Oil Pumps for Internal Combustion Engines and Transmissions Conventional, Variable and Electrical

Oil pumps for internal combustion engines – conventional, variable and electrical Virtually all the engine makers use Pierburg Pump Technology oil pumps, customers including the global car and commercial vehicle industries. On an I.C. engine, the oil pump is one of the those components selected at the drawing board stage since the quality of its design and execution is a major ingredient in sustaining the upgradeability of the basic engineering throughout many years of series production. Highly efficient R&D centers in Italy, France, and Germany, operate large numbers of engine test rigs and...

Innovative oil pumps With in some cases additional oil/hydraulic functions to perform such as hydraulic valve lifting/timing, piston cooling, and the use of aluminum engine blocks, today’s engines require disproportionately large oil flows, especially at low engine RPM. On conventional, unregulated pumps this leads to substantial losses (Fig. 4) at higher engine speeds since the output of these pumps is locked to engine RPM. Pierburg Pump Technology has mapped out a variety of approaches with a view to ensuring dependable lubrication and reliable regulation of the oil supply system under all...

ing on the strategy, good results can be achieved with an electronic control over two different pressure stages. Going beyond this, continuous pressure control permits a further improvement in the results even outside the test cycle. By referring to the NEDC, the oil pump’s power consumption can be reduced by up to 70 % by using this technology. The effect on fuel consumption is a reduction up to 3 %. Variable oil pumps can be integrated in modules including vacuum pumps, water pumps, balancer shafts. Pierburg Pump Technology’s design department has highly advanced design and simulation tools...

Electric oil pumps For hybrid drives and engines with automatic start-stop, the use of electric gear oil pumps is indispensable if hydraulic pressure has to be maintained in the subsystems after the internal combustion engine has been switched off. Electrical oil pump can be used also in combination with mechanical oil pump of the engine as a booster pump, or in any case is needed oil pressure to actuate devices independently from the thermal engines. For the development of new oil pumps, Pierburg Pump Technology exploits synergies with the electrical water pumps and thus cuts costs and development...
