在如何提高火花塞的工作质量方面有多种方法,但是其中最重要的一个问题还没有得到解决,那就是火花塞工作的热学模型问题.理想的火花塞应该能在点火的瞬间被立刻加热,并且在接下来的电脉冲过程中迅速冷却,由此在热量的存储与散发之间取得平衡,以避免自点火.本文力图展示一种具有自动调节源于点火区域热流能力的火花塞,其技术的关键是顶部绝缘体材料,它是由蓝宝石单晶制作,而非传统的氧化铝陶瓷.
There are offered many ways how to improve work of a spark plug.But one of the m ost important problems has not been solved yet.This is a thermal mode operation of a spark plug.The ideal spark plug should be instantly heated at the moment of occurrence of a spark and instantly cooled down in expectation of the foll owing electrical pulse.Thus it balances between preservation of heat for selfc leaning from scale and its removal in avoidance selfignition.In this article a uthor managed for this time to offer a spark plug with capability “selfregula tion” of heat flux removed from a zone of ignition.Essence of the offer is a t ip，which is transparent for heat flux.It is produced from single crystal of sap phire.
