Significant efforts have been made in internal combustion engine development to meet the most restrictive emission regulations. Analysis of in-cylinder pressure-time history is one of the most powerful tools to address combustion chamber design and engine calibration. This analysis provides information about load, knock occurrence and intensity, combustion phasing, combustion duration, shape of heat release rate curve and mass fraction burned. Aiming at an efficient real-time monitoring of combustion and engine performance, a processing framework was proposed. The proposed framework seeks to balance parameters accuracy with computational cost. For this, the number of points used on each parameter calculation is reduced by splitting the processing into two paths of data detailing and partitioning. Also, to reduce additional expenses with supplementary hardware, thermodynamics methods were applied to use only the in-cylinder pressure data.
