Numerical modeling of IC engine combustion process

Abstract

Experimental research generally requires time and money. For this reason, numerical simulations are increasingly being applied. A numerical modelling of the IC engine working cycle from the moment of intake valve is closing until the exhaust valve opening is performed in this paper. The maximum pressure value obtained by the experiment was selected as the control parameter of the simulation accuracy. 3D model of the engine cylinder is created in the software package Ansys, which according to the dimensions and compression ratio corresponds to the experimental. The boundary conditions obtained by the experiment were applied to the created model. Based on the results, it was found that the maximum pressure value is very close to experimental.
