description: In this paper, using GT-SUITE program pack the computational research on piston rings was performed in axisymmetrical setting, plane piston ring cross section movement in piston groove and 0-dimensional piston crevice gas flow. Compression rings dimensions effect on engine blow-by and ring stability in its groove was investigated based on 6 combinations of dimensions in the whole gasoline naturally aspiratedÂ  engine working range. Obtained results show that engine blow-by has significant dependence on first compression ring sealing quality. The highest outbreak happens during radial flutter at compression and expansion strokes. Lowering first ring mass and axial thickness helps narrowing radial flutter occuring range. It is also noticed, that second compression ring influence on engine blow-by is insignificant. The inputs for modelling piston rings were also obtained by using GT-SUITE. The combustion cycle in 37 points with aid of corrected Wiebe combustion model and iteratively combustion chamber wall temperatures have been solved.
