Introduction (problem statement and relevance). This article provides up-to-date information analysis of the crankcase gases bypass effect from the crankcase ventilation system to the compression ignition engine intake. The paper considers the information on the variants of the crankcase ventilation systems of modern engines. The article reveals the necessity to analyze the engine working process at the design and development stage of a closed crankcase ventilation system. The legislative requirements for the implementation of the ventilation system to ensure safe environmental performance have been indicated. The purpose of the study was to assess both open and closed ventilation system effect on the crankcase space indicators, in particular, on the average specific fuel consumption, with reference to a high-performance automobile engine with compression ignition.Methodology and research methods. Theoretical and computational studies were carried out with the help of mathematical statistics and thermodynamics methods in a one-dimensional setting. The verification of the calculations reliability was carried out by comparing the simulation data and the results the internal combustion engine experimental studies.Scientific novelty and results. A thermodynamic model of a high-performance automobile engine compression ignition V8 CHN 12/13 with an open and closed ventilation system of the crankcase space has been developed. The model made it possible to evaluate the effect of crankcase gases bypass back to the engine cylinder intake.Practical significance. The developed thermodynamic models confirmed the insignificant effect on the working process of the V8 CHN 12/13 engine by bypassing crankcase gases back to the cylinder inlet.
