The system of ignition makes ignition of a fuel mix in engine cylinders at some point depending on engine and loading turns. On cars many various types of systems of ignition are established.
The system of ignition eats from an onboard network of the car. In the ignition coil tension of an onboard network of the car will be transformed to a high voltage. The high voltage is used for formation of a spark between electrodes of spark plugs in engine cylinders in a compression step. The chain of a low voltage, or primary chain, consists of electroconducting which connects the accumulator, the ignition lock, primary winding of the coil of ignition, the breaker and the condenser. The chain of a high voltage, or a secondary chain, consists of a high-voltage winding of the coil of ignition, the central high-voltage wire, the distributor of ignition, a rotor of the distributor, high-voltage wires of spark plugs and spark plugs.
The coil of ignition will transform a faltering current of a low voltage (+12 In) to a high-tension current for breakdown of an air gap between electrodes of spark plugs. The coil of ignition represents the transformer with opened magnitoprovody which consists of the internal core and external ring магнитопровода. The secondary winding having a large number of rounds, is reeled up round the core. Primary winding with smaller number of rounds is reeled up over the secondary.
The system of ignition works as follows. When giving tension on primary winding of the coil of ignition in the coil of ignition there is a magnetic field. For inclusion and switching off of the tension submitted to primary winding of the coil of ignition, the electronic block is used.
At tension switching off on primary winding of the coil of ignition power failure of a magnetic field in a secondary winding generates a high voltage which via the distributor of ignition moves to a candle of the corresponding cylinder. Then tension again moves to primary winding of the coil of ignition therefore the magnetic field increases and the cycle repeats for giving of a high voltage to the following spark plug.
The corner of an advancing of ignition is set by the distributor and corrected centrifugal and vacuum by regulators. The centrifugal regulator consists of two грузиков which at increase in turns of the engine under the influence of centrifugal force disperse from a distributor shaft. Dispersing, грузики turn a cogwheel concerning a distributor shaft, and the ignition moment depending on engine turns thus is corrected. The divergence size грузиков is defined by effort of returnable springs.
The vacuum regulator fixed on the case of the distributor of ignition, consists of the diaphragm block. To one party of a diaphragm depression from the carburetor moves through a hose. Other party of a diaphragm is connected by draft with the ignition distributor. Under the influence of depression the diaphragm is bent and through draft turns a basic plate against the direction of rotation of a shaft of the distributor and as a result it the corner of an advancing of ignition depending on engine loading is corrected.
At works on electric system not to damage semi-conductor devices (diodes and transistors), is necessary to fulfill the following requirements:
– in operating time of the engine do not disconnect the accumulator, the generator of an alternating current or any electric sockets;
– at carrying out any works remove the negative plug from the accumulator;
– at carrying out electrowelding works on the car disconnect the generator of an alternating current and the electronic control device;
– do not allow operation of the engine with the generator disconnected from electric system;
– do not check operability of the generator, closing its target contacts on weight.
