The performances indexes and curves of the model si 1126 diesel engine are obtained by simulation calculation ; the main curves for the affection of calibrate parameters on the performance of model si 1126 diesel engine are also obtained by simulation tests o the results and test data are analyzed o the major contents are as follows : a ) study on the demands of software and hardware environment of ktva on pc . kiva is originally designed for cray computer and workstation , but on pc it needs to be tested o b ) ktva code such as variables scopes of values and so on , needs revising to meet the needs of pc 應用該軟件,對縮短內燃機的設計周期、優化性能研究、環保和節能等方面都具有極高的應用價值。目前,國內同行業對kiva的運用尚處于起步階段,原因是國內所見到的kiva程序集不完整,且沒有漢化、沒有使用界面和使用說明書,軟件的運行環境要求特殊,而且復雜。本文作者通過對kiva的研究,揭示了該程序集的使用方法,恢復、完善并新增加了該程序集的功能;經過二次開發,建成了完整的內燃機仿真技術平臺。

G ) the convertion of si 1126 data into ktva input data file : ktva ' s values , definition , unit and format are tested many times . h ) the result of simulation computation is visualized and analyzed , i ) the study on sll 126 parameters ; by altering the ajustment data , their performance changes are studied 本文首次應用kiva仿真平臺,對s11126柴油機進行了仿真;通過主要參數(噴油量、轉速、噴嘴安裝高度等)的改變,分別計算出多項主要性能指標曲線和圖形,并對其進行分析,從而總結出以上參數的改變對性能的影響,驗證了kiva仿真平臺的強大功能。

By means of introduction digestion debug and absorption , the two softwares - ktvasv - lite and ktva - 3v run successfully on pc so that the definitions of variables scopes of values and the units and input format of the softwares are obtained , Kiva是內燃機燃燒過程計算機仿真程序集的總稱。該程序集由美國人于1985年開發,歷經了從kiva到kiva3v - erc的六次不斷完善的飛躍。

With the softwares autocad 2002 , tecplot 7 . 5 and fieldwiev , the calcuted result is visualized to draw animation , contour plot and average performance graphic chart Kiva軟件的計算,可以輸出動畫、等高線圖、曲線圖、數據文件形式的可視性結果。

In order to use kiva - 3v in windows system and personal computer , some parameters and subroutines was adapted to the environment 本文給出了內燃機燃燒模擬的主要的數學模型,并詳細探討了各方程的數值求解方法。

Kiva - 3 v was written for giant computer , using the cray fortran ( cft ) and cft77 compilers 編制了與專業圖形處理軟件接口程序,實現了二維和三維圖形的輸出。
