    Abstract: Using the flowmaster software, this paper established the 1D numerical simulation for the lubrication system of a gasoline engine, simulating the operation of the engine lubrication system according to different design prop. Based on the research on the lubrication system, its operating status of the lubrication system is simulated under different design plan. According to the assessment on the calculated pressures in the all sites of the engine lubrication system, a design plan is determined.
