Abstract

The roads are getting more and more crowded everywhere. As a consequence, the pollution by exhaust gasses produced by the growing number of vehicles also increases. People are searching for ways of reducing automotive pollution. Alternative fuels can be found, one way. Probably the most common tool for converting liquid and gas fuel into useful mechanical work is the internal combustion (IC) unit. The explanation for its well-accepted efficiency, economics, longevity, controllability and other competitive alternatives can be explained by its general appearance. NOx and suot formation is due to the heterogeneous non-premixed combustion of high local temperatures and the local oxygen shortage in the traditional direct injection diesel powered engine. The adjustment to the combustion cycle to boost engine output is an alternative to rising engine efficiency and reducing engine emissions. A simulation software with CFD code was implemented in this context. The cold flow of the working conditions for HCCI engine control by creating a comprehensive model. Furthermore, the use of the in-cylinder model potential for cold flow simulation in the SI engine has been demonstrated. All strokes are replicated, pulling, compressing, expansion and exhaust. The Discrete Phase System is used for injecting, evaporating and boiling water.
