There is water flowing out of the exhaust pipe of the automobile engine. Can you explain that the engine is in good condition?

There is clear water discharged from the end of the engine exhaust pipe, which shows that the engine burns fully and basically reaches the ideal state, but nothing is absolute. In winter, because the outside temperature is too low, the exhaust pipe and three-way catalytic temperature are very high, and the temperature difference between high and low will also produce water vapor and water. To put it bluntly, water droplets will still be produced when the engine is not working well in winter, so you will see white smoke from the exhaust pipe of the car in winter, which is actually water vapor!

Where does the water in the exhaust pipe come from?

When gasoline is completely burned, it will produce tail gas, which contains carbon dioxide, carbon monoxide, solid carbide, water vapor and so on. When the ambient temperature is low and the exhaust pipe temperature is low, the exhaust gas flows through the tortuous exhaust pipe and meets the three-way catalyst and exhaust pipe with relatively low temperature, and the water vapor condenses into water!

After gasoline is burned, water will also be separated. The water in gasoline will evaporate into steam at high temperature and then condense into water!

If the water in the exhaust pipe cannot be discharged and remains in the exhaust pipe, will it affect the car?

The impact is definitely there! If water cannot be discharged from the exhaust pipe, it will directly corrode the exhaust muffler, resulting in internal corrosion of the muffler, which will not play a silencing role!

Be careful in winter. If there is too much water in the muffler, the water will freeze in the muffler after parking in winter, causing the exhaust pipe to be blocked! It may be difficult or impossible to start tomorrow morning. Due to insufficient exhaust, the car will indirectly lack power and accelerate weakly.
