The crankcase ventilation system is a very important part of the internal combustion engine but not so much attention is usually paid on what happens in the crankcase. A lot of information is available on what happens in the combustion chamber but not so many papers have been published related to the crankcase ventilation. Actually, efficiency improvements can be obtained with an optimization of the crankcase ventilation system and so fuel can be saved and the overall emissions of carbon dioxide reduced. The present is a thesis describing the work done by the author in his internship with Chrysler LLC during the Joint Master Degree program between Politecnico di Torino and University of Windsor. The work is aimed to simulate the crankcase ventilation system of Pentastar V6 3.6L engine with a 1D/CFD software to see possible ways of improvement and provide some baseline guidance in the initial selection of design parameters for future engines.
