Date Sep. 5, 1991.In order to determine the course of a varying internal pressure in the cylinder of a piston-type internal combustion engine using measurement sensors which are in interaction with the outside of the cylinder; an acceleration, velocity or displacement signal (X(t)) is produced and a transfer function (H( omega )) between the internal pressure (Y(t)) and the acceleration, velocity or displacement signal (X(t)) is determined once and thereafter an output signal representing the internal pressure is derived only from the acceleration, velocity or displacement signal X(t)) and the transfer function. |
