三效催化转化器 meaning in English
twc three way catalytic converter
Examples
- In the study , the performance of dual - bed three - way catalytic converters of conventional structure and with deflector are compared by numerical simulation and experiment
在研究过程中，采用数值模拟和试验相结合的方法比较了常规结构和带有弥散器结构双载体三效催化转化器的性能。 - This a / f controller could quickly response and regulate the lpg injection time to meet different engine running conditions and make excessive air coefficient ( a ) in normal operation range of the three - way ca alyst system ( twc )
该控制器能根据不同的工况快速反应并调整燃料喷射占空比，使过量空气系数符合三效催化转化器有效工作范围( = 1 0 . 005 ) 。 - According to its configuration , the monolith is considered to be a porous media . based on the monolith model and the use of software fluent , the research on the light - off characteristic and conversion efficiency of three - way catalytic converter is processed
在所建催化转化器模型的基础上,根据载体具有分布细小孔道的特点,将其作为多孔介质处理,利用fluent软件,对冷起动阶段三效催化转化器的起燃特性和转化效率作了数值模拟。 - Relative to euro , euro emission regulations add the test of emission in 40s after cold - start . in order to meet the more strict emission regulations , the key question is how to make the three - way catalytic converter to light - off and increase the conversion efficiency . so it is necessary to do a numerical simulation on light - off characteristic and conversion efficiency of three - way catalytic converter in cold - start stage
欧排放标准相对于欧排放标准增加了冷起动头40s的有害排放物测试,为满足更严格的排放法规,如何使三效催化转化器尽快起燃,提高对排气的转化效率是关键问题,因此对三效催化转化器在发动机冷起动阶段的起燃特性和转化效率进行数值模拟研究是大势所趋。 - ( 5 ) " electronic controlled bypassing air + three - way catalytic converter " system used for carburetor petrol engine which " is capable of setting up working condition for three - way catalytic converter and can solve the contradiction between emission control ( controlling hc , co , nox at same time ) and power , torque , fuel consumption having been put forward
( 5 )建立了针对化油器式车辆的“电控补气+三效催化转化器”系统，通过采用双回路电控补气可以为三效催化转化器建立良好的工作条件，较好的解决了化油器式汽油机动力性、排放(同时降低hc 、 co和nox )之间的矛盾。
