Kiva Is Research And Computer Simulation Of The Sl1126 Diesel Engine Combustion Process

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,. 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. 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 ob) KTVA code such as variables scopes of values and so on, needs revising to meet the needs of PC.c) KTVA code which must be amended because of lacking several visualization subroutine needs revising and supplementing to compile executive file.d) KTVA computing results have been visualized in the code , there is no vesualization software but visual files; therefore it's necessary to study the visual software so as to turn the KTVA visual files into view.e) The substitute for the filoutf subroutine meets the needs of the advanced animation postscript.f) The simulation computation of si 1126 diesel engine; double connecting rod engine equaling to KTVA single connecting rod model, mesh model and preparation of model data for running.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.
