As turbo-charged gasoline engines are getting more popular and general, engine lubrication becomes more important in terms of engine development because turbo-charged gasoline engines have the complicated oil line than naturally aspirated engines. In this study, the lubrication system analysis (1D CFD) was conducted with AMESim to suggest oil pump capacity and engine idle speed on lubrication system by investigating component pressure. The oil pump analysis (3D CFD) was conducted with Pumplinx to optimize oil pump performance by evaluating flow irregularity and performance of oil pump including volumetric efficiency and cavitation. Analysis result shows that the flow irregularity was improved by 39% and the volumetric efficiency by 3% at low engine speed. In addition, the averaged friction torque was reduced by 2.1% at entire engine speed. And also shows that predicted pressure of component have the averaged 5.9% tolerance in comparison with rig test result. Engine lubrication analysis using 1D, 3D simulation tool is helpful to engine development and can provide essential information of lubrication design to engineer at initial phase.
