There will always be that when you own something when you do not think it would be valuable, but also do not see the value of it, but when you lose it when it come to repentance, but that at the moment when the lateness of the hour, too late for regrets and. I now have such a similar feel. A week-long automotive engine disassembly internship is over, memories of this time, he reluctantly are true. Wanted to be back in a week ago, then put in every day practice as seven hours to 27 hours use. This is true, this internship opportunities for me are too precious a true. In this internship, I learned about auto engines knowledge, are ever at a lesson on what can not be compared. And I once again felt the profound theoretical and practical combination of the need. Teacher because of the arrangement to the engine of our components are Santana 2000 engine. First of all, for the automotive engine theory of knowledge, I understand that: Santana in Germany Volkswagen Ltd. 1982 products. The company entered Shanghai in 1983, to cooperate with the development of our country has been the development of three generations - four generations of production lines, and in 95 years will be Santana 2000 Electronic Fuel injection system into the market. The main parameters of motor vehicles including technical parameters, the basic parameters, engine and chassis parameters parameters. Structure for the JV type engine, the combustion chamber for the ball flat, so that the function of strong squeezing gas area, to reduce fuel consumption and air pollution Valve for overhead camshaft type, camshaft push rod directly. Advantages of simple structure, the inertia of small parts, the system stiffness, and improve the effective engine speed. Valve for the hydraulic rod to mention, the automatic adjustment of valve clearance. Intake system has electric heaters and temperature control the intake valve, you can ensure that a smooth start and shorten the warm-up time. Closed water cooling system uses forced circulation. The basic structure of the modern automobile engine from crank linkage, valve body, transmission system, lubrication system, cooling system, ignition system, start the Department of the composition. Linkage crank engines are energy conversion and transmission of power institutions. Valve bodies are engines of ventilators, ventilation process: on time and turn off the control valve to ensure full combustion gas mixed with gas and emissions. Supply lines are guaranteed to give a total cylinder fresh combustible mixture and export emissions, and in accordance with the different engine operating conditions the supply of different quantity and concentration of combustible gas mixture. 中文翻译如下：人们总说，当你拥有一样东西的时候，你会不觉得的它的珍贵，也看不到它的价值所在，但是当你失去它的时候才恍然悔悟，此刻却以为时已晚，后悔莫及。我现在就有这么一种类似的感受。 为期一周的汽车发动机拆装实习结束了，回忆这段时光，竟真的是恋恋不舍。恨不得能回到一周前，然后把每天实习的7个小时当成27个小时来用。确实如此，这次实习的机会对我来说真的是太珍贵了。 在这次实习中，我学习到的关于汽车发动机的知识，是在以往任何一节课上都不能所比拟的。而我也再一次深刻感受到了理论和实践结合的必要性。 由于老师的安排，我们组分到的发动机是桑塔纳2000型发动机。首先，对于汽车发动机理论知识的学习，我了解到： 桑塔纳轿车是德国大众汽车有限公司1982年的产品。该公司于1983年进入上海，同我国进行合作开发，目前已发展为三代-四代生产线，并于95年将桑塔纳2000电控汽油喷射系统投入市场。 汽车的主要参数包括技术参数、基本参数、发动机参数和底盘 参数。 发动机结构为JV型，燃烧室为扁球形，这样可以则功能强挤气面积，减低油耗和大气污染配气机构凸轮轴为顶置式，凸轮轴直接推动连杆。优点为结构简单、零件惯性小、系统刚度大、有效提高发动机转速。气门提杆为液压式，气门间隙自动调节。进气系统有电加热器和温度控制进气阀，可以确保汽车顺利启动和缩短暖机时间。冷却系统采用闭式水冷强制循环。 现代汽车发动机基本结构由曲柄连杆机构、配气机构、传动系、润滑系、冷却系、点火系、启动系组成。曲柄连杆机构是发动机进行能量转换和传递动力的机构。配气机构是发动机的换气机构，换气过程：控制气门按时关闭，保证气配时充分燃烧混合气和排放废气。供给系是保证向气缸共给新鲜可燃混合气和导出废气，并按照发动机不同工况供给不同数量和浓度的可燃混合气。 这篇挺好的啊，嘻嘻
