초록 ▼

A fuel injection system of an engine comprises a fuel tank, a fuel pressure pump for pressurizing a fuel supplied from the fuel tank, an injector connected to the fuel pressure pump by means of a fuel pipe. The injector includes a nozzle connected to the fuel pipe by means of a fuel passage, a pressure chamber into which the pressurized fuel is introduced from the fuel passage, and a nozzle valve for opening and closing the nozzle depending on the fuel pressure in the pressure chamber. The system further comprised a fuel return passage connecting the pressure chamber and the fuel tank, and first and second solenoid valves for determining the start and termination of fuel injection through the nozzle.

대표청구항 ▼

[ What is claimed is:] [1.] A fuel injection system of an engine, comprising:a fuel tank for storing a fuel:a fuel pressurizing device for pressurizing the fuel supplied from the fuel tank;an injector for injecting the fuel pressurized by the fuel pressure device into a cylinder of the engine;a fuel supply passage for connecting the fuel pressurizing device and the injector and for supplying the pressurized fuel from the fuel pressurizing device to the injector;a fuel return passage for connecting the injector and the fuel tank and for returning the pressurized fuel from the injector to the fuel tank;at least two solenoid valves arranged in the fuel return passage, said solenoid valves being opened and closed to control fuel injection from the injector, andan accumulator disposed in the fuel supply passage, whereinsaid injector includesa nozzle connected to the fuel supply passage by means of a connecting passage such that the pressurized fuel is injectable through the nozzle,a pressure chamber into which the pressurized fuel is introduced from the connecting passage, anda nozzle valve for opening and closing the nozzle depending on the fuel pressure in the pressure chamber,said fuel return passage connects the pressure chamber and the fuel tank,said solenoid valves are arranged in series in the fuel return passage, andsaid nozzle valve opens the nozzle to inject the fuel through the nozzle when all the solenoid valves are opened to lower the fuel pressure in the pressure chamber.
