FUEL SYSTEM - STRUCTURE AND FUNCTION
The block assembly in place can be angularly repositioned, relative to the pump housing, by turning the flange sleeve. Turning the block affects the injection timing. Thus, the relationship between the plunger and the inlet port is determined by the angular and vertical positions of the block assembly in the housing.
The pressure-feed lubrication mentioned previously refers to the tappets. Pressurized lubricating oil is led into the pump housing from the engine lubricating system. An oil orifice opens out into the bore in which the tappet reciprocates in sliding contact. The oil is forced through the orifice into this sliding clearance around the tappet. The camshaft and the moving parts in the governor are lubricated with this oil. A return line is provided to return the oil back to the engine lubricating system.
