大学生方程式赛车设计 （发动机匹配试算与装配设计）
摘 要
中国大学生方程式汽车大赛是由各个大学在校学生组队参加的汽车设计与制造的一项比赛。各参赛车队严格遵循比赛规则，在一年内自主设计和生产出一辆在各方面优秀的小型单人座休闲赛车，进行比赛。
本文是对大学生方程式赛车发动机系统的匹配试算和结构设计，通过了解发动机的性能参数、结构参数，运用汽车设计、发动机原理、汽车构造等知识，通过网上查询资料对发动机进行选择。文章主要论述如何改进发动机的进排气及冷却系统，使发动机达到预想的状态，且符合大赛的规定。我将采用GT-Power、FLUNT等软件对排气系统进行优化设计，采用四个分置的进气歧管，避免了由于进排气时间不同而出现挣气现象，使得进排气更加顺畅，发动机在动力方面更出色。建议进气系统使用限流阀这样可以使赛车更加安全，这样可以让学生更好的学习如何改进进气系统，做成两头锥的形状，使得进气无死角，又符合大赛规定。应用流体力学设计谐振腔，使得进气量多。

Design of FSAE
(trial matching and assembly design of engine)
ABSTRACT
Contest of Chinese college students formula car is by each team for university students in car design and manufacture of a game. 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
