| 摘 要： | 在发动机瞬态工况下，试验研究了排气质量流量、过量空气系数的阶跃幅值和周期对三效催化转换器动态特性的影响规律．试验结果表明，排气质量流量、过量空气系数的阶跃幅值和周期对三效催化转换器活性层中铈（Ce）表面氧气吸附和脱附存储能力（OSC）、排放影响显著．稀混合气向浓混合气阶跃后，排气质量流量增加，出口过量空气系数在理论混合...

| Abstract: | Dynamic response of three-way catalytic converter with different exhaust mass flows,inlet amplitude and period was analyzed experimentally under transient conditions.Results show that engine emissions and oxygen storage capacity(OSC)of three-way catalytic converter with Ceria(Ce)catalyst on the washcoat is affected by exhaust mass flow,amplitude and period of inlet excess air ratio.When exhaust mass flow increases,emissions decrease at the beginning and turn deteriorated at some mass flow,and duration of ou... |
