What Are the Reasons for Water Dripping from the Car Chassis in Summer?
1 Answers
There are three main reasons for water dripping from the car chassis in summer. Below is a detailed introduction to these three reasons: 1. Drainage holes to prevent water accumulation on the body: In addition to normal drainage from the air conditioning system, muffler, and exhaust pipe, which are part of the car's internal operating systems, the car chassis is also equipped with specially designed drainage holes to remove accumulated water from the body during rain or snow. These drainage holes include the engine compartment drainage hole, sunroof drainage hole, door drainage hole, and trunk drainage hole. 2. Air conditioning system drainage: It is normal for the air conditioning system to drain water in summer. During summer, moisture from the hot air inside the car condenses on the very cold heat-absorbing fins of the evaporator and is collected as droplets by the plastic casing of the evaporator, then drained out of the car through pipes. 3. Water dripping from the muffler and exhaust pipe at the rear of the car: Water dripping from the muffler and exhaust pipe at the rear of the car is also normal. Gasoline is injected into the cylinders and mixed with air. After complete combustion in the combustion chamber, it mainly produces carbon dioxide and water. At high temperatures, the water is discharged into the atmosphere as gaseous water vapor. Since the muffler is located at the rear of the car where the temperature is relatively low, the water vapor condenses into liquid water when it cools down.
