  1. Abstract : in the research of internal combustion engine, recordingin - cylinder pressure and temperature is an essential technique to study the thermal cycle of internal combustion engine. the combustion analyzer developed in this study will give both the measurements at sampling points per crank angle or sampling cycle, calculate and show the real time parameters which decide the working process of internal combustion engine, such as pressure accelerating rate, indicateed mean effective pressure, cycle - to - cycle variation, heat release rate, etc. compared with the imported congeneric products, the analyzer has many advantages such as chinese interface, low price, easy operateing, convenience in maintainance and easy upgrading

    文摘:為了測錄內機缸內的壓力及溫度,開發了一種內分析儀.該分析儀由國產高據採集卡及自行開發的控制軟體組成.它不僅能精確設置每度曲軸轉角內采樣點的個和採集循環,而且在採集過程中能實時計算和表徵內機工作過程的壓力升高、平均示壓力、循環變動、放熱等參.經實際使用以及與國外產品相比表明,此分析儀具有全中文界面、價格低、操作簡單、使用維護方便、功能便於擴充等優點
  2. Burn - rate exponent

  3. In order to study the regeneration mechanism of dpf in detail, we still need a mathematical model of the channel unit, which present temperature field and the soot reaction rate of the channel. finally, it points out the influences of various factors to the regeneration process by computing the numerical solution of model under different boundary conditions and geometry parameters, such as the initial temperature, the gas flow rate, the oxygen concentration, the sediment quantity and the wall thickness of the filters, and so on. in this way, the paper provides theoretical guidance for optimization design of the dpf

    首先研究了干凈壁流式過濾體的加熱特性,然後在加熱和理論的基礎上建立了微粒捕集器再生過程的學模型,並對模型進行了值計算,得到了捕集器內部的三維溫度場分佈以及溫度梯度分佈,結果與實驗值吻合較好,驗證了模型的正確性;為了詳細的研究微粒捕集器的再生機理,建立了孔道單元學模型,得到了孔道內的溫度場分佈和微粒反應分佈;最後,通過求解模型在不同邊界條件和不同幾何參下的值解,分析了各種因素對再生過程的影響,如過濾體初始溫度、過濾體內氣流的流動、氧濃度、微粒沉積量以及過濾體壁面厚度,為微粒捕集器的優化設計提供理論導。
