An alternative fuel such as natural gas may be used in a dual-fuel engine for both economic reasons and emission advantages. However, the performance at relatively light load and idling conditions has been quite poor, while at very high load, engine knock is often encountered. In this study, a three-dimensional, dual-fuel, in-cylinder model has now been developed. This is used to provide an improved understanding of the operational features arising from the interaction between the gaseous fuel and the pilot fuel, the preignition processes, and subsequent combustion of the pilot fuel and gas during the piston movement.
