Spark plug heat rating measurement method and system based on spark discharge current active heating
Patent number: 11923663Abstract: In the spark plug heat rating measurement method and system based on spark discharge current active heating, the spark plug is installed in a constant-temperature water jacket cooling chamber with a specific torque. A constant spark discharge current control module is connected to the high-voltage terminal of the spark plug, to provide real-time controlled discharge current to heat up the high-voltage central electrode of the spark plug. During the spark discharge process, the temperature change of the high-voltage central electrode and the surrounding ceramic insulator are measured by a temperature detection module and used to determine the heat rating of the spark plug. By real time adjusting the discharge current level of the spark plug, or providing a same amount of spark energy to the spark gap, the heat ratings of spark plugs with different ceramic insulation structures can be evaluated through the temperature changes during discharge or after discharge.Type: GrantFiled: July 22, 2021Date of Patent: March 5, 2024Assignee: WEICHAI TORCH TECHNOLOGY CO., LTD.Inventors: Ming Zheng, Guangyun Chen, Xiao Yu, Tangliang Zhang, Jin Qian, Hua Zhu -
