G070033 CFD Analysis of Combustion Process for Natural-gas Dual-fuel Engine with Double Pilot injections

Abstract

A combustion process of the natural-gas dual-fuel engine is simulated using CFD with a combustion model taking account of a mixing process. Here, the special attention is focused on the effects of double-pilot injection condition on the combustion process. The result shows that the tendencies of incylinder pressure histories agree with that measured by the experiments. Furthermore, details of the combustion process of a double-injection condition are discussed.
