Is It Normal for the Exhaust Pipe to Have Water in Winter?
1 Answers
It is a very normal phenomenon for the exhaust pipe to drip water in winter. After gasoline is completely burned, it produces water and carbon dioxide. At high temperatures, the water is in the form of steam, but when it comes into contact with the cooler exhaust pipe, the steam condenses into liquid water. Therefore, it is natural for some cars' exhaust pipes to drip water in winter. The following points prove that water dripping from the car's exhaust pipe is normal: 1. Correct air-fuel mixture ratio: When the vehicle's air-fuel mixture ratio is correct, water dripping from the exhaust pipe is normal. Whether it's an electronic fuel injection or carburetor engine, a correct air-fuel mixture ratio indicates that the vehicle's compression ratio is normal, and fuel consumption is within the normal range. 2. Normal engine cylinder pressure: When the vehicle's exhaust pipe drips water normally, it indicates that the engine cylinder pressure is normal, and it also shows that there is no wear in the engine cylinder block. All parts inside the engine can work properly, and this method can be used to determine whether the fuel is burning normally. 3. Normal exhaust temperature: Normal water drainage from the vehicle's exhaust pipe also indicates that the exhaust temperature is normal, meaning the engine's power output is stable.
