一种二次补气阀的阀体
本技术涉及摩托车发动机
,特别是涉及一种二次补气阀的阀体。
技术介绍
传统的摩托车发动机在点燃压缩混合气做功后还有部分混合气并没有完全燃烧,而是经过排气管排放到大气里面,这样既浪费了汽油燃料还产生了较大的空气污染物。为解决该问题,现在出现了一种发动机二次燃烧系统,即设置补气系统,在靠近发动机缸头的排气口位置处设置二次补气口,并在二次补气口处安装二次补气阀;二次补气阀能将新鲜的空气直接输入到高温的排气中,促使废气中的HC和CO在排气系统内氧化为水和二氧化碳,从而改善排放。现有一种二次补气阀,其包括有阀体和安装在阀体内部的簧片,簧片的两侧分别设置进气管和出气管,出气管连通排气管,簧片处于复位状态时,簧片隔开进气管和出气管,当排气管产生负压时,大气压推开簧片,空气经进气管和出气管后进入到排气管内;这种补气阀的阀体结构简单,生产制造方便,但是难以给发动机排气管提供精确定量的新鲜空气,很容易出现空气补充过多和过少的问题,补充过多的空气将降低排气管的温度影响有害气体的再次氧化,而空气的补充量过少有害气体的氧化又不彻底,转化效果不理想。
技术实现思路
为了克服现有技术的不足,本技术提供了一种能够给排气管提供精确定量空气的二次补气阀的阀体。本技术解决其技术问题所采用的技术方案是:一种二次补气阀的阀体,所述阀体上设置有进气室、补气室和控制室,所述阀体内部设置有连通所述补气室的导流腔,所述进气室设置有连通所述导流腔的进气孔,所述控制室正对所述进气孔的位置设置有连通所述导流腔的安装孔;所述阀体上形成有密闭盖安装面,所述控制室的外侧端口设置在所述密闭盖安装 ...
