Abstract: This paper deals with an application of advanced simulation methods to the modelling of Duel-Fuelled engines (Hydrogen/Diesel) in which the premixed Hydrogen gas is ignited by the combustion flame initiated by a diesel spray. The model consists of a diesel auto-ignition model and a modified combustion model. The influence of main engine parameters i.e., injection advance, and various percentages of mixing of hydrogen with diesel on rate of heat release, flame propagation and NO_x formation has been investigated. Experimental results were compared with modelled values. Computational Fluid Dynamics (CFD) analysis was carried out and limitations of the model were studied.

Keywords: dual fuel engines; hydrogen; diesel; modelling; simulation; CFD analysis; computational fluid dynamics; premixed combustion; emission analysis; vehicle emissions; auto-ignition models; combustion models; heat release; flame propagation.
