The advancement of diesel fuel injection systems is forced by the increasingly stringent exhaust emissions limits. Modern injection systems must generate fuel pressure in excess of 200 MPa, which very often leads to premature wear of the mating components. Generating high pressures results in much force load acting on the pumps. In the case of frequently applied cam-driven pumps, high loads result in significant forces caused by friction. The friction force loads the piston perpendicularly to its axis, which rules out the application of super hard but fragile materials such as ceramics. One of the possible solutions of this problem is the application of unconventional drive systems, the example of which is the hypocycloidal drive. The paper presents the results of simulations comparing selected parameters of the piston motion of the cam-driven pumps and the pumps fitted with hypocycloidal drive. The use of the CAD software also enabled identification of the force acting on the piston (force perpendicular to the piston axis) in the cam-driven pump and its lack in the pump fitted with hypocycloidal drive.
