Numerical analysis of the engine with spark ignition and compression ignition

摘要: The article presents simulation researches on the combustion process in four-cylinder testing engine, based spark ignition engine Toyota Yaris 1, 3 dm3 which was equipped with two systems of power supply i.e.: fundamental and ignition. Two methods initiating were applied: by and, after it turned off, means dose injection. aimed at revealing differences performance, above all changes pressure that occurred cylinder for kind two-fuel engine. injected into equal to about 5 ÷ 8 % general mass fuel supplied approach collector determined remaining part, direct injection took place over several dozen rotation degrees crankshaft before TDC (Top Dead Centre). A spatial grid engine’s model (pre- processor) prepared, also a modification source KIVA 3V program made consisting taking account It is necessary mention standard contains, as default, only one
