文档介绍：ZHEJIANG WATER CONSERVANCY AND HYDROPOWER COLLEGE 毕业设计(论文) 题目: 宝马 523Li 轿车空调系统常见故障检修系(部): 机械电子工程系专业班级: 汽车 08 -2 姓名: 方伟学号: 200832081 指导教师: 陈庆平 2011 年5月 24日浙江水利水电专科学校毕业论文 1 摘要本人通过在毕业实践单位的实****和自己其他渠道的知识,对宝马 F18 系列 523Li 轿车的空调系统有了一定的了解。宝马 F18 车系是宝马集团针对中国市场打造的新一代 5 系轿车,它包括 520Li 、523Li 、528Li 、535Li 这四种车型。宝马F18 车系是由华晨宝马沈阳工厂在 2009 年开始制造的, 可以说它是宝马唯一一款的国产车。523Li 轿车采用的空调是自动恒温空调,简称(IHKA )。自动恒温空调可以改善驾驶人员所在的环境,这不仅能增加驾驶的乐趣,还能提高驾驶的安全系数。随着生活水平的提高,人们对汽车环境舒适性的要求越来越高, 汽车空调能够调节车室内的温度、湿度、风速、清洁度和噪音,一定程度上满足了人们对于舒适性的要求。不过,由于空调系统对工作所在的环境有一定的要求, 一旦出现故障,可能会导致空调无法正常工作,影响汽车的舒适性,要排除故障, 必须对空调系统的构成和工作原理有全面的理解。本文结合了工作实践和所学理论知识,对宝马 F18 车系 523Li 车型空调系统所引起的故障作了简单分析,并总结了故障的基本排除方法。关键词宝马 523Li ;空调系统;故障;排除 Abstract Igraduated from practice bypractice units from other sources and their own knowledge, F18 Series 523Li BMW car air-conditioning systems have acertain understanding. BMW F18 BMW Group cars are built for the Chinese market anew generation of5Series sedans, which includes the 520Li, 523Li, 528Li, 535Li these four models. F18 BMW cars from BMW Brilliance Shenyang factory started manufacturing in2009, and can say that itisthe only one home-made BMW vehicles. 523Li sedan with air conditioning isautomatic climate control, referred toas(IHKA). Automatic climate control air conditioning can improve the environment inwhich the driver, not only can increase the driving pleasure, but also 浙江水利水电专科学校毕业论文 2 improve driving safety factor.
