摘　　要：本文介绍了电子机油泵的结构原理。通过摩擦功和燃油消耗量试验对比,结果表明采用电子机油泵以后,整机摩擦功和油耗都显著降低,对提高发动机的热效率有明显的作用。采用电子机油泵后,在2000rpm&2bar收益为0.7g/kWh,万有特性工况下有2-15g/kWh的油耗收益。本文也指出目前电子机油泵的存在的问题,并对今后的研发方向提出了一些看法。This paper presents the principle structure of electronic oil pumps(EOP).The test results of friction work and fuel consumption are significantly reduced after the usage of EOP.It also has an obvious effect on improving engine braking thermal efficiency.After the usage of EOP,0.7g/kWh was obtained at 2000rpm&2bar,2-15g/kWh were obtained on the whole engine maps.This paper also points out the existing problems of EOP,and brings some ideas on the future research and development.
