...individual ignition coils are used here.
The ignition system has no moving parts, so it is maintenance-free and does not require adjustments.
The ignition system uses spark plugs of the AU17DVRM type or their foreign analogues (see appendix 5).
In the ignition system, the ECU monitors the distribution and moment of spark generation in the cylinders. Spark generation occurs sequentially in those cylinders in which the compression stroke ends and, accordingly, the order 1–3–4–2 is observed. The crankshaft and camshaft position sensors send pulse "reference" signals to the ECU, on the basis of which the ECU calculates the sequence of operation of the ignition coils. To precisely control the ignition, the ECU uses the following information:
- crankshaft speed;
- engine load (mass air flow);
- coolant temperature;
- crankshaft position;
- camshaft position;
- presence of detonation.
