Attention! Since there is high voltage in the ignition system, be especially careful when working with it. This applies not only to the amplifier, coil, distributor and spark plugs, but also to plug caps, tachometer and other equipment.
1. The ignition system has full control over the timing. The computer of the engine management system determines the optimal advance, taking into account the speed and temperature of the engine, the position of the throttle valve and the vacuum in the intake manifold. These parameters are fed to the ECU input using the appropriate sensors. The ignition timing during engine start and warm-up, as well as at idle, is determined by separate algorithms.
Ignition systems with distributor
2. The distributor ignition system is installed on all models of production until 1990. The system includes an ignition coil, a distributor, an ignition control unit, candles and high-voltage wires. The distributor of ignition is given but rotation from a camshaft.
3. The location of the system elements depends on the model, year of manufacture, engine and transmission types. On some 4-cylinder models, the ignition coil and control box are inside the distributor, while on other models, the coil and control box are located outside the distributor in the engine compartment. There are models on which the coil is located separately in the engine compartment, and the ignition control unit is integral with the ECU. On all V-engine models, the coil and ignition control unit are located inside the distributor.
Ignition systems without distributor
4. On production models since 1998, an ignition system without a distributor is installed. The system includes an ignition coil pack directly connected to all spark plugs/
