What is an EGR valve, and what does it do?

First, let’s look at what EGR stands for—Exhaust Gas Recirculation. We know that this component is part of your exhaust system, but what does it do? Well, if all the gases produced by your engine were fed back into the atmosphere in one go, the resulting harmful emissions would be way over the acceptable thresholds for healthy operation.

The EGR valve feeds part of your engine’s exhaust fumes back into the combustion system, reducing the amount of clean air it needs to do the same job. In turn, this reduces the operating temperature as most of the gas it feeds back is carbon dioxide, and that doesn’t burn. The resulting lower temperature prevents those harmful nitrogen oxides from forming, reducing the amount that is released during each pass.

What are the symptoms of a failing EGR valve?

As part of the exhaust system, the first thing you’re likely to spot if your EGR valve isn’t working correctly is the black smoke coming out of your car’s exhaust. You might also notice a drop in engine power, poorer fuel economy, and an unhappy sounding and performing engine that stalls regularly and feels far rougher while idling. There’s also a strong chance your engine management light will illuminate on your dashboard.
