Features of the device and the principle of operation of the ignition system (Kalina 1118)

The vehicle's ignition system does not use a traditional distributor. A four-terminal ignition coil is used here, consisting of two two-terminal ignition coils combined into one unit. The current in the primary windings of the ignition coils is controlled by a controller that receives information from sensors and uses two powerful transistor valves.

The ignition system has no moving parts, so it does not require maintenance and does not require adjustments.

The ignition system uses a spark distribution method called the "idle" spark method. The engine cylinders are paired 1-4 and 2-3, spark formation occurs simultaneously in two cylinders: in the cylinder in which the compression stroke ends (working spark), and in the cylinder in which the exhaust stroke occurs (idle spark).

Due to the constant direction of current in the windings of the ignition coils, the spark current for one spark plug always flows from the central electrode to the side electrode, and for the second - from the side electrode to the central electrode.

The ignition system uses A17DVRM spark plugs or their foreign analogues. The controller controls the ignition in the system. The crankshaft position sensor supplies the controller with a reference signal, based on which the controller calculates the firing sequence of the coils in the ignition module. To precisely control the ignition, the controller uses the following information:
