Abstract

One of the systems has a decisive effect on the quality of combustion process, as well as the performance of diesel as the fuel supply system. Thus, the study aims to make fuel system works best, most optimal; always get the attention of researchers worldwide. KIVA calculation and simulation software, was developed many years at Los Alamos National Laboratory (Los Alamos National Laboratory - LANL), USA, is the CFD simulation software for 2D and 3D fluid flow turbulence with rays spray, chemical reactions such as combustion simulation of combustion engines. KIVA3V the computer program used to simulate the process of internal combustion engines in general and the fuel injection, combustion of diesel fuel in particular. This paper presents the results of the KIVA software application to find out the optimum value of injection timing at which the parameters of power, fuel consumption rate, gas is the most logical and consistent Experimental matching engine. This is one of the advanced researches in internal combustion engines. In particular, studies of combustion of biodiesel fuel for diesel engines.
