| In recent years, computer simulation has become a powerful tool to analyze turbocharged diesel engine. There are many commercial soft-wares appearing which give the user great convenience. While being no source codes, they brought a lot of inconvenience to scientific research. In order to research the performance of diesel engine in-depth, it is necessary to develop the source programming with independent intellectual property rights.In this paper, the source programming of the working process of the diesel engine is perfected basing on MK14. Programs can calculate the working process of diesel engine or gasoline engine, four-stroke or two-stroke, pressurized or non-pressurized. And it calculates the working process of the diesel engine with adopting one-dimensional unsteady flow. This program uses one-dimensional flow model to simulate the intake and exhaust pipes of gas flow and characteristic line method to solve.In Microsoft Visual Basic 6.0 development environment, using VB language to compile Visual programming which is man-machine interface of the working process with adopting one-dimensional unsteady numerical calculation. Using mixing programming technology Fortran and VB to realize the VB to call Fortran programs. Finishing data input and output functions in VB designing interface. The calculated results are displaying in terms of data list and graphic which can also be derived to Excel in further treatment.In order to verify the accuracy of the programming, in this paper, TBD234V12 diesel engine working process of numerical calculation. The numerical results compared with the testing which verifies the correctness of the programming. In order to carry on data comparison variously, TBD234V12 diesel engine calculation model was established with commercial software GT-Power, which adopting the same basic raw data to be calculated. The numerical data which cannot be measured compared with the calculated data in the programming and they are consistent with each other. |
