Summary: | The present invention relates to a high pressure oil generating apparatus of an internal combustion engine for driving valves or devices installed in the internal combustion engine with working oil. The construction consists of a cam having one and more lobes fixed to a crank shaft as one body, one and more jerk type high pressure pumps operated by the cam, a working oil source for feeding working oil to the high pressure pumps, an accumulator for accumulating high pressure working oil discharged from respective high pressure pumps and a control means, and is characterized in that the rack positions of above-mentioned respective high pressure pumps are adjusted and the working oil pressure is controlled at a predetermined pressure by the control means. Thus, the high pressure oil generating apparatus is applied practically for controlling the fuel injection quantity of the internal combustion engine and for controlling a suction/discharge valve, and particularly for controlling operation of a discharge valve. |
