GDI 인젝터 구동시 연료레일 압력 맥동 변화에 따른 인젝터 작동 성능평가
Evaluation of Injector Operation Performance with Fuel Rail Pressure Pulse Changes When Driving GDI Injectors
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.
