Abstract

Preventing cycle-by-cycle variations of combustion in gasoline engine is necessary for further improvements in thermal efficiency. In this paper, Large-Eddy Simulation (LES) of combustion in a gasoline engine was conducted with compressible fluid engine CFD code HINOCA, which is based on Cartesian grid and immersed boundary method. Prediction accuracy was verified, and influence factors of cycle-by-cycle combustion variations were analyzed with the obtained results.
