Automobile exhaust pipe is the exhaust pipe. However, many people recently discovered that the exhaust pipes of their own cars sometimes appear to be dripping. Is this an automobile problem? But where did this water come from? Don't worry, drip is a normal phenomenon. Because gasoline is mainly composed of hydrocarbons, it will produce water vapor and carbon dioxide after it is completely combusted, and the water vapor will be condensed to form liquid water. When it reaches a certain amount, it will be discharged through the exhaust pipe. This is what we have seen as the phenomenon of drainage of automobile pipes.
In fact, this phenomenon is related to the design of the car. The exhaust pipe usually has a small hole, which is used for drainage, and some of the tail of the tail pipe design is lower, so that the water will be discharged during driving, which is why you can see the car The exhaust pipe of the front car is pulled out of the water, and the middle of the exhaust pipe is relatively low. The manufacturer will make a hole in the lowest part of the middle of the exhaust pipe to allow the water to drain.
Of course, there is a case where the discharge of water from the exhaust pipe is not normal. That is, when the cooling water in the engine is exposed to the combustion chamber, causing the exhaust pipe to leak, it is sufficient to see if the water in the engine compartment cooling tank leaks. . In addition, if the rear exhaust pipe is found to emit black smoke, it indicates that the gasoline of the automobile engine is excessively burnt, the cylinder air pressure is too low, or the individual cylinders do not work, and inspection and repair are required.
In fact, the car's exhaust pipe drip shows that the car's engine is in good condition, the car has been fully burned, the oil supply system is in good condition, and it also represents the fact that the cylinder is not worn, and you don't have to worry about it.
Last tip: If the exhaust pipe has long-term water retention, it should also be noted because it may be corroded. So you guys have to pay attention to it.
Editor's Note: The dripping of the exhaust pipe is normal, and it is more common in new cars, whether it is a low-end car or a luxury car. And this situation does not mean that your car has a problem. On the contrary, this is a good engine performance.
