Development of the calculation method of factors of a working cycle of the engine with combined mixture formation and compression ignition

The analysis of modern methods of factors calculation of a working cycle of an internal combustion engine is considered in the paper. It allows to draw a conclusion that the model of heat calculation of Grineveckiy – Mazing is maximally close to a real process occurring in the cylinder of the engine, and it gives a good accuracy in results at engineering calculation. It is offered a technique to calculate factors of a working cycle of the engine with combined mixture formation and compression ignition. Some discrepancies between calculated and experimental data are revealed. They are caused by the fact that the calculation model does not take into account particularities of a working process of the engine with combined mixture formation. It is necessary to conduct an additional experimental investigationin order to eliminate the revealed discrepancies.
