摘　　要：本文通过在某汽油发动机缸盖总成上布置停缸系统,在缸盖上布置停缸油道,设计停缸油道支架、凸轮轴、摇臂、挺柱和电磁阀,在台架上实现停缸功能,测试响应时间、气门升程、凸轮轴扭矩等,进行台架耐久试验,总结规律,为新发动机开发提供技术储备。By applying CDA system on head assembly of one gasoline engine,Layout CDA oil gallery on cylinder head,design CDA oil gallery bracket,camshaft,RFF,HLA(Hydraulic Lash Adjuster)and OCV(Oil Control Valve),CDA function is achieved on dyno,measure response time,valve lift,camshaft torque,etc.,carry out dyno durability test,summarizes the rule,provide technical reserve for new engine development.

关 键 词：摇臂 停缸 缸盖总成
