The Optimization Design Studying on Crankcase Ventilation System
Taking the problem of crankcase ventilation system of one three-cylinder turbocharged gaso-line engine as an example,the research of optimizing the design of crankcase ventilation system was car-ried out,including the analysis of limit assembly,structural comparison of parts,engine bench function verification,and vehicle performance.Ultimately,the crankcase pressure fluctuation and noise in idle condition of the vehicle were improved,and the crankcase ventilation system was optimized.
