In the paper the application of three calculation methods for approximation of engine combustion pressure curves and their 1st and 2nd derivatives on the basis of discrete data obtained from an electronic indicator, was presented and discussed by using example calculations. In the considered cases all the three methods practically ensured adequate approximation accuracy at nodes.
