The regulations of Formula SAE® competitions restrain design, tuning, and improvement on engine in order to keep safety on driving. The competitors have basically chosen a 600 cc, 4-stroke engine for motorcycle according to the regulations. Therefore, it is necessary for higher engine performance to improve combustion by investigation of air intake and exhaust component design while the regulation agreement is the most important factor. Recently, many competitors have been using a high performance Engine Control Unit (ECU) easy to suitably control the engine combustion. The competitors can focus on optimization of the intake and exhaust components using ECU. Best tuning of each component is very difficult work because the design factors of these components have complicated relations with engine performance. Here, our interest is a method to reduce the optimization time of the system.

The core education of the Faculty of Engineering at Kokushikan University is creative engineering education by manufacturing generally on the base of the result of development research. Some of the students of the Department of Mechanical Engineering and Applied Information Technology participate in the formula car program. They conceive, design, fabricate by themselves, and compete with small formula-style racing cars at the Formula SAE® (the Society of Automotive Engineers) Competition held annually in USA under the auspices of SAE. This program is planned in order to bring up the ability of settling and solving the problems through teamwork. In addition to the PBL education system, the authors refer to the result of the development research connected with this practical education in this paper.
