exhaust gas pipe

The exhaust gas pipe is a part of the engine exhaust system. The exhaust system mainly includes exhaust manifolds, exhaust pipes and mufflers. Generally, the three-school catalysts that control the emission of engine pollutants are also installed in the exhaust system. The trachea generally includes a front exhaust pipe and a rear exhaust pipe.

Auto part used in the Gas exhaust system

Back pressure exhaust gas pipe
(It is more environmentally friendly like the original factory) The principle is the same as that of the original factory, but the sound will be better than the original factory. Returning the pressure to the cylinder, when the engine fires, the piston begins a radial power stroke, and the exhaust valve opens before the piston reaches bottom dead center.

At this time, the back pressure in the pipe will block the exhaust gas from rushing out, allowing the mixture to achieve complete combustion. However, if the back pressure is too strong, the exhaust gas will not be completely discharged from the cylinder, causing the exhaust gas and the mixture to burn together to reduce the combustion efficiency. Of course, the most direct one is the output of horsepower. Its advantages: low noise, good low-speed torque. Disadvantages: The exhaust gas cannot be quickly discharged at high speed, which affects the power output of the engine and the volume is low.

Half back pressure exhaust gas pipe
Of course, the back pressure of this exhaust gas pipe is lower, and the smoothness of the exhaust is better than that of the back pressure pipe. Simply put, it has a moderate back pressure between the back pressure pipe and the straight pipe to obtain the starting torque exhaust. The gas compliance is better than that of the back pressure pipe, and of course the torque at medium and high speeds is also larger than that of the back pressure pipe. Advantages: The torque performance is good at start, middle and tail speed. Disadvantages: The noise is too loud and the volume is louder.
