EGR Valve Guides

The Exhaust Gas Recirculation (EGR) Valve is an integral part of a vehicle's emission control system or EGR System. It controls the engine's emission of nitrous oxides by reducing combustion temperature. Nitrous oxide, also called laughing gas for its euphoric effects, is formed when the fuel is burning at over 2,500 degrees Fahrenheit. At this combustion temperature, nitrogen in the air mix with other gases to form this gas which is capable of altering a person's bone marrow structure in only 3-4 hours of exposure to it.
When released into the atmosphere, nitrous oxide reacts with oxygen and becomes nitrogen dioxide. The latter in turn becomes smog when it comes into contact with hydrocarbons.
The EGR valve first appeared in automobiles in 1972 to counter this phenomenon. EGR valves basically do this by sending some of the exhaust gas through the intake manifold back into the cylinders. Because exhaust gas most often doesn't burn, it stays and takes up space in the combustion chamber and lowers the temperature there. Older vehicles used to have mechanical engine EGR valves, but the newly manufactured ones have electronic EGR valves.
However, the function of EGR valves remains the same, whether they be mechanical or electronic. An EGR system usually doesn't require regular maintenance, but it should nevertheless be checked so as to ensure that you are always complying with emission standards. A malfunctioning EGR valve could also damage your engine if not repaired right away.

Important Facts You Need to Know About EGR Valve

Want to have better fuel efficiency for your ride? You don't need any magic to do it, because all it takes is a quality EGR valve.
Help your car engine, save the world/ Okay, that line might sound exaggerated, but it really does make sense. In a little way, you can do something positive for our environment with a properly working Exhaust Gas Recirculating (EGR) Valve in your engine.
tems of a vehicle. It works by sucking some of the exhaust to the intake manifold and back into the combustion chamber. The exhaust gas then runs through the combustion again where traces of unburned fuel can now be used up. Aside from that, this valve enables your vehicle to burn fuel more effectively because exhaust gas is warmer than the air from the air intake. Warmer gas won't make the engine work harder to heat it up, thus making combustion easier. This part therefore plays a very important role by reducing unwanted engine emissions while, at the same time, facilitating a more complete burn of fuel.
When this valve acts up, this may result in an inefficient combustion and vacuum leak. And since the fuel isn't burned efficiently, this may lead to more fuel consumption. So when that happens, make sure to have your EGR valve cleaned and possibly replaced. After all, wouldn't you want your car to perform well and help save the world at the same time?

EGR Valve: Just the Facts

Despite laws enforcing the mandatory use of automotive emission-control devices, automobiles are still among the top contributors of air pollution. To reduce your carbon footprint, one thing you can easily do is keep your vehicle's exhaust gas recirculation (EGR) valve in good shape. This valve sends a small, metered amount of exhaust gases back into the engine's cylinders, effectively lowering combustion temperature. And a lower combustion temperature, in turn, is essential in preventing the production of nitrogen oxide. This compound, when mixed with various elements in the atmosphere, forms smog. So just by making sure your vehicle's EGR valve works reliably, you can count on your vehicle emitting a lower amount of ecologically harmful gases. You get to do your share for the environment, too. If you're looking to get a new EGR valve for your vehicle, trust no one but CarParts.com. We can give you the best EGR valves in the market, at the lowest prices online.

Choosing the Right EGR Valve for Your Car

The EGR or exhaust gas recirculation valve was first used in vehicles in the 1970s. It was one of the first ever known forms of green technological innovations that car manufacturers applied in their vehicles. The fundamental function of an EGR valve is to reduce nitrogen oxide emissions, which is very detrimental to health. When combined with moisture and sunlight, these harmful gases turn into smog.

If you're shopping for a new EGR valve, you need to consider several factors in order to make the right choice. First off, you need to know the major types of EGR valve. Basically, all these valves function the same way, but each type has a unique assembly of parts like the pintle or the opening and the diaphragm

.

Types of EGR valve

Single diaphragm EGR valve - This is the oldest type of EGR valve. This type is operated by a vacuum, a diaphragm, and the opening. The vacuum directs the flow of pressure to the diaphragm. At a certain temperature, the diaphragm would prompt the valve to open to let some exhaust gas in to lower the temperature in the combustion engine.

Positive back pressure EGR valve - There is usually a "P" stamped on the part code of the valve of this type. In this valve, the exhaust gases freely flow in the pintle shaft. The pressure of these gases controls the movement of the shaft and allows the air to flow inside the engine.

Negative back pressure EGR valve - This type looks very similar to the positive back pressure type, though you can recognize this by the "N" stamped on it. This type is controlled by two things: engine vacuum, which creates back pressure, and impulses, which regulates gas flow into the engine.

Other factors you should consider

Once you have figured out the right EGR valve type for your ride, you need to check on the quality, brand, and price. Quality and brand go hand in hand since well-known labels are known for their durable products and reliable warranties. As for price, it's best to take a look at what various retailers have to offer and compare rates. Don't forget to check if what you're buying already includes all the essential mounting hardware such as gaskets, bolts, and hose connectors. You'd want a EGR Valve Replacement that's easy to install especially if you are planning to do it all on your own.

How to Replace an EGR Valve

It's easy to tell if your car is having problems with its EGR valve. In most cases, there are two scenarios. When the valve is stuck open, it causes leak in the vacuum that often results in low combustion, and engine stall. This is because the engine is full of exhaust gases that oxygen cannot penetrate inside to initiate combustion. The other problem is when the valve is stuck closed. The level of nitrogen oxide continues to rise because it cannot escape through the exhaust pipe. It causes spark knock or a disruption in engine timing. Either of these two can give you a hard time driving your car so it's better to change the EGR valve in your car ASAP.

Replacing the EGR valve is very easy! Get your tools ready and begin.

Difficulty Level: Easy

Duration: 20 minutes

Tools:

  • Socket set
  • Phillips screwdriver
  • Wrench

Follow these steps:

Step 1: Refer to your vehicle owner's manual to locate the EGR valve. The location may be different depending on the type and model of the car.

Step 2: Disconnect your car's battery.

Step 3: Disconnect the intake hose, the vacuum hose, and all the wirings attached to the EGR valve. You can use the screwdriver to remove them.

Step 4: Unscrew the bolts that hold the valve to the car's engine. Use the socket wrench to remove the valve from the EGR tube. If you see that there are holes in the valve itself, you definitely need to replace it. If there are no holes, cleaning the valve with carburetor cleaner, gasket scraper and small drill bit will do the trick.

Step 5: If replacement is necessary, get the new one and insert it to where you've taken out the old one. Put back all the wires, hoses, and bolts that you removed.

Step 6: It's time to reconnect the battery. A test drive is important if you want to see if everything is working well.

It’s no secret that internal combustion engines are not very good for the environment. Combustion produces harmful gas molecules, such as nitrogen oxides and unburnt hydrocarbons, as byproducts of burning air and gasoline. These binary and organic compounds exit the engine through the car’s exhaust system and are extremely harmful to the environment.

To neutralize the toxic elements in exhaust gases, various emission control systems were invented. Among the most popular ones aside from the catalytic converter and the air injection system is the exhaust gas recirculation (EGR) valve. But before you focus on the EGR valve, you have to learn how an EGR system works first. 

How does an EGR system work?

EGR systems divert a measured amount of exhaust gases into the intake tract depending on the engine’s operating conditions. The idea is to reduce the chances of nitrogen oxide (NOx) formation by diluting the air-fuel mixture and by reducing peak combustion temperature. The production of NOx occurs when there’s an excessive amount of oxygen molecules inside the chamber during combustion. This usually happens when the engine is operating in partial load conditions, such as when the vehicle is idling or running at low speeds.

In partial load conditions, the engine operates with less power and the supply of fuel in the chambers is decreased. The reduction in fuel supply could result in an excessive amount of oxygen molecules in the combustion chamber. Some of these oxygen molecules won’t be utilized and will instead bond with the nitrogen molecules present in the mixture and create NOx gases. So why does the system need to pump in exhaust gases back into the chamber? That’s because exhaust gases don’t support combustion and won’t burn any further because they don’t contain oxygen molecules anymore.

Since burned exhaust gases don’t affect combustion, mixing them with fresh air could lessen the amount of oxygen inside the chamber, allowing the mixture to combust properly. With optimum air-fuel ratio, no excess oxygen will bond with nitrogen and no nitrogen oxide will be produced. The EGR system has a valve that controls the amount of exhaust gases entering the chamber called the EGR valve.

What is an EGR valve?

The exhaust gas recirculation valve serves as the gateway that opens and closes to control the flow of exhaust gases returning into the combustion chamber. There are different EGR valve designs but all of them function the same. An EGR valve primarily consists of large and small springs, a vacuum port, and a piston. The large spring holds the valve closed while the vacuum port causes the piston to retract and open the valve.

What does an EGR valve do?

The EGR valve reduces the amount of NOx produced when the air-fuel ratio is compromised. It is responsible for determining how much exhaust gas is needed by analyzing the engine’s load condition. Simply put, the opening and closing of the EGR valve vary depending on the engine’s load conditions. At lower speeds or when idling (partial/low load conditions), the valve opens wide to allow more exhaust gases into the chamber. When the vehicle reaches high speeds (full/high load conditions), the EGR valve shuts to allow more fresh air into the intake tract.

Older vehicles used to have mechanical engine EGR valves, but the newly manufactured ones have electronic EGR valves.

Types of EGR valves

There are two main types of EGR valves: the conventional vacuum diaphragm type and the modern electrically operated type. Here’s a closer look at the two.

Vacuum Diaphragm type

Vacuum diaphragm EGR valves utilize a spring-loaded diaphragm and a vacuum port. There are three styles of vacuum diaphragm EGR valves, which are the single-diaphragm valve, the negative back pressure valve, and the positive back pressure valve.

Single-Diaphragm valve

A single-diaphragm EGR valve consists of a single diaphragm that seals the vacuum chamber shut. The diaphragm opens and closes a pintle, which is a tapered valve, with the help of the vacuum port. When the vacuum is applied to the valve’s chamber, the diaphragm presses against the spring and opens the valve. Spring pressure then closes the valve once the vacuum is released.

Negative Backpressure valve

Unlike single-diaphragm valves, negative backpressure EGR valves have two diaphragms. The main diaphragm, which is attached to the top spring, is connected to a pintle while the second diaphragm connects through a hole in the pintle shaft. The function of the second diaphragm is to control a bleed hole that’s held closed by a smaller spring in the main diaphragm.

This setup ensures that the EGR valve is only open when the engine is operating under a load. Negative exhaust pressure caused by the pintle being lifted pulls down the lower diaphragm and releases the negative backpressure EGR valve. You’ll know when an EGR valve is a negative backpressure valve when there’s a letter “N” at the end of the part number.

Positive Backpressure valve

The positive backpressure valve is very similar to the negative backpressure valve, as both have two diaphragms and two springs. The main difference is that the small spring in a positive backpressure valve holds the bleed hole open instead of closed. The small spring holds the bleed valve open until positive exhaust pressure causes the second diaphragm to shut. The vacuum can only operate when the bleed valve is closed.

 

If the exhaust pressure drops, the bleed valve opens and lets the vacuum out of the main diaphragm chamber. This then causes the top spring to close the EGR pintle. Positive backpressure EGR valves are labeled with a letter “P” at the end of their part number.

Electrically Operated type

Most modern vehicles come with electrically operated EGR valves mainly because they are easier to control and are more accurate than vacuum diaphragm valves. There are two types of electric EGR valves known as the pulse-width-modulated solenoid valve and the stepper motor EGR valve.

Pulse-Width-Modulated Solenoid valve

This type of electric EGR valve uses a spring-loaded valve that’s opened by an electric solenoid and closed by a return spring. The electric solenoid’s on/off cycle depends on the length of the pulse-width-modulated signal sent by the engine control module (ECM). The longer the signal, the higher the duty cycle will be and the farther the valve opens.

Stepper Motor EGR valve

The stepper motor EGR valve is better in controlling the flow of exhaust gases compared to the solenoid valve. It has a threaded rod that moves the valve in and out with the help of an electric motor. The ECM, knowing the temperature, throttle position, engine load, and vehicle speed, operates the valve much more precisely by sending signals only when the EGR flow is needed. 

Symptoms of a bad EGR valve

Despite its size, the EGR valve is critical in controlling your car’s emissions. If this component gets damaged, it won’t be able to control the flow of exhaust gases properly. As a result, your engine may produce more NOx and fail an emission test. The following are symptoms that your EGR valve may be stuck either open or closed: 

Poor engine performance

Your engine performance may begin to suffer due to a clogged or failing EGR valve. A malfunctioning EGR valve can compromise the engine’s air-fuel ratio, which could cause your fuel efficiency to drop. It can also reduce your vehicle’s power and acceleration as the problem worsens.

Illuminated Check Engine Light warning

Fortunately, most electric EGR systems use a feedback loop that ensures the proper EGR flow. If the ECM detects a circuit or position issue in the system, it will send a Diagnostic Trouble Code and illuminate the Check Engine Light or Malfunction Indicator Light. Keep in mind that an illuminated MIL could indicate a vast array of problems in your car and not necessarily a failing EGR valve. Visit your mechanic for a more accurate evaluation of what’s causing the light to turn on.

Rough idling

Rough vibrations when idling is an effect of an EGR valve that’s stuck in the open position or a vacuum leak. Rough idling usually happens when your engine is cold or at low speeds when the engine is warm. Apart from rough idling, your engine may also stall due to a constantly open valve.

Strong fuel odor

The strong fuel odor coming out of your tailpipe is caused by a malfunctioning EGR valve that won’t shut in full load conditions. This is due to the increase of hydrocarbons leaving the exhaust system. Keep in mind that hydrocarbons can cause lung diseases when inhaled.

How much is an OE replacement EGR valve?

OE replacement EGR valves on CarParts.com cost from $10 to $820. You can buy them by piece or as part of a kit. To narrow down your search, simply indicate the year, make, and model of your vehicle on the filter tab.
