The camshaft is the central drive component. It drives the pump elements that generate the high pressure and delivers the fuel. The robust pump elements consist of pistons, cylinders, corresponding suction and pressure valves, including a seal element and a roller plunger that transfers the drive forces from the camshaft to the piston. The high-pressure accumulator integrated in the high-pressure pump allows for a flexible engine design, minimizes overpressure and guarantees a consistently high pressure in the injection system.
