Nowadays combustion models come up to the requirements of engineers. Numerical simulations show good agreement with experimental results of the compression ignition (CI) and spark ignition (SI) engines. Controlled auto-ignition (CAI) has emerged as one of the most promising engine technologies with the potential to combine fuel efficiency and improved emissions performance. Despite considerable advantages controlling the combustion is still an area of on-going research. The combustion models used for engine simulations are not well prepared and they have to be validated with experimental data. In this paper the first step of setting up of the combustion model is presented with the use of experimental results from three different rapid compression machine (RCM) experiments. That kind of work has to be performed before real engine calculations, to give the brief view on the differences in the experimental and simulation data. Also during this work an improved thermodynamic database for the ECFM-3Z combustion model in the FIRE software was introduced.
