초록
In this paper, we break away from the method of removing and inspecting the GDI injector, measure the pressure change of the fuel rail pressure sensor when driving the GDI injector of a vehicle equipped with the GDI fuel system, and compare the results. analyzed.There was a pressure change in the fuel rail pressure sensor from the general drive GDI injector. There was no pressure change in the fuel rail pressure sensor when driving the GDI injector without injecting fuel. You can check the fuel injection status in the pressure change data of the fuel rail pressure sensor without removal the GDI injector.
