Ignition system - petrol models
The ignition system is united with system of injection of fuel, and make a uniform control system of the engine (address to the Head of the Power supply system and release more in detail). Depending on model, there are two possible types of system of ignition.
System with the distributor (engine E7J)
Engine E7J is equipped by the distributor; besides, the ignition system includes the module-amplifier, one coil of ignition, the gauge of speed/position коленвала and the detonation gauge.
System without the distributor (engines K7M, F3R and F7R)
Engines K7M, F3R and F7R are equipped by system of ignition without the distributor which copes ECU, and consists simply of two ВВ coils of ignition, the gauge of speed/position коленвала and the detonation gauge. Each coil of ignition serves two cylinders (one feeds spark plugs of cylinders №1 and №4, and another - cylinders №2 and №3). Ignition coils work by a principle of "a single spark”, that is the spark in spark plugs slips twice for each cycle of the engine, on a step of compression and on a release step. The electronic module of management uses signals from various gauges, calculating the demanded moment of ignition and time of a food of the coil of ignition. Functioning of the gauge of a detonation is described above - pay attention that on engines F3R it is established on a head of the block of cylinders.
To prevent damage of components of system of ignition and to reduce risk of reception of a trauma, it is necessary to observe following precautions.
