Abstract
A fuel injection pump element 15 is mounted in an engine crankcase (1) adjacent its associated cylinder 9, and in substantially parallel orientation thereto so that the high pressure outlet 20 of the injection pump element 15 is close to the injection valve 13 thus permitting a very short injection line 21. Mounting the fuel injection pump element 15 within the crankcase provides a very rigid mechanical support therefor. Use of a very short fuel injection line provides superior hydraulic rigidity as is required for achieving high injection pressures. A special bushing 31 with fuel passage may be used to mount the pump plunger bushing 19. The special bushing 31 may be made of high quality material of low porosity to add strength and avoid fuel leakage that may otherwise occur because of the porosity of the case iron crankcase.
