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