General description and operation of the ignition system

The ignition system of the petrol engine is designed to ignite the fuel-air mixture in the combustion chambers of the cylinders.

Elements of the ignition system on a 2.0-liter engine (with fuel injection Simos)
Fig. 210. Elements of the ignition system on a 2.0-liter engine (with fuel injection Simos): 1 - HV wire to the spark plug; 2 - plug suppressing interference; 3 - a protective cover; 4 - a cover of the distributor of ignition; 5 - Rotor, distributor; 6 - three-prong plug connector; 7 - dust cover; 8 - the ignition distributor with Hall sensor; 9 - O-shaped sealing ring; 10 - presser rail; 11 - a bolt, 25 Nm; 12 - a spark plug 30 Nm; 13 - a tip of the HV wire on the spark plug; 14 - bolt 20 Nm; 15 - knock sensor (G61); 16 - high-voltage transformer (152 N); 17 - the output stage of the high voltage transformer (N157); 18 - terminal "15"; 19 - terminal "1"

Elements of system of ignition engine VR6 (with system of injection Motronic)
Fig. 211. Elements of the ignition system on the engine VR6 (with system of injection Motronic): 1 - trehkontaknaya plug connector (black) for the Hall sensor; 2 - the gauge of the Hall; 3 - bolt 10 Nm; 4 - a guide wire HV high voltage transformer; 5 - spacer ring; 6 - five-pin plug connector to the high voltage transformer; 7 - plug suppressing interference; 8 - high voltage transformer; 9 - knock sensor plug connector; 10 - a cover of a camshaft drive mechanism; 11 - bolt 20 Nm; 12 - the gauge of a detonation II, on the suction side; 13 - drive the Hall sensor; 14 - bolt 100 Nm; 15 - knock sensor l, on the downstream side; 16 - a spark plug 25 Nm; 17 - O-shaped sealing ring; 18 - spark plug

At the 2.0-liter engine ignition system (Fig. 210) is part of a combined injection and ignition system Simos, while the VR6 engine ignition system (Fig. 211) is part of an integrated system Motronic.
Combining injection and ignition systems in a single electronic system has the following advantages:
- Combining the functions of units and sensors can reduce their number;
- Ignition and carburetion processes are optimized together with the improved torque characteristics, fuel consumption, exhaust gas composition, easier starting and warming up a cold engine;
- Greater opportunities for other functions:
- Management of an automatic transmission;
- Management of traction control;
- Management of an antilock braking system;
- Controlled air-conditioning, anti-theft device, etc.
Ignition systems have no moving parts and therefore do not require maintenance. They do not have adjustments as fully electronic ignition control ECU and implemented using the mode information of the engine obtained by the engine control system's sensors.
