The physically-mathematically model for studying the thermal regime of the spark ignition engine concerning the filling coefficient

The study of the development conditions of the intake process from spark plug engine, especially from thermal point of view, highlight complex influences. These influences affect in a decisive manner the energy performance of the engine. In this paper, the authors had done a study and an analysis of the aspects for the purpose to develop a physically-mathematically model which ensures the highlighting of the thermal regime influences of the spark plug engine concerning the efficiency of the filling.
