    2. When measuring the magneto performance parameter , we find that the instrument which use to measure voltage and current is still the simple voltmeter and amperemeter in the national standard , and the form of wave that we observed is anomaly. based on the measure principles, it obviously ca n ' t be used to do quantitative analysis ; because the discharge process of ignition system is quite complex, accompanies with very strong electromagnetism interference, and the ignition current and voltage are variable , it make the measure of ignition energy become a difficult thing of ignition system performance detection
