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The technology of alternating - current - boosting by way of constant current is successfully used to charge capacitors with 25 kilojoules of energy in only eight seconds. rail - gap switch with performances of long life and highly steady state are designed. and the high voltage pulse generator, which can produce low - excursion and fast - rise pulses, are designed by using double trigger circuit and hydro - thyristor as switch
