Why is water dripping from the Dongfeng Yulon exhaust pipe?
1 Answers
This is a very normal phenomenon. After safe combustion, gasoline generates carbon dioxide and water vapor. The water vapor condenses to form liquid water, which is discharged through the exhaust pipe when a certain amount accumulates. Relevant explanations are as follows: 1. Water dripping from the exhaust pipe is commonly seen in new cars, regardless of whether it's an economy car or a luxury vehicle. The accumulation of condensed water droplets indicates efficient combustion of gasoline in the engine, as complete combustion of gasoline produces water vapor and carbon dioxide. When the ambient temperature is low, the white smoke emitted from the exhaust pipe is water vapor. When the water vapor flows through the metal pipe, it condenses into water droplets, which will flow out when a certain amount accumulates. 2. Water dripping from the exhaust pipe reflects the vehicle's performance, but more is not necessarily better. Excessive water in the exhaust pipe can damage the oxygen sensor in the catalytic converter, leading to inaccurate fuel supply to the engine and affecting the vehicle's performance. On the other hand, prolonged retention of water droplets in the exhaust pipe can also accelerate pipe corrosion.
