2.7.7.29. Detonation sensor

The sensor of a detonation is installed on the block of cylinders. The sensor perceives the vibrations of walls of the block of cylinders arising at a detonation. The piezoelectric element of the sensor will transform this vibration pressure to tension signal. The control unit of the engine uses this signal for suppression of a detonation by moving of a corner of an advancing of ignition towards delay.
