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 plate - tube evaporator, the single back - fin evaporator and the box condenser. after analyzing the physical model and setting up the mathematical model according to the two - phase flow of adiabatic capillary tubes, it also numerically simulates and analyzes the different effects of main parameters on the capillary tube length. based on the heat transfer analysis and counting of thermal insulation layer, the cad system accomplishes the parametric design and drawings of the refrigerator body
