Claim 1:
2. The spark plug heat rating measurement method of claim 1, wherein: the spark plug is installed in a constant-temperature water jacket cooling chamber, and a constant spark discharge current control module is connected to a high-voltage terminal of the spark plug; the constant spark discharge current control module provides the constant controllable spark discharge current to the spark plug to heat up the high-voltage central electrode through the high temperature of the spark plasma channel; during the discharge process, a real-time controller dynamically adjusts the spark discharge current of the constant spark discharge current control module, based on a discharge current amplitude provided by a DC sensor, and the temperatures of the high-voltage central electrode and the surrounding ceramic insulator measured by a temperature measurement module, to control the temperature of the spark plasma channel and provide a required spark energy to heat up the central electrode of the spark plug.
