1. Can produce enough spark plug gap breakdown voltage
Spark plug and spark breakdown voltage required when called breakdown voltage. Secondary voltage generated by the Ignition Module must be higher than the breakdown voltage, in order to make the spark plug arcing. Breakdown voltage of the size of the affected by many factors, including the following:
(1) spark plug electrode gap and the shape of the
The greater the spark plug electrode gap, the higher the breakdown voltage;
Angular electrode tip, the required breakdown voltage is low.
(2) gas mixture within the cylinder pressure and temperature
The greater the pressure of the mixture, the lower the temperature, the higher the breakdown voltage,
(3) the temperature of the electrode
The higher the temperature of the spark plug electrodes, the smaller the gas density around the electrode, the lower the breakdown voltage.
2. Sparks should have enough energy
Engine work, due to the temperature of the mixture near the end of its compression ignition temperature, only need 1 ~ 5mJ spark energy. However, in the mixture too thick or too thin, the engine start, idle or open throttle rapidly, you need a higher spark energy. And with the economy and the modern engine exhaust purification requirements increase, there is a pressing need to improve the Ignition Module energy. Therefore, in order to ensure reliable ignition, high-energy electronic Ignition Module generally should be 80 ~ 100mJ of spark energy to start the spark should be generated higher than 100mJ energy.
3. The engine ignition timing should be adapted to work
First, should the engine Ignition Module sequence of work. Second, we must in the most favorable moment for ignition.
As the mixture in the combustion cylinder take some time, so the mixture should not be only on the compression stroke at the Ignition Module point, but should be sufficiently in advance so that the piston reached TDC, the combustion gas mixture has been, so that the engine be higher power. Ignition time is generally used to indicate the ignition advance angle, from the beginning to the piston reaches the spark issued only on the period of time up to that point turned the crank angle.
