EFFICIENCY OF A NEW IC ENGINE CONCEPT WITH VARIABLE PISTON MOTION

Abstract

This paper presents simulation of working process in a new IC engine concept. The ain feature of this new IC engine concept is the realization of variable movement of he piston. With this unconventional piston movement it is easy to provide variable ompression ratio, variable displacement and combustion during constant volume. hese advantages over standard piston mechanism are achieved through synthesis of he two pairs of non-circular gears. Presented mechanism is designed to obtain a pecific motion law which provides better fuel consumption of IC engines. For this aper Ricardo/WAVE software was used, which provides a fully integrated treatment f time-dependent fluid dynamics and thermodynamics by means of onedimensional ormulation. The results obtained herein include the efficiency characteristic of this ew heat engine concept. The results show that combustion during constant volume, ariable compression ratio and variable displacement have significant impact on mprovement of fuel consumption.
