Why does a car drip water in summer?

[BrynleeFitz]

It is a very normal phenomenon for a car's exhaust pipe to drip water in summer. The reason why a car's exhaust pipe drips water is that water and carbon dioxide are produced after the gasoline is completely burned, which indicates that the engine is working normally and the atomization effect is good. If the exhaust pipe emits mist, it indicates that the engine is in excellent condition. The reasons for the drainage of the air conditioning system are as follows: 1. Reason one: Due to the high temperature inside the car, the cooling system needs to be activated to reduce the temperature inside the car. At this time, the moisture in the hot air inside the car will condense on the surface of the evaporator's heat-absorbing fins, which have a very low temperature. The water droplets are collected by the plastic shell of the evaporator and discharged out of the car through the pipes. 2. Reason two: The low-pressure pipes of the car air conditioner are not wrapped with insulating foam, and the surface of the pipes is prone to condensing moisture in the air. The water droplets will also drip down from the lowest point of the pipes.
