Step on the gas pedal hard and spray water on the exhaust pipe. What happened?

The specific reasons why the exhaust pipe will spray water when you step on the accelerator hard are: 1. It is a normal physical phenomenon to spray water on the exhaust pipe of an automobile when stepping on the accelerator, and it is also a full performance of gasoline combustion;

2. After gasoline is burned, it mainly produces carbon dioxide, water and a small amount of carbon monoxide. 1kg gasoline mixed with air produces 1.42kg water, which is mainly discharged into the atmosphere in the form of steam.

3. Because the main muffler is located at the rear of the car, the temperature is relatively low, and it is a multi-chamber structure, which is easy to form water. When the engine is running at high speed, the accumulated water inside will be discharged under the action of airflow, which is a common phenomenon of water spraying. For vehicles that often drive at low speed in congested sections, especially in winter, the phenomenon of water accumulation in silencers will be slightly more serious.
