一、气缸头的表面测温对于表面测温,大都是采用热电偶来进行的。但是,用热电偶测量壁面温度,由于被测表面沿热电偶有热量导出,破坏了被测表面的温度场,使热电偶测得的温度实际上是温度场破坏以后的表面温度,因此,就产生了测量误差。 First, the cylinder head surface temperature measurement For the surface temperature, mostly used to carry out the thermocouple. However, with the thermocouple to measure the wall temperature, as the measured surface along the thermocouple has the heat, destroying the temperature field of the measured surface, so that the temperature measured by the thermocouple is actually the temperature field after the destruction of the surface temperature, so Produced a measurement error.
