Can the Car Start if Water Enters the Exhaust Pipe?

[OliveFitz]

Automobile exhaust pipes are devices installed between the engine exhaust manifold and the muffler to reduce vibration and noise, facilitate installation, and prolong the life of the exhaust silencing system. They allow the entire exhaust system to have flexible connections. Whether a car can start if water enters the exhaust pipe depends on the amount of water that has entered, which can be divided into the following two scenarios: 1. Small amount of water entry, the car can start: Typically, the wading height for cars is in the range of 50-70 centimeters, and the position of the exhaust manifold is similar in height to the intake manifold. 2. Large amount of water entry, the car cannot start: The end of the exhaust pipe has a muffler. If a large amount of water enters (such as during reverse flow when wading or when water seeps in while parked in a low-lying area with the engine off), it can accumulate in some dead corners of the muffler, eventually leading to rust and perforation.
