After the fuel pump supplies fuel to the engine, a certain pressure is formed. In addition to the normal fuel injection nozzle, the remaining fuel is sent back to the fuel tank through the oil return line. Of course, the excess gasoline vapor collected by the carbon tank is also returned to the fuel tank through the oil return pipe. The oil return pipe can return excess oil to the fuel tank, which can relieve the pressure of gasoline and reduce fuel consumption.
The role of the oil return pipe in the car's fuel tank: It is to return excess oil to the fuel tank, reducing the consumption of oil.
