The EZL ignition system includes spark plugs, high voltage wires, ignition distributor, ignition coil and ECU electronic control unit along with sensors, actuators and electrical wires. The principle of operation of the ignition system is the same regardless of the location of the components and elements of the ignition system, depending on the model of the car.
The ignition control unit supplies voltage to the primary winding of the ignition coil. At the required moment, the control unit disconnects the voltage from the ignition coil, which leads to a drop in the magnetic field in the primary winding and induces a high voltage in the secondary winding of the ignition coil. High-voltage voltage at a certain moment from the ignition coil through the ignition distributor and high-voltage wires is supplied to a specific spark plug. When high voltage is applied to the spark plug, a spark forms between the electrodes of the spark plug, which ignites the fuel-air mixture in the engine cylinder. The determination of the moment of ignition of the fuel-air mixture is carried out by an electronic control device.
Determination of the ignition timing and its constant adjustment is carried out by an electronic control device (ECU) based on information about engine speed, crankshaft position and vacuum in the intake manifold obtained from sensors installed on the engine. Also, when determining the ignition timing, information about the position of the throttle is taken into account (removed from the throttle limit switch), the temperature of the air entering the engine and the temperature of the coolant.
Depending on the type of fuel used, the initial ignition timing can be changed with a switch plug located in the engine compartment next to the ECU.
