The working principle of the automotive oil return pipe is based on the working mechanism of the fuel supply system. When the engine is running, the fuel pump draws fuel from the fuel tank and delivers it through the fuel line to the fuel injector. In this process, the fuel pump creates a higher fuel pressure than the engine actually needs. In order to maintain the pressure balance of the system, excess fuel needs to be returned to the fuel tank through the return line
【Product advantage 】 :
1.Maintain oil pressure balance : The patency of the return pipe is crucial to the normal operation of the engine. If the return pipe is blocked, it will lead to high oil pressure, which will lead to high idle speed, insufficient combustion, lack of power and other problems, and also increase fuel consumption 34.
2.reduce fuel consumption : when the fuel pump supplies more oil than the optimal amount required by the engine, the excess fuel will be returned to the tank through the return line, thereby reducing fuel consumption
