CONTROL DEVICE FOR FUEL JETTING OF INTERNAL COMBUSTION ENGINE

摘要

PURPOSE: A control device for fuel jetting of an internal combustion engine is provided to certainly improve the engine starting property by being able to raise the inside of an accumulating room by a fuel pressure to be able to jet the fuel in a short time at starting the engine. CONSTITUTION: The control device for fuel jetting of the internal combustion engine comprises:an accumulating room(2) to supply a pressurized fuel into a fuel jetting valve(1); a high pressure pump(7) to vent the fuel to the accumulating room with an engine body as a power source; a low pressure pump(4) to vent the fuel to the high pressure pump with except the engine body as the power source; an opening and closing valve(16) installed in an inhaling passage to connect a vent side of the low pressure pump and an inhaling side of the high pressure pump; the opening and closing valve(16) to perform an overflow valve to be opened to prevent the vent of the amount of vent fuel to the accumulating room in a vent process of the high pressure pump.
