Abstract

PURPOSE: To facilitate starting by installing the spring for varying the valve opening pressure onto the nozzle of a fuel injection apparatus and lowering the spring pressure on engine starting.
CONSTITUTION: An injector 12 consists of three solenoid valves 32, 34, and 36 which are controlled by a controller 14, the spool valve 30 which shifts horizontally by means of each described above valve, the plunger 28 of which vertical movement is controlled by the valve 30, and the nozzle 26 of which turning is controlled by the plunger 28. The pressure source 10 consists of a pump 18 and an accumulator 24 etc., and fuel is supplied into the nozzle 26. The valve opening pressure setting spring 52 having the movalbe member 54 which slides in a cylinder 56 fixed in the top part is installed on the nozzle 26, and the fuel pressure from the pump 18 always operates onto the top part of the member 54. The spring 52 extends on starting when the fuel pressure of the pump 18 is low, and the valve opening pressure from the nozzle 26 reduces lower than the normal pressure.
