What is a carbon canister? What is an oil-gas separator? Where is it usually located?

Gasoline may have a carbon canister, because gasoline will volatilize, which will pollute the environment if it is directly discharged into the atmosphere. Therefore, in order to protect the environment, the gas volatilized from gasoline will be stored in the carbon canister, and then the intake pipe will be connected with the carbon canister, so that the gas volatilized from gasoline will be absorbed and utilized by the engine after the engine is started, which is both environmentally friendly and economical! If it is a van, the carbon canister is generally next to the throttle, and if it is a car, the carbon canister is generally in front of the fuel tank. . Oil-water separators are usually used in diesel engines. It will precipitate the water in the fuel to ensure the quality of the oil. Many cars are installed by themselves, so there is no designated location. It is installed on the intake pipe, so it is generally next to the fuel tank.
