Description

technical field [0001] The invention relates to the technical field of electronic monitoring of internal combustion engines, in particular to an inductively powered internal combustion engine piston monitoring system. Background technique [0002] As a stable and reliable power source, the internal combustion engine is widely used in vehicles and ships; the piston of the internal combustion engine is the core of the power output part (module) of the internal combustion engine, and it is also one of the most demanding parts of the internal combustion engine. In the working environment, it not only needs to withstand Large external pressure, mechanical load, and huge heat load due to the heat transfer of high-temperature gas will cause the mechanical performance of the internal combustion engine piston to decline, and the top is prone to ablation and cracking, thereby reducing the service life of the engine. Therefore, the monitoring of different performance parameters of pist...
