1、 The function is to boost the low-voltage DC current to sufficient high voltage according to the working sequence of the engine (ignition sequence). Ignite the compressed high-temperature and high-pressure combustible mixture through the spark plug of each cylinder to complete the work process.
2、 The ignition system consists of battery, ignition switch, ignition coil, ignition control module, high-voltage wire, spark plug, etc.
3、 According to the control mode of primary circuit, the ignition system is divided into:
1. Traditional ignition system traditional ignition system is mainly composed of power supply (battery and generator), ignition switch, ignition coil, capacitor, breaker, distributor, spark plug, damping resistance and high-voltage wire. Working principle: turn on the ignition switch and the engine starts to run. The cam of the circuit breaker rotates continuously to make the contact of the circuit breaker open and close continuously. When the breaker contact is closed, the current of the battery starts from the positive pole of the battery and flows back to the negative pole of the battery through the ignition switch, the primary winding of the ignition coil, the movable contact arm of the breaker, the contact and the distributor housing. When the contact of the circuit breaker is pushed open by the cam, the primary circuit is cut off, the current in the primary winding of the ignition coil rapidly drops to zero, and the magnetic field around the coil and in the iron core also rapidly attenuates or disappears. Therefore, induced voltage is generated in the secondary winding of the ignition coil, which is called secondary voltage. The current passing through is called secondary current, and the circuit through which the secondary current flows is called secondary circuit. After contact disconnection, the higher the decline rate of primary current, the greater the change rate of magnetic flux in the core, and the higher the induced voltage generated in the secondary winding, the easier it is to break through the spark plug gap. When the magnetic flux in the core of the ignition coil changes, high voltage (mutual inductance voltage) is generated not only in the secondary winding, but also in the primary winding. When the contact is separated and the primary current drops, the direction of the self induced current is the same as that of the original primary current, and its voltage is as high as 300V. It will break through the contact gap and produce strong electric sparks between the contacts, which not only makes the contacts oxidize and ablate rapidly and affects the normal operation of the breaker, but also reduces the change rate of the primary current, the induced voltage in the secondary winding and the spark in the spark plug gap, so that it is difficult to ignite the mixture. In order to eliminate the adverse effects of self induced voltage and current, a capacitor C1 is connected in parallel between the breaker contacts. At the moment of contact separation, the self induced current charges the capacitor, which can reduce the spark between contacts, accelerate the attenuation of primary current and magnetic flux, and increase the secondary voltage.
