What is the concept of the back pressure of the car exhaust system? What is the impact on vehicle performance?
Exhaust back pressure in the vehicle system is a reference value, mainly to consider the power loss of the engine; if the power loss is small, and the back pressure value of the larger, or that the exhaust system can accept! GB requirements of the power loss should be ≤ 8% of the rated power of the engine
Exhaust back pressure on the engine in the work indicators have a certain impact
Yes, it can be understood as the exhaust resistance, which corresponds to the intake resistance
