KOHLER injection system is being steadily implemented, seeking the best performance of its engines.
For this reason the pump injector body has been modied three times in the course of its evolution.
Three different pump injectors are shown in the top gure.
Old type injector pump:
it is characterised by its high pressure hole
Intermediate injector pump: is characterised by not having the high pressure hole (the hole can be there but it is only used
to control the injector and injection advance) and by the locating peg between inlet and outlet
holes.
Current pump injector: it is characterised by its offset inlet and outlet holes. These are also oversized, due to the
absence of the high pressure hole.
