Rotary mechanical diesel fuel injection pump L Orange GmbH

Fuel Pumps

Pumps which are used for the injection of fuels into diesel engines are the technically most demanding members in the family of pressure generators. The provision of fuels under high pressure to common-rail injectors and fuel injection valves calls for robust dimensioning of the pump drives, the determination of optimum clearance in the pump element and the application-oriented selection of high-strength steels with special heat treatment processes. In addition, our pumps are characterized by know-how developed over decades in terms of helices in the case of conventional pump-line-nozzle systems (PLN), component coatings, sealing elements or valve engineering. The results obtained combining hydraulic simulation, static finite elements modeling and nonlinear finite elements analysis already provides clear-cut data in the preliminary design phase as regards delivery rates and efficiency levels, component loads or lifetimes as well as the minimum surface pressures necessary for sealing.
