WanKel转子发动机对火花塞结构提出了新的要求,因此贝鲁公司研制了一种新的火花塞。从外表来看,新的250/18G2型火花塞与一般的火花塞没有显著区别,其绝缘体系由导热的高绝缘Rubinit陶瓷所构成,具有高机械强度和耐高温性。Rubinit陶瓷含有95%的氧化铝,热稳定性良好。在绝缘体中有一个中心电极,用精炼银制成,其导热性极为良好。精炼银对于燃烧气体的学侵蚀特别稳定,而且电蚀损耗极小。银电极和螺杆是用电介铜连接的。新型火花塞采用锥形密封面以代替常用的密封垫圈。因
WanKel rotor engine spark plug structure put forward new requirements, so Beirut company developed a new spark plug. In appearance, the new 250 / 18G2 spark plugs are not significantly different from the general spark plugs, the insulation system of the high thermal insulation Insulating Rubinit ceramic composition, with high mechanical strength and high temperature resistance. Rubinit ceramic contains 95% alumina, good thermal stability. In the insulator there is a center electrode, made of refined silver, and its thermal conductivity is very good. Refined silver combustion gas combustion is particularly stable, and minimal erosion loss. Silver electrode and screw is connected with a dielectric copper. The new spark plug uses a tapered sealing surface instead of the usual gaskets. because
