2020年9月19日 · EGR stands for exhaust gas recirculation, a vehicle emissions control concept used in both gasoline and diesel engines. The EGR valve — which works differently depending on how old the car...

Integral to the vehicle’s engine management system, the aptly named exhaust gas recirculation valve, or EGR valve for short, recirculates finely metered quantities of exhaust gas to the engine intake system for increased engine efficiency, reduced fuel …

What does an EGR valve do? The EGR valve routes a portion of your exhaust gases into the engine’s intake to reduce combustion temperatures. This helps prevent the formation of Nitrogen Oxides, or NOx, which are pollutants.

The EGR valve is the main component of the EGR system and it's normally closed. It connects the exhaust manifold to the intake manifold and is controlled by either a vacuum or a built-in electric step motor.

What Is an EGR Valve? The EGR valve is a component in the engine’s emission control system. Its primary job is to recirculate a portion of the exhaust gases back into the engine’s intake system.

2024年7月7日 · Integrated into the vehicle's engine management system, the aptly named exhaust gas recirculation valve, or EGR valve for short, recirculates precisely metered amounts of exhaust gas into the engine intake system for higher engine efficiency, lower fuel consumption and lower NOx emissions.

2022年10月11日 · All vehicles are fitted with exhaust systems, and EGR valves are one of these elements. EGR valves allow harmful gas to re-enter the intake system, changing the chemical composition of the returning air.
