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:為了測錄內燃機缸內的壓力及溫度，開發了一種內燃機燃燒分析儀.該分析儀由國產高速數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數和採集循環數，而且在採集過程中能實時計算和表徵內燃機工作過程的壓力升高率、平均指示壓力、循環變動率、放熱率等參數.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 -
At the conditions with the same fuel injection quantity per cycle and the same engine speed, with the increase of the additive mass fraction in the fuel, the ignition and heat release timings brought forward, the peak of heat release rate increased and the operating range at low engine load was enlarged obviously. however, excessive additives will make the engine be prone to knock, run rudely and shorten the operating range at high engine load
在相同循環噴油量和相同轉速的條件下，隨著添加劑質量分數的增加， hcci著火和燃燒放熱提前，燃燒放熱峰值提高，低負荷工況范圍明顯拓寬，但過高的添加劑質量分數會使得發動機爆震，工作粗暴，導致高負荷工況變窄。 -
The coefficients of these concepts can be given as equivalent heat drop and rate of bleeding. as a quantitative analysis method of auxiliary system, it is so convenient that multi - cycle theory can be further perfected
上述概念可以象抽汽等效熱降和抽汽效率一樣作為一次性參數給出，作為輔助系統熱經濟性的定量分析方法十分方便，從而以此完善了多重循環的分析方法。 -
Based on analysis of multi - cycle theory ， this thesis offers the concepts of generalized releasing coefficients of steam bleeding and influencing rate on steam releasing and provides their basic principle for application and heat economic index of quantitative analysis
本文在對供熱機組多重循環理論進行分析的基礎上，提出了「廣義抽汽排汽系數」和「抽汽影響率」的概念，並給出了其應用基本法則和定量分析的熱經濟指標。
