What is the function of the engine exhaust pipe?

[Reyes]

Engine exhaust pipe functions are as follows: 1. It can discharge the exhaust gas generated in the engine, reducing pressure, which is an important guarantee for the continuous operation of a vehicle. 2. Noise reduction: There are two silencing systems in the entire exhaust pipe system. The first one uses the exhaust manifold that discharges the engine's exhaust gas, and the second is the main muffler at the tail of the exhaust pipe. Through these two steps of silencing, the sound of exhaust gas discharge can basically be reduced to a reasonable range. 3. Filtering exhaust gas and reducing pollution: There is a three-way catalytic converter in the middle section of the exhaust pipe. The substances inside it can chemically react with the harmful substances in the exhaust gas, thereby reducing the pollution of the exhaust gas discharge to the air. 4. It makes the vehicle look more aesthetically pleasing, and even differences in shape, such as round or square, can lead to price differences in cars.
