郑州交通职业学院 毕 业 论 文 论文题目：浅析汽车发动机的维护与保养 所属系别 车辆工程系 专业班级 汽车检测与维修技术5班 姓 名 学 号 指导教师 撰写日期 年 月 摘 要 发动机是汽车的心脏，保养的好与坏直接影响着汽车的性能和它的使用寿命。平常检查与保养应慎之又慎，外部可用引擎清洗剂清洗干净，至于内部则会在工作中产生积碳、杂质、胶质等废物，汽车发动机的冷却系统是保持发动机正常工作的重要部件，如果发动机冷却系统的维修率很高，就会引起发动机其他部件的损坏，使发动机的整体工作能力受到影响，因此，汽车发动机冷却系统的维护与保养就显得尤为重要，那么，怎样才能使汽车发动机的冷却系统保持良好的状态呢？日常维护保养的内容包括：清洁、紧固、润滑。保持车辆的干净、整洁、防止水和灰尘腐蚀车身及零件。在车辆行驶一定的里程后，要对车辆各部件连接处的螺栓进行检查、调整；发现有松动的地方要按要求及时拧紧，防止事故隐患，保证行车安全。润滑包括发动机润滑、变速器润滑、差速器润滑、轮毂润滑等，是保证车辆各运动部件正常运转、减小运转阻力，降低温度、减少磨损的重要手段。汽车的修理和维护是大家头痛的问题。如果平时不知好好保养爱车，或者驾车习惯不好，一旦车子得进厂大修特修，不单得付出一笔可观的费用，时间的浪费和精神上的折磨，更是难以数计。所以，汽车要时时注意保养，从你拥有汽车的第一天就小心维护，以免因小失大呢？本文从汽车理论知识出发，为您讲解汽车发动机的维修和保养的基础知识。 关键词：发动机，维护，检修，保养 Abstract The engine is the heart of the car, the maintenance of good and bad, directly affect the cars performance and its service life. Usual checks and maintenance should be cautious, externally available engine cleaner clean, As for the internal work will produce carbon deposits, impurities, glial waste, automotive engine cooling system is an important part to keep the engine working properly, if high repair rate of the engine cooling system, it will cause damage to other parts of the engine, the engines overall ability to work is affected, therefore, the care and maintenance of automotive engine cooling system is particularly important, then, how to make a car engine cooling system to keep in good condition? Day-to-day maintenance of content including: cleaning, tightening, lubrication. Keep your car clean and tidy to prevent water and dust corrosion body and parts. Certain mileage vehicles, vehicle components connected at bolt check, adjustment; loose place in accordance with the requirements of tightened in a timely manner to prevent potential accidents and ensure traffic safety. Lubrication engine lubrication, lubrication of transmissions, differentials lubrication, hub lubrication, is to ensure the normal operation of the vehicle moving parts to reduce the running resistance, lower tem
