Abstract
火花塞的中心电极采用伞骨形、半球形或球形结构,两个环形侧电极在通电后与中心电极、金属壳体形成三级跳火。又因点火范围大,间隙稳定,从而使燃料得到充分燃烧,减少了积炭,稳定了放电电压,改善了点火性能,进一步加长了使用寿命。
Description
所属技术领域
本实用新型涉及一种汽油机火花塞。
背景技术
火花塞是汽油机的点火装置,是利用其中心电极和侧电极的跳火间隙在一定电压的作用下产生跳火,形成“火花”以完成汽油机点火,但其跳火范围有限,当电极积碳或电压不稳时都可能使跳火失败,使汽油机不能正常起动。
发明内容
本实用新型提供一种新型跳火结构的火花塞。
附图说明
通过以下附图对本实用新型作进一步说明:
图1中;火花塞的金属壳体3内套瓷绝缘体2,并通过密封垫圈6进行密封,接线螺杆1通过密封剂4与新型中心电极7相连,两个环形侧电极8与新型中心电极7、金属壳体3形成三级跳火结构,异形密封圈5装于金属壳体3的螺纹末端,用于火花塞与汽油机的安装密封。
具体实施方式
火花塞的中心电极采用伞骨形、半球形或球形结构,两个环形侧电极在通电后与中心电极、金属壳体形成三级跳火。
又因点火范围大,间隙稳定,从而使燃料得到充分燃烧,减少了积碳,稳定了放电电压,改善了点火性能,进一步加长了使用寿命。
