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 -
