The ignition system is used forprocess of ignition of the fuel-air mixture. Its main purpose is to convert a low-voltage current into a high-voltage one. This is necessary to create a powerful spark at the ends of the candle electrodes. The voltage on the electrode must be at least 20 thousand volts. Ignition systems are divided into three types:
1) contact - the appearance of pulses to feedhigh-voltage current is carried out by opening the contacts of the ignition distributor. At this point, the coil generates a high-voltage current and transfers it to the distributor.
2) contactless - differs from contactreplacing the breaker with a similar one, only with the absence of a contact group. Pulses are created by the switch. BSZ promotes a more complete combustion of the mixture, fuel economy and increased torque. This is due to an increase in the voltage to 30 thousand volts.
3) the microprocessor-distributor system in it is replaced by an ignition module that monitors the moment of the pulse and creates a high-voltage current.
1) Power source - battery or generatorcar. It all depends on what stage the engine is at. If the engine is at the start-up stage, the source is the battery. If the engine is already running and turns the generator, then the energy is produced last.
2) The power switch is an ignition switch or a special button that turns on the power and sends it to the system elements, or turns it off.
3) Energy storage device - is an element that, after accumulating energy, gives it out for sparking, or an element that is capable of converting a current.
4) Ignition distributor - used to direct the high voltage current to the required spark plug, depending on the position of the engine crankshaft.
Ignition module.Quite often it is used in injector cars and does not directly connect to the engine's camshaft. This decision is quite common. Systems that use the ignition module are called static, that is, fixed. Structurally, this device replaces several elements of the KSZ. The ignition module consists of two coils having a certain capacity, and switches.
5) Ignition wires - solid conductors, which are used to transport high voltage current from the distributor to the candles.
The principle of operation of any of the above systemsis the transmission of a high-voltage current that is generated by a coil or ignition module, through a distributor to a specific plug. The spark on the candle electrodes should appear at the time of the compression phase in the engine cylinder.
