Introduction to the composition of silicon nitride igniters
The relationship between the power supply voltage used by the silicon nitride igniter and the matching high-voltage film is as follows.
AC CDI igniter and back pressure AC igniter use the principle of capacity saving electricity "silicon instantaneous discharge, and the high-voltage package outputs ultra-high voltage. Using the AC pulse high-voltage power output by the magneto (called AC-CDI igniter) is suitable for simultaneous use 2. The DC CDI igniter uses a 12V battery as the power source in the car. The igniter has a boost module circuit inside, and then uses the "storage capacitor" silicon discharge circuit mode to output the high voltage package. It is ultra-high voltage. Because we use a low-voltage DC system power supply, it can be called a DC-CDI igniter, and the output terminal contains some common CDI high-voltage packages. 3. The DC inductive igniter uses the 12V battery in the car as the power supply, and ignites According to the internal calculation system circuit, the high-current/low-voltage signal is output as a special software package and an inductive high-voltage package, a large part of which can be called a "digital electronic igniter". The output of this electronic igniter is the same as the inductive high-voltage package Or the power supply time is "charging", and when the inductive high-voltage package is powered off, it is "ignition". The ignition working principle of applying traditional capacitors to discharge the high-voltage system on the CDI igniter is different. 4. The integrated control igniter refers to the igniter The igniter combined with the high-pressure gun has a similar shape to the high-pressure gun. Only the AC igniter on the market is powered by Magneto. The AX100 integrated control igniter used for Li Chong’s engine, the integrated electronic igniter of Mulan Culture, and the self-triggering AC-CDI igniter, with some variable angle functions in China. The insecticidal engine has an XH90 integrated igniter, and the sensor needs to provide a trigger signal, which is a positive AC-CDI circuit. 5. But check the identification of the high-voltage pack: the primary of the ordinary CDI high-voltage pack The temperature of the research resistance is about 0.3 euros, which is suitable for electric pulses of 150~250V. The inductive high voltage package of modern motorcycles has a primary resistance of about 3~4 euros, which is divided into anodes and is suitable for working at a voltage of 9~12V. The spark is slightly stronger than a normal CDI igniter.Ignition circuits using inductance are more complex.
The silicon nitride igniter is mainly composed of a power supply, ignition control coil, distributor, ignition system switch, spark plug, additional and resistance and short connection technology devices, high and low voltage equipment wires, etc.
1. The silicon nitride igniter power supply is composed of a battery and a generator. When starting, the ignition system is supplied with low voltage power from the battery. When the generator voltage is higher than the battery voltage after starting, the ignition system will provide low-voltage power from the generator.
2. The ignition coil converts the 12V low-voltage system power provided by the car's power management into high-voltage power that can penetrate the gap between the working electrodes of the spark plug.
3. Driven by the distributor camshaft, the current of the ignition coil is cut off in time, so that the ignition coil generates high voltage in time, and transmits the high voltage to the sparks of each cylinder according to the ignition sequence. At the same time, the ignition time can be adjusted automatically and artificially. The function of the capacitor is to reduce the flame of the circuit breaker contacts and increase the auxiliary voltage of the ignition coil. 4. Ignition system switch: Control the on-end of the low-voltage working circuit of the ignition system, control and start and close the generator.
5. Spark plug: Introduce high-voltage electricity into the combustion chamber to generate spark ignition mixture.
6. Add a resistance short-circuit device. When the system starts, the additional resistance is short-circuited, and the primary working current of the ignition coil increases, and the jump energy of the spark can be increased during start-up.
