Study on Error of Temperature Measurement from Thermocouple about High Temperature Combustion Gas in Cylinder of the Engine
Author(s):

Journal: VEHICLE ENGINE

Keyword:  内燃机热电偶温度测试测量误差;
Abstract: 根据发动机气缸内高温燃气温度静态和动态的不同情况,对热电偶测头和热电偶套管在静态下的辐射热损失以及动态响应过程进行了推导与计算.结果表明,静态情况下热电偶读数误差增加幅度较小,动态响应过程中热电偶读数误差主要决定于热电偶测头及热电偶套菅的辐射热损失,且其辐射热损失又受热电偶测头的滞后时间常数τ0的限制.
