Analysis of Plastic Oil-Gas Separator for Diesel Engine Valve Chamber Cover

Three different configurations of plastic oil-gas separator for diesel engine valve chamber cover were studied using numerical simulations. The distribution of flow velocity, pressure and oil droplets collection from simulation results were assessed to find out an optimum design for the oil-gas separator. Further, the oil-gas separation efficiency from simulation and experimental test was also reviewed to verify the simulation model as well as selection of the best design amongst the considered three configurations of the oil-gas separator.
