How does the EGR system in a car work?

Many modern vehicles are equipped with an EGR system to help lower the vehicle’s emissions. The EGR system works by recirculating exhaust gases back into the engine in order to lower cylinder temperatures and NOx emissions. The EGR system is made up of several components that work together to accomplish this task.

How to test an EGR valve, a simple procedure?

Connect a hand vacuum pump to the EGR valve in place of the vacuum hose and apply 15 in-Hg of vacuum to the valve (if you don’t have access to a vacuum pump you may borrow-rent one from a local auto parts store). As you apply vacuum to the valve, check for diaphragm movement.

What happens when the EGR valve fails to close?

When this flow pattern fails, you begin to notice a decline in engine performance. For instance, this will happen if the EGR valve fails to close completely as the engine idles, or fails to open when engine speed increases. Unfortunately, problems in the EGR system and valve will happen sooner or later.

How is exhaust gas circulated in an EGR system?

Most EGR systems have a by-pass valve integrated with the EGR cooler. When the engine is cold, the exhaust gas is circulated directly into the engine.

Where is the vacuum diaphragm on an EGR valve?

The hose connects the top of the valve to the throttle body or carburetor. The valve’s metal disk houses a vacuum diaphragm, spring, and plunger. Later models come equipped with electronic-vacuum EGR valves inside a small block or cylinder.

Where are the EGR Jets in the intake manifold?

A more radical design, implemented in a few models, was the replacement of the valve with EGR jets at the bottom of the intake manifold. Some newer high-efficiency engines, for example those with variable valve timing (VVT), don’t even use an EGR system. If playback doesn’t begin shortly, try restarting your device.

What should I do if my EGR valve is not working?

Remove the EGR valve and check if it’s opening when you are using the vacuum pump. If the EGR valve is working properly, check the solenoid that is controlling the EGR valve, and check if you have power and ground to it.

What are the different types of EGR valves?

This helps to ensure the car maintains fuel efficiency and emits fewer emissions. There are two types of EGR valves; a vacuum-operated and an electronically controlled EGR valve. A vacuum-operated EGR valve is usually only found in older vehicles. It is a straightforward system which utilises a vacuum to switch the EGR valve from closed to open.

How to test an EGR valve with a hand mirror?

As you do this, watch the valve diaphragm movement. Use a small hand mirror for this, if necessary. If the stem or diaphragm doesn’t move, disconnect the thin vacuum hose from the top of the valve. Place your finger on the opening of the vacuum hose you just disconnected. Increase engine rpm again as you did in the previous step.

What happens when the EGR temperature sensor fails?
