The numerical investigation of the combustion process of the dual fuel IC engine

Abstract

In the paper it was conducted the numerical analysis of the combustion process. In order of this it was created 3D model of the IC engine working space, which by geometry do not correspond to no one existing engine. The simulation it was conducted for the entire workingcycle, that is, for all four strokes and for the combustion process, by application of computational fluid dynamics. In the simulation it was defined that the engine is turbocharged, and that uses two fuels, gasoline and methanol. According to the conducted analysis, as well as to the obtained results, it was found, that is necessary provide more intensive combustion, in order to increase the indicating efficiency. In order to provide this, were proposed actions for future researches, such are the earlier ignition, redesign of the shape of the combustion chamber and increment of the compression ratio.
