6.1.2. System of ignition
The system of ignition generates an ignition spark which ignites fuel-air mix. For this purpose in ignition coils tension of the rechargeable battery of 12 V will be transformed to tension of 30 000 Century.The system of ignition of the petrol engine is a component of a control system of the engine. The moment of ignition is defined by a control system of the engine. At the same time the monitor the engine is based in the field of characteristics of ignition and in addition uses signals of various sensors. Synchronization of system of ignition is reached by the signals arriving from Hall's sensor or the pulse sensor on distributive or cranked to an engine shaft.
Anti-detonation regulation ensures economic functioning of the engine with high extent of compression. For this purpose detonation sensors transmit signals to the monitor the engine which if necessary displaces the ignition moment in the direction "late".
System of direct ignition
Distribution of high voltage of ignition on separate spark plugs happens electronic elements which are replacement to the mechanical distributor of ignition.
Elements of system of ignition do not wear out and do not demand service. Replacements in the course of maintenance demand only a spark plug.
During the work with electronic system of ignition for avoidance of traumatizing people or damages of the system it is necessary to observe the security measures stated at the beginning of this Chapter.
Arrangement of coils of ignition:
Engines to 125 h.p.: The system of ignition has on 2 candles on one coil. Both coils of ignition are fixed together in one case on a head of cylinders. At the engine of 1.8 l / 125 h.p. and the engine of 1.6 l in addition in the case of coils of ignition the powerful output cascade is located.
Engines with a turbocompressor of 1.8 l: 4 coils of ignition are located directly on spark plugs.
