在分析气缸盖温度场分布的基础上，利用电火花加工机加工了有缺陷的内气缸盖。根据发动机的实际工况，建立了一个专用的热电偶传感器检测气缸盖内缺陷的实验平台。结果表明，安装在气缸盖上的热电偶传感器能够直接检测出气缸盖的缺陷，尤其是靠近缺陷位置的2点和8点，为进一步监测气缸盖的热状态提供了有效的方法。
Under Analyzing temperature field distribution of cylinder head, the flaw inner cylinder head was machined on electric discharge machine. According to engine practical working condition, a special experimental platform was set up to detect flaw inner cylinder head by using thermocouple sensor. The results showed thermocouple sensors fixed in cylinder head can directly detect flaw, especially on point 2 and point 8, which were near the flaw position, and can provide effective method for further monitoring thermal condition of cylinder head.
