Why is the Honda Vezel's exhaust pipe spraying water so much?
1 Answers
There are two situations when the Honda Vezel's exhaust pipe sprays a lot of water: one indicates that the gasoline is burning fully, achieving a very high utilization rate. The other suggests that the fuel being used is of poor quality with excessive water content. The details are as follows: 1. Exhaust system: The exhaust pipe is part of the engine's exhaust system, which mainly includes the exhaust manifold, exhaust pipe, and muffler. Generally, the three-way catalytic converter, which controls engine pollutant emissions, is also installed in the exhaust system. The exhaust pipe usually consists of the front exhaust pipe and the rear exhaust pipe. 2. Principle: A back-pressure exhaust pipe will sound better than the original factory one. Most original factory vehicles use this type of pipe, which mainly relies on the baffle muffler inside the pipe or the volume change of the pipe to generate a pressure that returns to the cylinder. When the engine ignites, the piston begins the power stroke, and the exhaust valve opens before the piston reaches the bottom dead center. At this time, the back pressure in the pipe will block the exhaust gas from rushing out, allowing the air-fuel mixture to achieve complete combustion. However, if the back pressure is too strong, it will prevent the exhaust gas from being completely discharged from the cylinder, causing the exhaust gas to burn together with the air-fuel mixture, reducing combustion efficiency. Of course, the most direct impact is on horsepower output.
