Will the engine take in water if water splashes over the exhaust pipe?

Water splashing over the exhaust pipe can cause the engine to take in water. The following is an introduction to the exhaust pipe: 1. Introduction: The exhaust pipe is part of the engine's exhaust system, which mainly includes the exhaust manifold, exhaust pipe, and muffler. 2. Content: Generally, the three-way catalytic converter, which controls the emission of engine pollutants, is also installed in the exhaust system. The exhaust pipe usually includes the front exhaust pipe and the rear exhaust pipe. 3. Drainage: The water droplets discharged from the exhaust pipe are the result of water vapor generated after gasoline combustion condensing in the exhaust pipe and muffler. However, when the ambient temperature is high, the water vapor is discharged before it has a chance to condense.
I used to worry about this issue when driving through puddles in the rain and water splashed into the exhaust pipe. However, I later realized that water mist or a small amount of water entering the exhaust pipe doesn’t affect the engine at all. The exhaust pipe is specifically designed to expel exhaust gases and is not connected to the engine’s internal combustion chamber. If only mist or a small amount of water splashes in, the engine’s normal operation will simply expel the water without any backflow. Engine water intake mainly occurs when the air intake is submerged, such as when driving through deep puddles where water is sucked into the engine through the front grille, leading to stalling or damage. During daily driving, simply avoid deep puddles, especially after heavy rain—don’t force your way through flooded areas. I recommend regularly checking if the exhaust pipe’s drainage holes are blocked and maintaining your vehicle’s suspension and seals for added safety and peace of mind. Remember, slow down when driving through water and avoid accelerating sharply to prevent splashing.
