DRIVE SYSTEM OF A HIGH-PRESSURE FUEL PUMP, HIGH-PRESSURE FUEL PUMP ASSEMBLY AND INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a drive system (10) of a high-pressure fuel pump (12) of an internal combustion engine (14), said system comprising a drive train which is coupled on the input side to a crankshaft (18) and on the output side to a valve-controlling camshaft, and comprising at least one drive-system cam (26) which drives the high-pressure fuel pump (12) directly and is situated in the drive train at a distance from the valve-controlling camshaft. The drive system has no chain and no toothed belt for driving the drive-system cam. The invention also relates to a high-pressure fuel pump assembly and to an internal combustion engine.
