsible for opening and closing the valves at the appropriate times. The camshaft, driven by the crankshaft, controls the valve timing. The camshaft has lobes that push on the lifters, opening and closing the valves.

The fuel system is responsible for delivering fuel to the engine. The most common fuel system type is a fuel injection system, where the fuel is pressurized and sprayed into the engine through a nozzle. The engine’s computer controls the amount of fuel injected into the engine, which monitors several sensors to determine the optimal fuel-air mixture.

The cooling system is essential for preventing the engine from overheating. The engine generates a lot of heat, which can damage the internal components. The cooling system circulates coolant through the engine to absorb the heat and transfer it to the radiator. The radiator dissipates the heat into the atmosphere.

Keeping your car engine running smoothly

Now that you have a deeper understanding of how a car engine works, it may be easier to understand how maintenance plays into keeping it running smoothly. It’s an intricate machine that works well when everything is in good operating condition but can quickly fail when something goes wrong.

Car manufacturers and repair shops all agree you should keep certain maintenance items on your calendar throughout the year. They include:

Regular Oil Changes – Regular oil changes are one of a car engine’s most critical maintenance tasks. The oil lubricates the engine’s moving parts and helps to keep it clean. Over time, oil breaks down, and its ability to lubricate the engine diminishes. Changing the oil and filter every 3,000 to 5,000 miles is recommended.

Air Filter Replacement – The engine’s air filter prevents dirt and debris from entering the engine. Over time, the filter can become clogged, reducing airflow and decreasing performance. A dirty air filter should be replaced every 12,000 to 15,000 miles.

Spark Plug Replacement – Spark plugs ignite the air-fuel mixture in the engine cylinders. Worn or dirty spark plugs can cause misfires, reduced performance, and reduced fuel economy. Replace spark plugs every 30,000 to 100,000 miles, depending on the plug type and the vehicle’s use.

Coolant System Flushing – The engine’s coolant system helps to regulate the engine’s temperature. Over time, coolant can become contaminated and lose its effectiveness. Flushing the coolant system every 30,000 miles or every 2 to 3 years helps to prevent overheating and engine damage.

Timing Belt Replacement – The timing belt connects the crankshaft and camshaft and keeps the engine’s valves and pistons in sync. A broken timing belt can cause severe engine damage. Replace the timing belt every 60,000 to 100,000 miles, depending on the vehicle’s manufacturer’s recommendation. Don’t wait until it breaks; keep this on your to-do list and replace it before it wears down.

Regular Tune-Ups – Regular tune-ups can help keep the engine running smoothly and efficiently. A typical tune-up includes replacing spark plugs, inspecting ignition wires, and checking the fuel and air filters.

Proper Driving Habits – It’s not just regular maintenance that keeps your engine in good working condition. Proper driving habits, such as avoiding hard acceleration and deceleration and maintaining a steady speed, can help reduce engine wear and tear.

What condition is your engine in?

It doesn’t take a lot of work to keep your car’s engine running smoothly. Instead, it takes regular inspections and periodic maintenance.

The Exhaust System: How It Works and Why It Matters

March 24, 2023 by Denver Express Car Care

Your car’s exhaust system has an important job. It moves burnt air/fuel mixture out of the engine. Without a working exhaust system, you would drive a noisy car. You would also smell the fumes inside your car.

Have a performance issue? It may stem from the exhaust system. The more you learn about it, the better you’ll be at maintaining it.

How the exhaust system works on a vehicle

The exhaust system is a vital component of a vehicle, responsible for carrying away the harmful byproducts of the engine’s combustion process.

The exhaust system is designed to remove the waste gasses produced during the engine’s combustion process and redirect them out of the vehicle. When the fuel and air mixture in the engine’s combustion chamber is ignited, it produces gasses, including carbon dioxide, nitrogen oxides, and unburned hydrocarbons. If these gasses remained in the engine’s cylinders, they would cause damage and decrease efficiency. The exhaust system removes them and redirects them out of the vehicle.

The exhaust system comprises several components that work together to achieve the basic function. These include:

The Exhaust System: How It Works and Why It Matters

Exhaust Manifold – This exhaust manifold connects the engine’s cylinders to the exhaust pipe. The exhaust manifold collects the waste gasses produced by the engine’s combustion process and directs them to the exhaust pipe.

Exhaust Pipe – The long metal tube carries the waste gasses from the engine’s cylinders to the muffler. It is usually made of steel and is designed to withstand high temperatures and corrosive exhaust gasses.

Catalytic Converter – The catalytic converter is responsible for reducing the emissions of harmful gasses. It converts the gasses into less harmful ones, such as carbon dioxide, water vapor, and nitrogen.

Muffler – The muffler reduces the noise produced by the engine. It creates a series of chambers that absorb the sound waves the engine’s combustion process produces.

Exhaust Tip – The exhaust tip is the visible part of the exhaust system and is usually made of chrome or stainless steel. It is designed to give the vehicle a sporty look and protect the exhaust pipe from damage.

The exhaust system works in a series of stages. In the first stage, the exhaust manifold collects waste gasses from the engine’s cylinders. These gasses are directed to the exhaust pipe, which carries them to the catalytic converter.

The catalytic converter converts harmful gasses into less harmful ones through a chemical reaction. The gasses pass over a surface coated with precious metals such as platinum, palladium, and rhodium, which cause a chemical reaction that converts them into less harmful ones.

From the catalytic converter, the gasses pass through the muffler, which reduces the noise produced by the engine’s combustion process.

Finally, they exit through the exhaust tip at the back of the vehicle.

Why an exhaust system is important

While it may seem obvious, an exhaust system is important for a variety of reasons. The exhaust system plays a crucial role in the engine’s function and in ensuring the safety of passengers and the environment.

It removes harmful gasses – The exhaust system’s primary function is to remove the harmful gasses produced during the engine’s combustion process. These gasses include carbon monoxide, nitrogen oxides, and hydrocarbons, which can be toxic and dangerous to the passengers if they accumulate in the cabin. The exhaust system redirects these gasses out of the vehicle, making it safer to drive.

It improves engine performance – The exhaust system also helps improve the engine’s performance by providing a way to expel waste gasses quickly and efficiently. If the exhaust system is not functioning correctly, it can build up pressure in the engine, leading to decreased performance and fuel efficiency.

It reduces noise – The exhaust system also plays a vital role in reducing engine noise. The muffler is specifically designed to dampen the sound waves the engine’s combustion process produces. Without the muffler, the noise made by the engine would be much louder and more unpleasant.

Environmentally friendly – The exhaust system is also essential for protecting the environment by reducing the engine’s harmful emissions. The catalytic converter helps convert the harmful gasses the engine produces into less harmful ones. This helps reduce the vehicle’s carbon footprint and makes it more environmentally friendly.

It keeps your car in compliance with regulations – Specific regulations mandate using an exhaust system on vehicles to reduce harmful emissions. Failure to comply with these regulations can lead to fines and other legal consequences.

What can you do to keep your car’s exhaust system in good working condition

Properly maintaining your car’s exhaust system is essential to keep it in good working condition. What can you do to ensure it remains in good shape:

Schedule regular inspections – Inspect your exhaust system regularly, ideally every 12 months or every 15,000 miles, to identify any potential issues before they become bigger problems.

Check for leaks – If you hear a loud or unusual noise coming from your car’s exhaust system, it could be a sign of a leak. Check for any visible cracks, holes, or rust on the pipes and muffler, and have them repaired or replaced as soon as possible.

Replace worn-out parts – Over time, parts of your exhaust system, such as the muffler, catalytic converter, or oxygen sensor, can wear out and need replacing. Replace these parts promptly when required.

Avoid driving over rough terrain – Driving on uneven terrain or hitting speed bumps and potholes can cause damage to your car’s exhaust system. Avoid driving on rough terrain as much as possible.

Use the right fuel – Using the wrong type of fuel or poor quality gasoline can build-up of harmful residues that can damage your car’s exhaust system. Always use the type of fuel recommended by your car manufacturer and buy from reputable gas stations.

Keep your engine tuned – A poorly tuned engine can produce more exhaust gasses, putting more stress on your exhaust system. Regularly tune your engine to ensure it runs efficiently and reduces emissions.

Is your car’s exhaust system in good working condition?

Regular inspections, prompt repairs, and proper maintenance are essential to keep your car’s exhaust system in good working condition. Following the tips above can help prevent damage and prolong the life of your car’s exhaust system.
