“…The analysis of liquid dynamics and optimization design First of all, using conventional non-linear bearing connection for rapid calculation got the main bearing load changing with engine speeds, as shown in figure 4. From that, the fourth main bearing load at 4000r/min is max, therefore, convert the fourth main bearings to EHD bearing and take the detailed friction calculation under this speed [5]. The optimization scheme is also based on crankshaft speed for 4000 r/min on the fourth main bearing.…”

To a particular inline-four high-speed gasoline engine as the research object, main bearing lubrication analysis model of four-cylinder engine is based on AVL-Excite Power Unit software and couples the mechanical dynamics with lubricating fluid dynamics. On the basis of this model, we are focusing on the influence of parameters such as grease groove width on the engine main bearing lubrication performance. According to the analysis of simulation results on the minimum film thickness and maximum film pressure, and combined with the analysis report of disassembling the engine, it is easy to know why bearing bushes wear and provide the basis for the optimized design of the crankshaft main bearing. Improving design of the main bearing is more useful for operating requirement.
