Search of malfunctions
The detonation ignition arising in case the moment of ignition it is established with too big advancing, harms to the engine. Its consequence are an overheat, damages of bearings and pistons.
Function of adjustment of a detonation
Combustion in cylinders is supervised by a so-called sensor of a detonation which is screwed at the left on the engine block. Two sensors are established in engines with working volume of 1,8 l (at the left on the block) and in six-cylinder engines (on the right and at the left above on the block).
There is a following: at receipt of a signal «detonation combustion at the last ignition» cylinders following on turn continue to receive the moment of ignition calculated for them. But in that cylinder where the detonation was established, the moment of ignition moves approximately on 3 ° back. As it is noticed above, it occurs only in one cylinder. In others the moment of ignition calculated originally remains.
The slice is inserted into this sensitive element «пьезокерамики», a material which we well know on gas pyezozazhigalka. Mechanical forces (stretching, pressure), operating on пьезокерамику, will be transformed by it to electric tension.
