Event: JSAE Spring Meeting
It is known that swirl and tumble effects are strengthening charge motions within cylinder, and in consequence, improve combustion stabilities through stratifying the mixture of a perimeter of the spark plug as well as intensifying the mixing of air and fuel. In this study, enhanced charge motions were induced by a gasket type port masking scheme with a variety of shapes and ratios. The purpose of this investigation is to analyze the effects of intake flow motions on combustion phenomena and characteristics of cyclic THC and NOx exhaust emissions with various intake openings in CVVT system.
