secondary air injection tube

In order to strengthen emission controlling of the carburetor motorcycle engines,the metering characteristics of carburetor are adjusted,combustion chamber as well as intake and exhaust ducts are further optimized,and secondary air injection system and oxidation type catalytic converter.

为此,通过化油器燃油供给特性的调整及燃烧室与进排气道结构优化,采用二次空气喷射系统和催化转化器,运用曲轴箱闭式通风装置减低曲轴箱窜气污染物,将现行生产的各种化油器式中小排量摩托车排气污染物控制在GB14622-2002排放限值内,实现摩托车发动机排放控制的强化。

In order to enhance the air compensating effect of the secondary air injection system, a model for a motorcycle engine is set up and the performances of the model JS125-12A are calculated and analyzed by using the engine performance analyzing software package of AVL BOOST.

为了提高二次空气喷射系统的补气效果,建立了摩托车发动机模型,应用内燃机性能分析软件AVLBOOST,对JS125-12A型摩托车发动机进行性能计算,并与试验值进行了对比分析。
