| Abstract | ||
| In the present work, an approach to estimate of flow characteristic in inlet and exhaust manifolds of internal combustion engines is performed using a four-stroke variable compression ratio single cylinder gasoline engine. In the theoretical part a computer simulations of the flow field in the intake and exhaust systems as well as the cylinder cavity for the experimental data obtained in the gas exchange cycle program using the method of characteristics for the engine dimensions and timings used in the experimental study as well as the data obtained from the gas exchange cycle program for the sake of comparison and presentation of flow characteristic. In the experimental work, the compression ratio was varied from 7 to 11 at variable speed with constant throttle opening, where engine performance was obtained. Results of engine performance as well as pressure, temperature and velocity fields in the intake and exhaust systems obtained by the gas exchange cycle program using the method of characteristics are presented. | ||
