Specification

Sensor with amplifier and power supply for determining top dead canter position. The TDC system consists of the TDC sensor with integrated TDC signal amplifier and TDC power supply. It is used for the dynamic determination of the top dead center position (TDC) in piston engines.

Knowledge of the exact top dead canter is of great importance for investigating processes occurring inside engines, since all measurements are recorded against crank angle and with respect to TDC. With some thermodynamic quantities such as average indicated pressure, a deviation of only 0.1° crank angle from the true top dead location already results in an error of several percentage points in the pmi value.
