Let's give another brief introduction. What is EGR rate? EGR rate refers to the ratio of the amount of exhaust gas entering the engine for secondary combustion to the amount of fresh air, which is called EGR rate.
After passing through EGR, the exhaust enters the engine for combustion again through the engine intake duct, and the opening of the intake throttle valve will also be adjusted. Ensure that an appropriate amount of fresh air is mixed with cooled exhaust to form the optimal ratio for combustion in the engine.
Cardholders do not need to worry about exhaust flow taking the lead in fresh air, causing problems such as insufficient power. Because the amount of exhaust gas entering the engine during diversion has already been calculated, the ECU will tell the throttle valve what opening it should reach.
How does EGR cool the exhaust gas? Relying on the exhaust cooler connected to the EGR, the exhaust temperature of the engine can reach 600-700 degrees. The antifreeze circulating in the exhaust cooler continuously cools the exhaust, ensuring that the engine can suck in air at the appropriate temperature.
You don't have to worry about the service life of EGR at all. Through on-site inquiries at the internal combustion engine exhibition, it was found that domestic manufacturers can now achieve EGR performance similar to engines, with a B10 service life of 1.5 million kilometers.
