What Causes a Large Amount of Water to Spray from the Car Exhaust Pipe?

[KennedyDella]

Water spraying from the car exhaust pipe occurs because the engine temperature is high, causing water to exist in the form of vapor. When this vapor encounters the cold outside air, it condenses into small water droplets on the exhaust pipe walls and flows out along the pipe. There are three key methods for maintaining the exhaust pipe: 1. Waterproofing: When driving in the rain or washing the car, ensure the muffler does not take in water. If water enters the muffler, immediately start the engine to heat the car and allow the accumulated water to drain out. 2. Rust Prevention: Apply anti-rust oil by first removing the muffler, blocking the drainage hole, applying the oil, shaking the muffler to distribute the oil evenly inside, and then reinstalling it. 3. Cleaning: If dirt accumulates inside the exhaust pipe, it can impair its normal function. Since the exhaust pipe is often exposed to the outside yet connected to the car's interior, internal dirt buildup can hinder its proper operation.
