PRODUCT INTRODUCTION

Car spark plug test principle

In an automobile ignition system, the high-voltage ignition coil generates a high voltage, and the spark plug diverts it from the high-tension ignition coil into the engine cylinder. The spark between the spark plug electrodes will ignite the mixture. The detector could tell the good spark plugs from the bad by the strength of the spark.
