关于汽车专业文件中引文对照★【Overview】car 汽车“汽车”（automobile）英文原意为“自动车”，在日本也称“自动车”（日本汉字中的汽车则是指我们所说的火车）其他文种也多是“自动车”，唯有我国例外。
"Vehicle" (automobile) English original intent was to "automatic car", in Japan, also known as "automatic car" (the Japanese characters in the car while we are talking about is the train) are also many other languages are "automatic car", only exception to our country.在我国，汽车是指有自身装备的动力装置驱动，一般具有四个或四个以上车轮，不依靠轨道或架线而在陆地行驶的车辆。
In China, the car is the power equipment has its own device drivers, usually have four or more wheels, not to rely on the track or land-line and in vehicles. 汽车通常被用作载运客、货和牵引客、货挂车，也有为完成特定运输任务或作业任务而将其改装或经装配了专用设备成为专用车辆，但不包括专供农业使用的机械。
Is often used as a vehicle to carry passengers, cargo and traction passenger and cargo trailers, but also for the completion of a specific mission or operation of transport and its mission, as modified or equipped with special equipment as a dedicated vehicle, but does not include special machinery for agricultural use. 全挂车和半挂车并无自带动力装置，他们与牵引汽车组成汽车列车时才属于汽车范畴。
简单介绍汽车英语作文初二Automobiles have become an integral part of our daily lives. They have revolutionized the way we travel, commute, and transport goods. From the early days of the horse-drawn carriage to the sleek and sophisticated vehicles of today, the evolution of the automobile industry has been a fascinating journey. In this essay, we will provide a simple introduction to the world of cars.At the heart of every automobile is the engine, the powerhouse that propels the vehicle forward. Engines come in various types, each with its own unique characteristics and advantages. The most common types of engines are the internal combustion engine, which uses a mixture of fuel and air to generate power, and the electric motor, which is powered by electricity. Within the internal combustion engine category, there are several subcategories, including gasoline engines, diesel engines, and hybrid engines that combine both gasoline and electric power.The body of a car is the outer shell that not only provides protection for the occupants but also contributes to the overall aesthetic appealof the vehicle. Car bodies can be made from a variety of materials, including steel, aluminum, and even composite materials like carbon fiber. The design of the body plays a crucial role in the car's aerodynamics, which affects fuel efficiency and performance.The suspension system is another important component of a car. This system is responsible for absorbing the impact of the road and ensuring a smooth and comfortable ride for the passengers. It typically consists of springs, shock absorbers, and other components that work together to maintain the car's stability and handling.The transmission system is responsible for transferring the power from the engine to the wheels. There are two main types of transmissions: manual and automatic. Manual transmissions require the driver to operate a clutch and shift gears manually, while automatic transmissions handle the gear shifting process automatically, providing a more convenient driving experience.Brakes are essential for the safety of the driver, passengers, and other road users. They are responsible for slowing down and stopping the car when needed. The most common types of brakes are disc brakes and drum brakes, each with its own advantages and disadvantages.Tires are the only part of the car that comes into direct contact withthe road. They play a crucial role in the vehicle's handling, traction, and overall performance. Tire size, tread pattern, and composition can all affect the car's performance and fuel efficiency.The interior of a car is where the driver and passengers spend most of their time. It includes features like the dashboard, seats, steering wheel, and various controls and displays. The design and layout of the interior can greatly impact the comfort and convenience of the driving experience.In recent years, the automotive industry has seen a surge in the development of advanced technologies and features. These include safety systems like airbags, anti-lock braking systems (ABS), and electronic stability control (ESC), as well as infotainment systems that integrate various multimedia and connectivity features.The environmental impact of automobiles has also become a significant concern. Automakers are now focusing on developing more fuel-efficient and eco-friendly vehicles, including hybrid and electric cars, to reduce greenhouse gas emissions and address the issue of climate change.The car-buying process is another important aspect of the automotive industry. Consumers have a wide range of choices when it comes to selecting a vehicle, from factors like price, fuel efficiency,and safety features to personal preferences and lifestyle needs.In conclusion, the world of automobiles is a complex and ever-evolving landscape. From the inner workings of the engine to the advanced technologies that are shaping the future of transportation, cars have become an integral part of our daily lives. Whether you're a car enthusiast or simply a daily commuter, understanding the basic components and features of a car can help you make informed decisions and appreciate the engineering marvels that have transformed the way we move.。

The power train has two maan functions :it conveys powerfrom the engine to the wheels , and it changes the amount of torque2. The power train consists of an engine , a transmission ,a clutch , a drive shaft and differential3. The feature of a manual transmission is to deliver enginepower to the front wheels and rear wheels4. manual transmissions usually have five speeds , which means that the output shaft can rotate faster than the input5. There are several basic components in the clutch , suchas the flywheel , clutch disk , pressure plate , release bearing and linkage.6 Automatic transmissions are used not only in many rear-wheel-dnve and four-whe el-dnve ve- lcles, but In most front-wheel-dnve ones1.T2.
