Simulation and Optimization of the Combustion Process of Diesel Engine

Abstract:

In order to improve the performance of the diesel engine, the original engine fuel injection advance angle is optimized, and a new advance angle of fuel injection is proposed in this paper. By numerical calculation with simulation of software FIRE, the effect of different combustion chamber structures on the cylinder pressure, temperature, accumulated heat release and the parameters such as NOx mass fraction was analyzed. From the simulation results, the optimized fuel injection advance angle had greatly improved the diesel combustion and emission performance. Finally, via experimental verification, the engine with optimized fuel injection advance angle has better dynamic performance, as well as less emission than original machine.
