Abstract

A numerical study on effects of the injection direction of the pilot diesel fuel on combustion and emissions under two-stroke dual-fuel marine engine-like conditions is presented in this paper. It is found that the injection direction of the pilot fuel has significant effects on the methane start of combustion as well as flame propagation direction which leads to different heat transfer trends to combustion chamber walls and flamewall interaction. Furthermore, the injection direction of
the pilot fuel changes the methane combustion intensity which leads to different trends for emission formation.
