SIMULATION OF CYCLE-BY-CYCLE VARIABILITY OF SI ENGINE

Original language description

This paper deals with utilization of an adaptive combustion model in order to simulate cycle-by-cycle variability of SI engine. The empirical adaptive combustion model consists of two parts: the first part for ignition delay prediction and the second part for in-cylinder combustion process description. There is proved mutual independence of these two phases that are generally given by normal distribution in terms of cycle-by-cycle variability. The practical utilization of the cycle-by-cycle variability simulation is demonstrated by computational analysis of different variability levels at chosen engine part load. There is shown particular benefit in fuel consumption through the reducing cycle-by-cycle variability of the combustion process.
