| Abstract: | Based on Rompe-Weizel formula for the spark resistance and plug stray capacitance parameter, an equivalent secondary coil capacitive discharge circuit of an automotive was established, and the noise spark current level caused was obtained by the capacitive discharge when the plug gap was breakdown. Effects of the plug dimension, magnitude and location of the resistor, and the gap breakdown voltage on the spark current level were studied. This work done here is useful to research the automotive Electromagnetic Compatibility, interference and the deterioration effects of ignition noise on various electronic systems. |
