Abstract：A diesel engine is a complicated energy conversion device. The digital design technology for diesel engines include the computer-aided design, simulation, visualization and many others. Through VB interface and the drawing program inside AutoCAD and Matlab/Simulink software, the integration of cylinder working process calculation & analysis and the CAD drawing of the cylinder body can be achieved. Reading data and results that are in stored in the database technology store, we optimized structure parameters and did analysis more efficiently.
