FIELD: mechanical engineering.
SUBSTANCE: disclosed are methods and systems for diesel engine fuel injection gear pump. In one example front end of engine comprises an intermediate gear engaged with the first end of a crankshaft and a driving gear of a fuel pump engaged with the intermediate gear. The front end of the pump can additionally comprise a fuel pump, with input shaft of the fuel pump being directly connected to the driving gear of the fuel pump.
EFFECT: the technical result consists in reducing lateral load on bearings of the fuel pump as well as reducing friction loss and extending service life of the fuel pump.
