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

    文摘:在如何提高火花塞的工作質量方面有多種方法，但是其中最重要的一個問題還沒有得到解決，那就是火花塞工作的熱學模型問題.理想的火花塞應該能在點火的瞬間被立刻加熱，並且在接下來的電脈沖過程中迅速冷卻，由此在熱量的存儲與散發之間取得平衡，以避免自點火.本文力圖展示一種具有自動調節源於點火區域熱流能力的火花塞，其技術的關鍵是頂部絕緣體材料，它是由藍寶石單晶製作，而非傳統的氧化鋁陶瓷

    當流量及壓差降低至一定程度時，共振腔還可能削弱換熱；加熱功率的提高會增加流體（水）的溫度，流體的粘度會隨著降低，這會減少對流體脈動的阻礙，使脈動衰減得更慢，而脈動幅度的增加會增強換熱，故加熱功率對有脈動的對流換熱是有影響的；自振腔產生的流體脈動頻率是自振腔固有頻率或其整數倍，流體脈動頻率過高或過低都不利於對流換熱，存在一有利於強化換熱的頻率范圍。
