How Does My EGR System Work? 

The exhaust gas recirculation (EGR) system is an emissions control device that is used in internal combustion engines to reduce the number of harmful nitrogen oxides (NOx) that are emitted into the atmosphere. The EGR system works by recirculating a portion of the exhaust gas back into the engine's combustion chamber, where it helps to reduce the temperature of the combustion process. This reduction in temperature can help to reduce the formation of NOx, which is formed at high temperatures during the combustion process.

What Does An EGR System Consist Of? 

The EGR system typically consists of an EGR valve, an EGR cooler, and an EGR tube. The EGR valve is used to control the flow of exhaust gas into the engine, while the EGR cooler helps to reduce the temperature of the exhaust gas before it is recirculated. The EGR tube carries the exhaust gas from the exhaust manifold to the intake manifold, where it is mixed with the incoming air and fuel.

How Is An EGR System Controlled? 

The EGR system is typically controlled by the engine's electronic control module (ECM), which uses sensors to monitor the engine's operating conditions and adjust the EGR valve as needed to maintain the correct amount of exhaust gas recirculation. The ECM may also use other sensors, such as oxygen sensors and intake air flow sensors, to monitor the engine's performance and adjust the EGR system as needed.
