二次补气阀的技术要求和试验方法

Technical Requirements and Test Methods of Secondary Gulp Valve

二次补气阀是摩托车发动机排放净化的关键零部件之一,通过单向进气阀从外界吸入空气到排气管内,为氧化催化剂的高效工作补充氧含量,通过调整设定单向进气阀的金属簧片厚度、簧片止口和开口区面积等参数,可控制补气量的大小。

Gulp valve is one of the key parts for motorcycle engine emission control. The air induced from the ambience can go into the exhaust pipe through the one-way valve, which helps to supplement the oxygen content. And the gulp capacity can be controlled by adjusting and setting the metal reed thickness, reed closing and opening areas of the one-way intake valve.
