ABSTRACT:
A unit injector mounted to a cylinder head in a diesel engine includes a pump section and a nozzle section which are eccentrically connected to each other through a connecting portion. An axis of the nozzle section is disposed in alignment with an axis of a cylinder, and an axis is of the nozzle section disposed on the opposite side of a pair of intake valves from the axis of the nozzle section. A rocker arm for transmitting the rotation of an exhaust cam shaft to the pump section is pivotally carried at its intermediate portion on a rocker shaft supported above the nozzle section. Thus, it is possible to provide a reduction in size of the cylinder head, while maintaining the spray of a fuel into a cylinder uniform, by an improved layout of the unit injector in the cylinder head.
