Abstract
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 600cc, 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.
In this paper, we propose the design method of engine intake and exhaust system for a Formula SAE competition vehicle using some numerical simulation methods
