In the present work there have been shown the results of initial researches concerning heat release process in the spark ignition engine with inner catalyst. There has been presented the calculative model of heat release process and calculative methodology leading to obtaining temperature course, combustion function and its derivative because of measured course of combustion pressure. The pressure courses, which are necessary for calculations, were obtained on the measure seat with AD 1600 engine that is load with eddy- current brake. The engine was equipped with spark plug with miniature pressure sensor f-my Kistler, and the courses of pressure were recorded by the use of f-my Smetec apparatus. The courses of heat release process were analysed in rotations of n=1500 rotations/min and n=3000 rotations/minute and load of 50 Nm and 70 Nm. The analysis was made comparatively for the system with the catalyst and without catalyst. In the work there have been presented the results of experimental and model researches which aim was the analysis of the issue of influencing the catalytic active surfaces placed in the spark ignition engine combustion space. Those surfaces, catalysing the process of creating combustible mixture and its combustion, influence the combustion process course and, simultaneously, have impact on the engine work parameters and the heat release course.
