[0003] The temperature test of the combustion chamber parts of the marine low-speed engine mainly includes the hardness plug method, the fusible alloy method, the linkage transmission mechanism method, and the wireless telemetry method. The online display of the space temperature field cloud map and the temperature gradient are not enough, and in the test system formed by the above method, no special temperature field sensing test piece with the combustion chamber parts of the marine low-speed engine has been developed, which can directly reflect the piston and cylinder liner of the marine low-speed engine. , The integrity and correlation of temperature field distribution during cylinder head and exhaust valve operation are not enough, and the efficiency of temperature field test data analysis is low
