Each participating team strictly follow the rules of the game, the independent design and production in one year out of a good in all aspects of small single leisure car, for the game. This article is on college students formula engine system matching of the trial and the structure design, through understanding engine performance parameters, structure parameters, using the principle of automobile design, engine, automobile structure, such as knowledge, through the Internet query information of engine to choose. This paper mainly discusses how to improve the inlet and exhaust and cooling system of engine, the engine the desired state, and in accordance with the rules of the competition. I will use the GT - Power, FLUNT optimize the exhaust system design of software, such as the four division of the intake manifold, to avoid the phenomenon make gas due to different inlet and exhaust time, makes the exhaust more smoothly and the engine better in terms of Power. Suggested that the air intake system use flow-limiting valve so that we can make cars safer, this can let students learn how to better improve the air intake system, make it two of the shape of the nose cone, making intake no dead Angle, and comply with the regulations of competition. Application of fluid mechanics cavity is designed to ensure the air inflow. Keywords: formula (FSAE), engine, match, into the exhaust 目 录 第一章 大学生方程式赛车简介 1 §1.1 1 §1.2 愿景与使命 1 第二章 发动机的匹配 1 §2.1.1 匹配的定义 1 §2.1.2 发动机匹配的应用场合 2 §2.2
