Summary:

The analysis of engine's performance, gas emissions and combustion parameters is critical in the development of internal combustion engines. The combustion parameters analysis provide important information to speed up real-time engine's operation in order to shorter the process of engine's map calibration. The real-time analysis of these parameters allows the detection of anomalies, such as the prediction of knocking event.From the measurement of the In-cylinder pressure curve and the use of a one-zone combustion model is possible to evaluate the heat release rate, mass burned fraction and average In-cylinder gas temperature. Aiming to expand the amount of real-time data available, such as unburned and burned gases temperature and volume, radius and velocity of turbulent spherical flame and turbulence factor, this paper presents a hybrid combustion model, being composed by coupling a two-zone model to a one-zone model.Using the proposed model, a combustion analysis of the Ford Sigma 1.6L is presented. The tests realized showed that the proposed model has an excellent performance, since it promotes a better understanding of the combustion process in real-time and reduces the post-processing time of the combustion parameters
