Abstract

二冲程汽油机节油器,由挡销(1)、弹簧(2)、壳体 (3)、阀门(4)、固定座(5)和垫圈(6)组成,并通过固定 座(5)安装在汽油机曲轴箱的进气口上。
该节油器能防止二冲程汽油机的所谓倒喷现象, 达到节油的效果。

Description

本实用新型涉及一种二冲程汽油机节油器,特别是安装在汽油机进气口的节油器。
目前,摩托车汽油机采用的活塞阀结构简单,利用活塞裙部作密封效果好。其缺点是当活塞由上止点开始向下运行时,进气口还没有关闭,造成曲轴箱内的部分混合气体从进气口排出来,即产生倒喷现象,造成燃料的浪费。
本实用新型的目的在于提供一种能防止倒喷现象,从而达到节能效果的二冲程汽油机节能器。
本实用新型由挡销(1)、弹簧(2)、壳体(3)、阀门(4)、固定座(5)和垫圈(6)组成,通过固定座(5)安装在汽油机曲轴箱的进气口上。固定座(5)的中心有通气孔,壳体(3)的中心也有通气孔,通气孔就是进气口与曲轴箱之间的通道。壳体(3)为两个圆柱体组成的凸状结构。所述的壳体(3)的一头(大头)与固定座(5)连接,另一头(小头)中心咽部有固定阀门的座,阀门(4)通过弹簧(2)、挡销(1)和垫圈(6)固定在阀门座上。工作时,由阀门(4)控制进气口与曲轴箱的通断。
本实用新型解决了二冲程活塞式汽油机的倒喷问题,根据实验表明,节油率达20%以上。
图1为本实用新型主视图;
图2为图1的左视图。
图中(1)-挡销,(2)-弹簧,(3)-壳体,(4)-阀门,(5)-固定座,(6)-垫圈,A-进气口,B-出气口,C-气腔通道。
下面结合附图和工作过程作进一步的说明。当发动机未启动时,阀门(4)在弹簧的作用下处于关闭状态。启动时,由于活塞上行到上止点前时进气口打开,这时曲轴箱容积变大,混合气体由A进气口被吸入,推动阀门(4)打开,气体进入通道C腔,经B出口进入曲轴箱,当活塞到达上止点时,曲轴箱内的压力与外界压力相等,阀门(4)在弹簧(2)的作用下而关闭。这时,活塞由上止点向下运行,此时进气口还没有关闭,使已吸进的气体向外排出,经B口进入C腔,此时阀门(4)已关闭,使被排出的气体困在C腔,防止了倒喷。
