چکیده:

In this study, the effect of the initial charge temperature on the second law terms under the various injection timing in direct injection spark ignition hydrogen fuelled engine has been performed theoretically during compression, combustion and expansion processes of the engine cycle. The first law analysis is done by usingthe results of a three dimensional CFD code. The results show a good agreement with the experimental data. Also for the second law analysis, a developed in house computational code is applied. It was obtained that initial charge temperature and fuel injection timing have considerable effect on the variation of the second law terms and irreversibilities.
