Basic composition of igniter
Hits：1658 Date：2021-6-1
The composition of motorcycle igniter is mainly composed of power supply, ignition coil, distributor, ignition switch, spark plug, additional resistance and its short-circuit device, high and low voltage wire, etc.
1. Power supply: composed of battery and generator. When starting, the ignition system is provided with low-voltage electric energy by the battery; After starting, when the generator voltage is higher than the battery voltage, the ignition system is provided with low-voltage electric energy by the generator.
2. Ignition coil: converts 12V low voltage electricity provided by automobile power supply into high voltage electricity that can break through spark plug electrode gap.
3. Distributor: under the drive of generator camshaft, switch on and cut off the primary current of ignition coil on time, so that the ignition coil can generate high-voltage electricity in time, and transmit the high-voltage electricity to each cylinder spark plug according to the ignition sequence; At the same time, the ignition time can be adjusted automatically and artificially. The function of capacitor is to reduce the contact spark of breaker and increase the secondary voltage of ignition coil.
4. Ignition switch: control the on-off of low-voltage circuit of ignition system, control the start-up and shutdown of generator.
5. Spark plug: introduce high voltage electricity into combustion chamber to produce electric spark to ignite mixture.
6. Short circuit device of additional resistance: short circuit the additional resistance during starting to increase the primary current of ignition coil and increase the jumping energy of spark plug during starting.
