Numerical investigation of IC engine multiprocess work

Abstract

In order for the experimental work to be successful, it is necessary a serious preparation, as well as time for experimental work execution. Also, experimental work is usually demands high costs for equipment, materials and engaged people. However, one is for sure, the experimental work cannot be replaced, but the numerical approach can be a good tool, at least for the first stages of the product development, in order to reduce the experimental work costs. In the paper was performed numerical investigation, of the IC engine muliprocess work. The obtained results, were compared with the experimental ones. How the numerical investigation was used to simulate the IC engine working cycle, as the control parameters were taken the indicating parameters. By comparing with the experimental data, it was found that the maximal error is less than 3.5%. This means that the numerical approach gives a satisfying results, and as such can be used for further investigations.
