Abstract
In-cylinder pressure measurements are one of the most important tools for investigating the internal process in internal combustion engine. The correct position of TDC (Top Dead Center) is of crucial important in calculating IMEP or heat release rate. Since the calculation of these values are very sensitive to error in TDC determination. In this paper, the method of the correction of the position of the TDC was presented and was used to correct the position of TDC of the two types marine diesel engines.
