The fuel tank is used to store the fuel of engine needed. It is usually located in rear of the vehicle. The fuel tank is designed to fit around frame and to be protected from impacts. These are several baffles insides the fuel tank to restrict fuel movement during rapid starts and stops, cornering, and so on. The fuel cap on the fuel tank is used to keep the fuel from splashing out, release the vacuum created by the fuel removing, and prevent vapors from escaping directly into the atmosphere. 3.The fuel levels are measured by a fuel-metering unit. One style of the unit has a hinged float inside the tank. As the float position changes with different levels of fuel, the needle position on the dashboard gauge changes. 4.作业及小结 翻译: The fuel system is critical to operation. The system consists of the fuel tank, lines, pump, filter, carburetor, and injectors 第14讲Unit10 typical EFI System 课前分析: 1.教学内容及时间分配 Engine operation 1学时 Notes 1学时 2.教学目的 通过对文章的翻译、学习、和讲解，掌握第十单元的汽车电子控制燃油喷射系统系统相关的英文知识，能够牢记该单元的汽车相关英语单词，并且能够拥有翻译Fuel Pump等部分文章的英语基础和理解能力。 3.教学重难点 重点:Engine operation 4.教学方法 本教学环节采用理论教学方法。通过举例、多媒体演示面，学生可以更直观的学习。 5.板书布置 详见教学内容 教学内容: 0.导入 通过对以往学习的汽车专业英语知识的回顾，并对学生英语单词进行检查，通过对上次课程回顾，引入本次课程。 1.In the bellows-type electrical fuel pump, a metal bellows is used instead of a diaphragm. It operates from the movement of the armature in the magnetic coil. The bellows is stretched and squeezed to cause the vacuum and pressure. 2. The roller vane electrical fuel pumps are used on newer vehicles. As the electric motor turns an impeller, fuel is drawn in at the inlet port of the pump. It is pressurized and sent out the discharge port for delivery to the engine. The impeller at the inlet end serves as a vapor separator. A pressure relief valve keeps fuel pump pressure at a constant level. 3. Fuel systems that have electrical fuel pumps and fuel injectors may use a fuel pressure regulator to keep the fuel pressure constant. 4.Notes The gasoline engines may have one or two filters in the fuel system. The first filter is usually placed inside the fuel tank to prevent large pieces of contaminant from damaging the fuel pump. The second one is an in-line type or an in-carburetor type used to filter out small dirt particles. 5.作业及小结: 翻译: The flow of air and fuel through the carburetor is controlled with a throttle plate. The throttle plate is placed below the venturi and connected to the acceleration pedal. As the driver's foot on the pedal is depressed, the throttle plate opens, and there is very little restriction of air and fuel. The load and speed is increased. 第15讲 Unit11 Suspension 课前分析: 1.教学内容及时间分配 New words and phrases 1学时 Springs and dampers 1学时 2.教学目的 通过对文章的翻译、学习、和讲解，掌握第十单元的汽车电控燃油喷射系统的英文知识，能够牢记该单元的汽车相关英语单词，并且能够拥有翻译Fuel injection部分文章的英语基础和理解能力。 3.教学重难点 重点:Springs and dampers 4.教学方法 本教学环节采用理论教学方法。通过举例、多媒体演示面，学生可以更直观的学习。 5.板书布置 详见教学内容 教学内容: 0.导入 通过结合日常生活中的实例以及发动机的整个构造，引出汽车悬架系统的作用和用途，从而引入正文，介绍汽车燃油供给系统相关知识。 1.New words and phrases 万向节 universal joint, U-joint 十字轴式万向节Cardan type U-joint 叉子 yoke, fork 十字轴 spider, center cross 滚针轴承 needle bearing 滑脂嘴(油嘴)lubricating fitting, nipple 等角速 constant angular velocity 双联式万向节 dual Cardan type U-joint 球叉式万向节 Weiss type U-joint 球笼式万向节 Rzeppa type U-joint 星形套 inner race housing 球形壳 outer race shell 保持架，球笼 retainer, ball cage 挠性万向节 flexible U-joint 无缝钢管 seamless steel tube 主减速器 final drive 主动(小)齿轮 drive pinion 伞齿轮 bevel gear 双曲面齿轮 hypoid gear 单级减速 single reduction 2. Automobile suspension system has two basic functions, to keep car's wheels in firm contact with the road and to provide comfortable ride form the passengers. A lot of the system's work is done by the spring. Under normal conditions, the springs support the body of the car evenly by compressing and rebounding with every up-and-down movement. This up-and-down movement, however, causes bouncing and swaying after each bump and is very uncomfortable to the passenger. This uncomfortable effects are reduced by the shock absorbers. 3. 作业及小结 Suspension, when discussing cars, refers to the use of the front and rear springs to suspend a vehicle's "sprung" weight. The springs used on today's cars and trucks are constructed in a variety of types, sizes. Types include leaf springs, coil springs, air springs, and torsion bars. They may be paired off on vehicles in various combinations and are attached to vehicles by several different mounting techniques. 第16讲 Unit11 Suspension System 课前分析: 1.教学内容及时间分配 Passive suspensions 1学时 Notes 1学时 2.教学目的 通过对文章的翻译、学习、和讲解，掌握第十一单元的汽车悬架系统相关的英文知识，能够牢记该单元的汽车相关英语单词，并且能够拥有翻译Passive suspensions等部分文章的英语基础和理解能力。 3.教学重难点 重点:Passive suspensions 4.教学方法 本教学环节采用理论教学方法。通过举例、多媒体演示面，学生可以更直观的学习。 5.板书布置 详见教学内容 教学内容: 0.导入 通过对以往学习的汽车专业英语知识的回顾，并对学生英语单词进行检查，通过对上次课程回顾，引入本次课程。 1. Passive suspensions The leaf springs most commonly used in automobiles is made up of several long plates, or leaves. The leaf spring acts like a flexible. For example, if you tried to bend a solid beam, the top edge would try to get longer while the bottom edge would try to push together. The result is that the top edge of the beam might pull apart and the beam might break. 2. suspension types In the past, a wide variety of direct and indirect shock absorbing devices were used to control spring action of passenger cars. Today, direct, double-acting hydraulic shock absorbers and shock absorber struts have almost universal application. 3. Because the leaf spring consists of a series of thin leaves, one on top of another, it does not break when bent. When the spring is bent, the individual leaves bend and slip over one another. This provides a spring with great flexibility and strength. 4.Notes In the rear-suspension systems of many cars, coil springs are used instead of leaf springs. The coil spring is made from a length of steel road rod would into a coil. The coil spring is very elastic and will compress when a weight is put on it. The heavier the weight the more spring will compress. 5.作业及小结: 翻译: A rear-suspension system uses coil springs. Each spring is assembled between spring seats in the car frame or body and lower control arms, or pads, on the axle housing. When the rear wheels hit a hole or a bump in the road, the springs expand or compress to absorb the shock.
