| Abstract: | A mathematical model of spray and combustion processes in diesel engine was presented in this paper. It was used in a three dimension numerical program developed by author. A spray equation, which was formulated from a droplet distribution function, was solved to describe the spray dynamics including droplet collision and breakup. A single step Arrhenius type reaction was used to model the overall engine combustion process. The significance of the combustion model in this situation is mainly to appropriately account for the energy release. Using this program the spray and combustion processes in cylinder of diesel engine were practically calculated for three types of combustion chambers in ZH1105 engine. The calculated values, compared with the test results, show that the program can simulate the processes of spray and combustion in diesel engine. |
