Analysis on Driwing Forces of Oil Pumps for Internal Combustion Engines 860230
Measures to reduce friction losses for internal combustion engines have been promoted as a means to meet the recent socioeconomical demand for energy saving.
This paper describes a unique study on oil pump driving forces as a part of such efforts.
In this study, oil pump driving forces are divided into (!) pumping work, (2) gear intermeshing loss, (3) resistance by the viscosity of lubricating oil, (4) mechanical loss and (5) bearing friction loss.
Individual driving forces have been analyzed by respective theories, which are synthesized into a theoretical equation.
The comparison between the theoretically calculated values and measured values obtained by the tests has revealed that they are in good agreement, as being described in the text of the paper.
