摘　　要：λ传感器广泛地用于汽车尾气检测和控制。在发动机台架上对自制λ传感器进行了性能测试 ,并用气体化学平衡原理对浓、稀燃烧状态的输出电动势进行了解释 ,同时探讨了温度对输出电动势的影响。所得到的理论模型与测试结果相一致。sensors have been applied to monitor and control exhaust in automobile industry. The prepared sensors were tested in engine bench to gain essential function of sensors. Chemical balance theory was introduced to explain electromotive force of the sensors and the influence of temperature on the signals. The educed theoretical model of electromotive force well agrees with testing results.
