Piston – Top Dead Centre

The Top Dead Centre of the cylinder movement is measured for adjustment of the precise ignition point in engine development. In doing so, a miniature eddy current sensor is integrated in the cylinder head cover. From this position, it precisely measures when the piston is at the smallest distance from the sensor. The ignition is optimum at precisely this time. Earlier or later ignition would reduce the efficiency of the engine. This measurement is only possible in towing operation.
