摘要
大气压力在内燃机性能试验中是至关重要的。文中分析了大气压力测量中相关的测量元件的性能及其测量精度。采用扩散硅绝对压力传感器作为内燃机性能试验中的大气压力测量的敏感元件。提出了温度漂移的解决措施。
It is very important to measure atmospheric presure in the performance test of engine. The property and the measurement precision of sensor on atmospheric presure was analysed. The absolute presure sensor of diffuse silicon was adopted as atmospheric presure measurement in the engine test. A method to solve temperature drift was developed. Automatic measurement of atmospheric presure was realized.
