Abstract: Simulation and experiment study on the main oil gallery pressure feedback control lubrica tion system of gasoline engine were conducted. In the steady state simulation, a series of parameters e, g. oil o(extreme condition) were compared and analyzed, And the transient state simulation was performed in conditions while the engine under normal state was accelerating from 3 500 r/min to 4 500 r/min, Finally, the simulation results were verified by oil pump test and engine bench test. The test results show that the oil pressure, flow and velocity of engine lubrication system are all in the appropriate ranges, In the transient process of the lubrication system, conver-gence of the oil pressure wave, as well as oil pressure stability are good. In addition, the lubrication system has an i-deal matching and adaptive abilities in the temperature range from 90 C to 140 'C.
摘要：介绍了主油道油压反馈控制的汽油机新型润滑系统。在稳态仿真计算中，对比分析了正常工况(90℃)和极限工况（(140C)下各管路润滑油的压力、流量和流动速度。以正常工况下发动机3500r/min升至4500r/min的加速过程为例，进行了瞬态特性的仿真。并用机油泵的性能试验和发动机台架试验进行验证。试验结果表明；发动机油压、流量、流速均在合理的范图内；润滑系统在瞬态过程中压力波动收效性好，油压稳定性较高；机油温度在90～ 140℃时，系统有理想的匹配适应性。
