Why Does Water Drip from the Front of the Exhaust Pipe?

[Jimenez]

Water dripping from the front of the exhaust pipe occurs because the complete combustion of gasoline in the engine produces water vapor and carbon dioxide. When the water vapor flows through the metal pipe, it condenses into water droplets, which then flow out through the exhaust pipe. Conditions for water dripping from the exhaust pipe: The air-fuel mixture must be correct, the compression ratio must be normal, and fuel consumption must be within the normal range. The engine cylinder pressure must also be normal. If there is internal wear in the engine, it can lead to reduced cylinder pressure and incomplete combustion. The exhaust temperature must be normal, indicating stable engine power output. If the exhaust pipe temperature is too high, water vapor cannot form droplets. Exhaust pipe drainage design: There is a small hole at the bottom of each exhaust pipe, serving two purposes: first, to drain water, and second, to prevent water from failing to flow out properly due to the exhaust angle when driving through water.
