西安航空职业技术学院 毕业设计论文 PAGE 1 PAGE 1 汽车发动机冷却系统分析 【摘要】 汽车在现代社会生活中起着不可缺少的作用，越来越多的汽车进入了普通家庭，每个人的汽车梦不再是梦。要使汽车能更好的为我们服务，就得从技术、质量等方面来改变汽车的质量,从而把汽车全面打造成人类必不可少生活工具。作为汽车专业的学生，对汽车的基本结构和工作原理要有所认识和了解，尤其是汽车发动机,在现代汽车发动机中,冷却系统起着给发动机进行冷却的作用,从而保证发动机的正常运行,不仅如此,有些先进的汽车发动机上的冷却系统是要求冷却的作用要达到精确冷却、智能化冷却等作用及功能。这些都是冷却系统比较新鲜的技术，更应该对其深入了解，才能掌握对汽车简单故障的诊断和排除方法。本文从介绍发动机冷却系的研究目的和意义、作用和结构组成、到对冷却系统的故障再到冷却系统新技术的展望等进行分析介绍，并进行具体讲解，使汽车人员对汽车发动机冷却系有更深的了解，从而能对汽车发动机冷却系合理地使用、出现故障时能够得心应手的进行诊断和排除。 关键词： 汽车发动机 冷却系统分析 诊断和排除 Abstract: Car in modern society life plays an indispensable role, more and more vehicles into the ordinary families, each person's car is no longer a dream dreams. To make the car to better serve us, from technology, quality and so on to change the quality of the car, so as to give the car to fight a comprehensive human essential tool life. As a motor major, for car the basic structure and working principle of to know and understand, especially the car engine, in the modern automobile engine, cooling system plays to engine for cooling, so as to ensure the normal operation of the engine, not only that, some advanced automobile engine cooling system is to require the cooling to achieve precise cooling, cooling effect such as intelligent and function. These are cooling system is fresh technology, and more thorough understanding of its should, to master car simple of fault diagnosis and elimination method. This paper introduces the engine cooling of the department of research purpose and meaning, function and structure, to the cooling system fault to cooling system of the new technology outlook analysis is introduced, and explained, to make the car personnel of automobile engine cooling is a deeper understanding of, and that can of automobile engine cooling is reasonable to use, failure can handy for diagnosis and ruled out.
