汽车文化项目作业 题 目：启动机的工作原理与检测 姓 名：张洪金 班 级：检修3111 学 号：15 二〇一二年 十一月 二十六日 摘要：本文以汽车启动机为中心，将此文共分为五大部分。首先概括性地描述了汽车启动系统的组成、工作过程以及原理，紧接着启动机作为汽车启动系统的重要组成部分，详细且全面地介绍启动机的结构组成、所起作用、主要类型以及常见几种启动机的原理图，并以原理图为契机，深刻地叙述了汽车启动机的工作过程与原理。除此之外，随着汽车保有量的逐年攀升，汽车售后服务质量特别是维修技术还有待进一步加强，否则汽车服务市场难以满足消费者需求，因此此论文还从汽车维修的角度出发，详实地描述了启动机主要部件维护与检修的方法，启动机常见故障的检测步骤和排除方法，最后对于汽车在现实使用中启动机所出现的启动机典型故障案例以及不良反应进行详细分析并介绍诊断与排除方法！ 关键词：启动系统； 启动机； 原理； 维护与检修； 案例； Abstract Since 1990s, Chinas economy is in rapid developing, as identity and status symbol automobile have started mass into the household. After 1999, car 4S shops throughout China have mushroomed all. Auto 4S inn competition is also more and more intense. In order to be in the competition for the survival and development of automobile 4S inn marketing strategy research appears especially important, through the investigation of 4S inn analysis shows that, in addition to enhance after-sales service 4S inn outside, form to increase profit scale and stable customer groups also became currently 4S inn of sustainable development of main ways. In a short period of ascension sales and service personnels quality, make it become high-quality professional managers and professional staff, and constantly perfect service system, and constantly introduce new favourable activity, and proposes the corresponding product strategy, price strategy, distribution strategy, promotion strategy, network marketing development strategy, auto after-sales service strategies and competitive strategy is car 4Sinn primary good work.
