Abstract
PURPOSE: To properly operate a diesel engine despite the change in its rotational frequency, by using the first and the second solenoid valves to determine the time of injection and the quantity of fuel based on a free piston which acts in response to a plunger pump.
CONSTITUTION: At the time of suction by a pump 5, fuel supplied under pressure flows into the measuring chamber A of a free piston unit 7 through a solenoid valve 12 and a check valve 8 and fuel on the opposite side is sucked into te pump 5. When the displacement of a free piston 7b has reached an extent corresponding to a quantity of fuel dependent on the working state of an engine, the solenoid valve 12 is closed. At the time of compression of the pump 5, a solenoid valve 5 is opened and fuel flows out to a return pipe 4 through a check valve 14. When injection time dependent on the working state of the engine has come in the compression of the pump 5, the solenoid valve 15 is closed and the free piston 7b is pushed by the pressure of a plunger 5 to inject a measured quantity of fuel into a cylinder through an injector 6.
