PURPOSE:To make the structure small and economical, by making common use of a hydraulic source by employing such an arrangement that work oil supplied to a hydraulic servo-mechanism of an injector means and a hydraulic valve driving menas of an intake and exhaust valve means and injection fuel oil are supplied from the same hydraulic source. CONSTITUTION:An apparatus of this invention comprises an injector means T for injecting fuel oil pressurized by a hydraulic servo-mechanism 33 which is controlled of the flow of work oil by a solenoid valve 31 from a nozzle valve 31 and an intake (exhaust) valve means X (Y) including a valve driving mechanism 62 for driving an intake (exhaust) valve 36 which s controlled of the flow of work oil by a solenoid valve 63. The solenoid valves 31, 63 are controlled by an electronic control unit R including a micro-computor 65. Further, a part of fuel oil supplied to the injector means T from a full oil supply means S including a fuel pump 69 driven by an internal combustion engine 68 is used as work oil for the hydraulic servo-mechanism 33 and the valve driving mechanism 62 of the intake (exhaust) valve means X (Y). |
