Abstract: A spark plug heating method based on transient control of a spark discharge current. By accurately controlling discharge current energy, a high-voltage electrode is heated by using a discharge current to heat a spark plug from the inside of a spark plug; by accurately controlling the spark discharge current energy and duration, and measuring the temperature changes of the high-voltage electrodes and ceramic bodies of different spark plugs at the same time, the heat value range of the spark plugs is determined; by means of the heating and temperature control of the central electrode of the spark plug and the nearby ceramic body, the controllable and active heating of the central electrode of the spark plug is implemented, and by actively heating the spark plug, the temperature of the high-voltage electrode of the spark plug and the nearby ceramic surface is increased to an appropriate temperature range, thereby effectively preventing and cleaning carbon deposits on the surface of the spark plug. In the present invention, by actively heating the spark plug and controlling the temperature within a more appropriate range, the carbon deposits on the surface of the spark plug can be effectively prevented and cleaned, and the heat value range of the spark plug can be determined at the same time.
