Abstract
Dual-fuel engines using a low cetane number primary fuel such as natural gas (NG) ignited by a pilot distillate spray have been in existence for a considerable period. However, there are still many unknowns related to the fundamentals of the combustion process of the two fuels. This article reports on the development of a simulation model of the dual-fuel combustion process calibrated using constant-volume combustion bomb tests, the bomb being specifically developed for this application. Both global and local variations in the combustion process are studied parametrically.
