Why does the exhaust pipe on the car leak water?
Exhaust pipes are the parts that conduct and process exhaust gas of a car, playing an important role for the car model and the surrounding environment.
Specifically, when the vehicle is operating, the engine part after the fuel combustion process will create power to help the vehicle operate, along with that by-products (exhaust gas) are produced, including many toxic substances such as: Carbon black, Carbon Monoxide (CO), Carbon Dioxide (CO2)...
In which H2O (water) is in the last substance, when going through the exhaust system, they will meet the exhaust processor. Here the water will be condensed, other substances will be partially absorbed and pushed out. Therefore, in the car's exhaust pipe there is water dripping when the car moves.
In addition, another reason is that in the early morning, when the exhaust pipe is still cold, the steam in the exhaust pipe will condense and become wastewater.
Another explanation is that when hydrocarbons in fuel (gasoline) are burned at about 180 degrees Celsius, some substances such as Paraffinic, Naptenic, Aromatic will exist. Then they will react with by-products produced from the fuel combustion process and create water.
Besides the above uses, the exhaust pipe also has many other uses such as pressure adjustment, noise reduction or increased aesthetics...
Some information also speculates that thanks to the phenomenon of water discharge from the exhaust pipe, the driver can also assess the condition of the car. For cars with injectors or compressed air supply parts that are not working well, the exhaust gas will contain a lot of carbon or some unusual substances. However, this hypothesis has not been verified based on the field of science or mechanics.
