ABSTRACT:
A unit injector is disposed on a cylinder head in an oblique state and rocker arms for actuating intake and exhaust valves, respectively, are disposed on both sides of the unit injector. Another rocker arm for actuating the unit injector is disposed between these two rocker arms. Support beds for supporting a rocker arm shaft that supports both rocker arms for actuating the intake and exhaust valves and another rocker arm shaft that supports the rocker arm for actuating the unit injector are formed as a unitary structure. One cam shaft for operating the rocker arms for actuating the intake and exhaust valves and the rocker arm for actuating the unit injector is disposed at a low position on the side of the unit injector as close as possible to the axis of a piston. A governor for adjusting the fuel injection quantity of the unit injector is fitted to one end of the cam shaft, in which the arrangement is such that the governor is operatively associated with a control rod disposed parallel to the crank shaft, which rod is operable in association with each unit injector to adjust the fuel injection quantity.
