汽车技术(英语版)(高等学校应用型特色规划教材·汽车工程系列) ![]()
本书全面细致地介绍了汽车构造、汽车工作原理、汽车检测维修以及汽车新技术的相关知识。全书共分为23个单元,涵盖发动机和底盘几乎所有总成。其中发动机部分在传统基本构造基础上增加新的内容,如进气增压技术、柴油发动机共轨技术和混合动力汽车技术;底盘部分对自动变速器、无极变速器和制动防抱死系统(驱动防滑转系统)的结构及工作原理进行了细致的阐述。每个单元包括正文、词汇、例句解析和思考题四部分。
本书既可作为大学本科、专科院校汽车类专业的专业英语教材或汽车构造双语教学教材,也可作为专业技术人员对外技术交流的参考书。
近20年来,我国汽车工业迅猛发展,已成为国家的支柱产业。轿车逐步进入家庭,成为人们日常工作和生活中不可缺少的工具。货车在经济领域发挥的作用也愈加突出。
中国汽车行业中,企业的跨国发展已迅速展开,国际交流与合作日益增多,这种交流与合作迫切需要工作人员掌握扎实的专业技术英语。 本书以全英文的体例讲述了汽车的构造和工作原理。编者在国外教学的两年期间,结合了国外汽车专业教材和英语教学的特点,参考了大量的英文教学和参考书籍编写了此书。 本书共分23个单元,其中1~11单元介绍发动机的基本概念,工作原理和构造;12~23单元介绍底盘各总成结构和工作原理,其最大特点是:内容全面细致,每部分内容结构完整连续,语言使用规范准确,是纯正的英文书籍。在具体内容方面,既有传统的汽车结构、工作原理和检测维修,又有较先进且成熟使用的汽车技术,如电控燃油喷射发动机、混合动力、自动变速器和制动防抱死控制系统等。目前各高校正积极准备或已在推行双语教学,但在外文教材方面受到很大限制,本书适时地解决了这一难题,是理想的高等院校双语教学教材。对汽车专业不同专业方向的学生而言也是理想的专业英语教材。此外,本书也是汽车行业专业技术人员理想的英文参考书籍,对热切期望提高专业技术英语水平的读者会有帮助。 本书由李清民担任主编,刁立福、王林超、吴芷红、刘志信担任副主编。 由于时间仓促,编者水平有限,书中难免有不妥之处甚至错误,敬请读者谅解并批评指正。 编 者
