Abstract: 

In this study, performance of oil droplet separator in crankcase ventilation system for three engines, Ford-Ecoboost (impactor with variable area), Nissan-vq37de (inertial impactor), and Peugeot-Xu7 (cyclone) at the same volumetric flow rate has been studied experimentally. Because of the complexities of geometrical and functional in internal combustion engines, a test rig is designed to study the separation of engine oil droplets with a diameter of 0.1 to 10 mm of gas leakage (blow-by), in this experiment, a special oil atomizer implemented for the production of micro droplets, similar to the drops in engine blow-by. Tests were done in two volumetric flow rate 16 and 24 L/min. To ensure the accuracy of the results of designed test rig, all the tests were repeated at least three times for each volumetric flow rate. Gravimetric method was implemented to estimate the separation efficiency. According to the results of the tests it was found that the separation efficiency of impactor with variable area is better than similar models, so that at the same flow rate of two phase air-oil flow, efficiency of impactor with variable area is almost eight times that of similar models. In this article, pressure drops of flow of the mentioned separators were also measured experimentally. Although the efficiency of impactor with variable area is more than the other impactors but its pressure drop is lower than Nissan’s impactor.
