Most of the dripping water from the exhaust pipe of the car occurs in new cars. Many car owners will be surprised when they find it. Do they think there is something wrong? Why is it okay to drip water? The old driver will say that this is a normal situation. Today, let's talk about dripping water from the exhaust pipe!
Let's first show that the dripping water from the exhaust pipe during driving is also the embodiment of the complete combustion of gasoline in the engine!
In winter, we can see that the exhaust funnel emits white smoke, that is, water vapor. When the exhaust funnel is too cold, the water vapor will also condense into small water droplets, rarely into many, flowing out of the exhaust funnel!
You will also think that dripping is also a good thing. Why do some cars drip and some don't drip? No, cars don't burn well, too? In fact, there are three conditions for dripping water from the exhaust pipe:
1. The fuel air mixture ratio of the vehicle shall be correct
Whether the automobile engine EFI or carburetor, it also shows that the automobile oil supply system is normal, the compression ratio is normal, and the automobile fuel consumption is within the normal range!
2. The cylinder pressure of automobile engine is normal
The normal cylinder pressure of the automobile indicates that there will be wear in the cylinder block of the automobile engine, as well as some parts such as cylinder liner and sealing ring. If there is wear in the automobile engine, it will also reduce the cylinder pressure. Finally, it is incomplete combustion, and there will be no water!
3. The exhaust temperature of the vehicle shall be normal
The heat generated by automobile engine workmanship is in the cylinder. As long as a small amount of heat will overflow into the exhaust funnel, it also shows that the engine power output is stable. If the exhaust funnel temperature is too high, water vapor can not form water droplets!
Too much water in the automobile exhaust funnel will also have an impact on the oxygen sensor in the three-way catalyst. The oxygen sensor mainly monitors the oxygen content in the exhaust gas, and then forms an electrical signal. The ECU judges the size of the air-fuel ratio according to the electrical signal fed back by the oxygen sensor, and then adjusts the fuel injection quantity, resulting in the engine maintaining the best air-fuel ratio!
There are small openings under each exhaust pipe, one is for drainage, and the other is to avoid water flowing out normally due to exhaust problems when wading!
If water is stored in the exhaust pipe for a long time, it is also hoped to detect whether the small hole of the exhaust pipe is blocked. If it is blocked and cannot be dredged, the exhaust pipe will be corroded very quickly If a there is water in the exhaust funnel for a long time, it is not far from corrosion!
