1¡¢ Motorcycle igniter
The function of the motorcycle igniter is to receive and store the ignition voltage provided by the magneto, accurately calculate the ignition time, and timely provide it to the high-voltage package. The high-voltage package inducts the low-voltage electricity of the igniter and supplies the spark plug ignition for the high-voltage electricity. In short, it is the device to start the motorcycle.
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.
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. Ignition coil: converts 12V low voltage electricity provided by automobile power supply into high voltage electricity that can break through spark plug electrode gap.
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.
Ignition switch: control the on-off of low-voltage circuit of ignition system, control the start-up and shutdown of generator.
Spark plug: introduce high voltage electricity into combustion chamber to produce electric spark to ignite mixture.
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.
2¡¢ High pressure package
High voltage pack, also known as line output transformer, also known as line pack or line transformer. The working principle of high voltage pack of display is basically the same as that of TV. Its main function is to generate anode high voltage and provide various voltages such as focusing, acceleration and grid.
Due to the working conditions of high temperature, high frequency, high voltage and high current, and the influence of external environment humidity or dust, the damage probability of high voltage package is high. After rectifying the alternating current output from the high-voltage package, a high-voltage electric field with the positive electrode in front can be established. Electrons are accelerated in this electric field, and the image has enough brightness. This is the working principle of how to discharge the high voltage package.
