Abstract : 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 self ? c leaning from scale and its removal in avoidance self ? ignition. in this article a uthor managed for this time to offer a spark plug with capability “ self ? regula 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
