蓝宝石火花塞(英文)

Spark Plug "Sapphire

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 most 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 following electrical pulse.Thus it balances between preservation of heat for self-cleaning from scale and its removal in avoidance self-ignition.In this article author managed for this time to offer a spark plug with capability 'self-regulation' of heat flux removed from a zone of ignition.Essence of the offer is a tip,which is transparent for heat flux.It is produced from single crystal of sapphire.
