    Abstract: A engine working process is simulated using GT-POWER. Some optimization on the engine intake system is performed and the main parameters of the intake manifold structure are obtained. According to the data, design model is developed by using 3D software Pro/E. The model is transformed to rapid prototyping center with STL form, where a rapid prototype model is made and tested on the engine test bench to examine design index. During the development process, advantage tools in the modern automotive industry are applied in calculating, designing and manufacturing, and much high quality and efficient job are achieved.
