Numerical investigation the multi-process IC engine working cycle parameteres, on the basis of the experimental data

Abstract

In the paper was conducted numerical investigation of the multi-process IC engine working cycle. It was created a three-dimensional model of the IC engine working space, which by geometrical parameters corresponds to the real test engine, used during the experimental work. As the boundary conditions, were used the experimental data, measured during the experimental work. By application of the CFD analysis, it was simulated the working cycle of the multi-process IC engine, and were determinate the main working parameters (cylinder pressure, cylinder temperature, indicating efficiency, combustion law...). All results are compared and verified with the experimental data, obtained from the experimental investigation conducted on the test engine in the laboratory. At the end it was determined the error of numerically obtained results, relate to the experimental ones.
