Abstract

火花塞的中心电极采用铂金丝,在火花塞瓷绝缘体烧制过程中放入其内孔,利用瓷绝缘体的收缩,使其烧制完成后铂金丝与瓷绝缘体有足够的密封,又因铂金腐蚀极小,电极间隙变化小,从而稳定了放电电压,改善了点火性能,进一步加长了使用寿命。

Description

火花塞
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以完成汽油机点火,其密封都采用密封剂高温烧结来实现,但其效果一直以来不是很好,以至使用寿命受到限制。
发明内容
本实用新型提供一种新型结构的中心电极,能很好地克服原有密封性能的不足。
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4内套瓷绝缘体2,并通过密封垫圈6进行密封,连接棒3将铂金丝中心电极7和接线螺杆1直接相连,铂金点8与铂金丝中心电极7形成跳火间隙,异形密封圈5装于金属壳体4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铂金丝,在火花塞瓷绝缘体烧制过程中放入其内孔,利用瓷绝缘体的收缩,使其烧制完成后铂金丝与瓷绝缘体有足够的密封。
又因铂金腐蚀极小,电极间隙变化小,从而稳定了放电电压,改善了点火性能,进一步加长了使用寿命。

Claims (1)

1.火花塞其特征为:火花塞的中心电极为铂金丝,侧极为向内折弯结构,罩住铂金丝,形成跳火间隙,同时也包括侧极上有铂金丝。
