15.2. System of ignition of EZL
The system of ignition of EZL includes spark plugs, high-voltage wires, the ignition distributor, the coil of ignition and the electronic control ECU device together with sensors, executive mechanisms and electric wires. The principle of action of system of ignition identical irrespective of an arrangement of knots and elements of system of ignition depending on car model.
The control unit of ignition gives tension on primary winding of the coil of ignition. At the required moment the control unit disconnects tension from the ignition coil that leads to falling of magnetic field in primary winding and induces high voltage in a secondary winding of the coil of ignition. High-voltage tension at some point from the ignition coil via the distributor of ignition and high-voltage wires moves to a certain spark plug. At receipt of high voltage on a spark plug between electrodes of a spark plug the spark which sets fire to fuel-air mix in the engine cylinder is formed. Definition of the moment of firing of fuel-air mix is carried out by the electronic control device.
Definition of a corner of an advancing of ignition and its constant adjustment is carried out by the electronic control device (ECU) on the basis of information on engine turns, the provision of a bent shaft and depression in an inlet collector received from the sensors installed on the engine. Also when determining a corner of an advancing of ignition information on the provision of a butterfly valve (acts from the switch of extreme provisions of a butterfly valve), to air temperature, coming to the engine and temperature of cooling liquid is considered.
Depending on the advancing of ignition applied like fuel an initial corner it is possible to change the switching cap placed in a motor compartment near the ECU block.
