Folksvagen Sharan/Sharan repair>> Ignition system>> The general description and work of system of ignition
The system of ignition of the petrol engine is intended for gas mixture ignition in chambers of combustion of cylinders.

Fig. 210. Elements of system of ignition on the 2,0-litre engine (with system of injection Simos): 1 — wire ВН, to a spark plug; 2 — the tip suppressing a radio noise; 3 — a protective cover; 4 — a cover of the distributor of ignition; 5 — бегунок the ignition distributor; 6 — three-contact штекерная колодка; 7 — a dustproof cover; 8 — the distributor of ignition with the Hall gauge; 9 — an O-shaped sealing ring; 10 — clamping рейка; 11 — a bolt, 25 Нм; 12 — a spark plug, 30 Нм; 13 — a tip of wire ВН, on a spark plug; 14 — a bolt, 20 Нм; 15 — the detonation gauge (G61); 16 — the high voltage transformer (N 152); 17 — the target cascade of the transformer of a high voltage (N157); 18 — the plug 15; 19 — the plug 1



Fig. 211. Elements of system of ignition on engine VR6 (with system of injection Motronic): 1 — трехконтакная штекерная колодка (black colour), for the Hall gauge; 2 — the Hall gauge; 3 — a bolt, 10 Нм; 4 — directing wires ВН, to the high voltage transformer; 5 — распорное a ring; 6 — five-contact штекерная колодка, to the high voltage transformer; 7 — the tip suppressing a radio noise; 8 — the high voltage transformer; 9 — штекерная колодка the detonation gauge; 10 — a cover приводного the camshaft mechanism; 11 — a bolt, 20 Нм; 12 — the gauge detonations II, on the soaking up party; 13 — a disk of the gauge of the Hall; 14 — a bolt, 100 Нм; 15 — the detonation gauge l, on the release party; 16 — a spark plug, 25 Нм; 17 — an O-shaped sealing ring; 18 — a spark plug tip




At the 2,0-litre engine ignition system (fig. 210) is included into incorporated system of injection and ignition Simos, and at engine VR6 ignition system (fig. 211) is included into incorporated system Motronic.
Association of system of injection and ignition in uniform electronic system has following advantages:
- Combination of functions of units and gauges allows to reduce their number;
- Processes of ignition and смесеобразования are optimised in common, characteristics of a twisting moment, the expense of fuel, structure OG thus improve, start-up and warming up of the cold engine is facilitated;
- The big possibilities for performance of other functions open:
- Management of an automatic transmission;
- Management противобуксовочной system;
- Management of antiblocking brake system;
- Management of the conditioner, the antijoy ride device, etc.
Systems of ignition have no mobile details and consequently do not demand service. They do not have adjustments as management of ignition completely electronic and is carried out ЭБУ, using the information on the power setting, received from gauges of a control system by the engine.
