背景知识内燃机与外燃机的最大不同在于它的燃料在其内部燃烧。内燃机的种类十分繁多，我们常见的汽油机、柴油机是典型的内燃机。我们不常见的火箭发动机和飞机上装配的喷气式发动机也属于内燃机。不过，由于动力输出方式不同，前两者和后两者又存在着巨大的差异。一般地，在地面上使用的多是前者，在空中使用的多是后者。当然有些汽车制造者出于创造世界汽车车速新纪录的目的，也在汽车上装用过喷气式发动机，但这总是很特殊的例子，并不存在批量生产的适用性。

2. Brief Introduction of Automobile Marketing
Automobile marketing is the best choice among the numerous manufacturers, multiple brands and automobile models flooding the market. Seller’s market has been totally evolved into the buyer’s market, and the automobile industry has accelerated the process of survival of the fittest. However, to fast and effectively promote the business performance of the enterprise depends on the scientificity and rationality of the marketing strategy as well as the executive capability of the marketing talents and marketing team of the enterprise. The notion of enterprise marketing undergoes the transition from “productionoriented” to “customer-oriented”, as well as “basing sales on production” to “basing production on sales”; hence, the motto of modern enterprises is that “customers are the God”.

控制器局域网CAN总线技术
现代汽车中所使用的电子控制系统和通讯系统越来越多，如发动机电控系统、自动变速器控制系统、防抱死制动系统(ABS)、自动巡航系统(ACC)和车载多媒体系统等，这些系统之间。系统和汽车的显示仪表之间，系统和汽车故障诊断系统之间均需要进行数据交换，如此巨大的数据交换量，如仍然采用传统数据交换的方法，即用导线进行点对点的连接的传输方式将是难以想象的，据统计，如采用普通线索，一个中级轿车就需要线索插头300 个左右，插针总数将达到2000个左右，线索总长超过1. 6Km，不但装配复杂而且故障率会很高。因此，用串行数据传输系统取而代之就成为必然的选择
TCS 牵引力控制系统
TCS是英文Traction Control System 三个字的简写，中文为「循迹控制系统」就是防止轮胎打滑空转控制系统。即牵引力控制系统。汽车在光滑路面制动时，车轮会打滑，甚至使方向失控。同样，汽车在起步或急加速时，驱动轮也有可能打滑，在冰雪等光滑路面上还会使方向失控而出危险。 TCS就是针对此问题而设计的。TCS 依靠传感器探测到从动轮速度低于驱动轮时（这是打滑的特征），就会发出一个信号，调节点火时间、减小气门开度、减小油门、降挡或制动车轮，从而使车轮不再打滑。防止车辆失控甩尾。 TCS可以提高汽车行驶稳定性，提高加速性，提高爬坡能力。原来只是豪华轿车上才安装TCS，现在许多普通轿车上也有。TCS如果和 ABS相互配合使用，将进一步增强汽车的安全性能。
汽车的几种表示法
car [kɑ:] n.车辆,(小)汽车, 电车
auto ['ɔ:təu] n.汽车
automobile [ɔ:təmə‘bi:l] n.汽车;机动车

• 化油器设计成带有喉管的形式，喉管是空气通道中一段狭窄的部分。空气流过化油器的喉管时速度增加，在喷嘴的开口处形成低压区。大气压力作用在储存汽油的浮子室上。燃油便被压入伸向喉管低压区的喷管里。这样燃油从喷管末端喷射到气流中。
• (2) Float Chamber
• The float chamber is a reservoir for storing and supplying fuel to the carburetor. As the engine uses fuel, the float chamber replenishes it automatically. The float chamber works on the same basic principle as the holding tank in a flushing toilet. A float rests on top of the fuel in the reservoir. As fuel is used, the float level drops. When the float drops, a needle valve is opened.
• The main circuits of the carburetor ：
• Idle and Low-Speed Circuit • Main Metering Circuit • Power-Enrichment Circuit • Accelerator (Pump) Circuit • Choke Circuit

• 2. Carburetor
• Complete burn • theoretical requirement - 14.7:1
• Excess-air factor λ: • λ=air mass supplied/ theoretical requirement • 过量空气系数
• 化油器输送的燃油与流经化油器的空气量成一定比例。踩下加速踏板，节气门开度变大，化油器吸入的空气增加。化油器可提供较浓或较稀的混合气，这取决于发动机转速、负荷、温度和油门开度等因素。为满足复杂的要求，化油器的结构也很复杂，其上有很多内部通道和部件。
• (1) Venturi 喉管
• An automobile carburetor is designed with a venturi chamber. The venturi is simply a narrowed portion in the air passage. Air moving through the throat of the carburetor speeds up as it travels through this narrowed passageway. The increased air speed through the venturi creates a lowpressure area at the opening of the fuel nozzle. Atmospheric pressure pushes down on a fuel reservoir within the carburetor known as the float chamber. Fuel is forced through a tube that extends into the lowpressure area of the venturi. Thus, fuel sprays through the end of the tube into the air stream.

• The main function of the carburetor：
• Metering • correct proportions of fuel and air • Atomization • spray of fine particles to great air • Distribution • uniform mixture delivered to manifold
• 2. Carburetor
• A carburetor delivers fuel in proportion to the amount of air flowing through it. As you press on the accelerator pedal, the throttle valve opens wider to draw more air through the carburetor. The carburetor provides richer or leaner mixtures, de油pe门nd开in度g on a number of factors: engine speed, load, temperature, and throttle position. To meet complicated demands, a carburetor is a highly intricate device, with many internal passages and parts.
• 2.6.1 Gasoline :
• Gasoline must vaporize easily. This characteristic, called volatility, is important. However, it must not vaporize too easily, or it will turn to vapor inside the fuel tank or fuel lines. Inside the fuel line, fuel vapor may block the flow of liquid gasoline. This is called vapor lock. Vapor lock is common in fuel lines where the inlet side of the pump is exposed to high temperatures.

2.6 Gasoline Fuel System
• What’s the meaning of the air/fuel ratio (A/F)?
• A/F is stated in term of weight, different fuel has different ratio.
• 在点火前增加燃烧室内可燃混合气的压力有助于提高发动机的功率，这是通过把可燃混合气压缩到一个极小的体积来实现的。高的压缩比不仅增加发动机的功率，而且会带来更多的有效功率。但随着压缩比的增加，爆震的可能性也会增加。
• Two primary standard reference fuels, normal heptane and iso-octane arbitrarily assigned 0 and 100 octane number, respectively, are then blended to produce the same knock intensity as the test sample. The percentage of isooctane in blend is considered the octane number of the test sample. Thus, if the matching reference blend is made up of 15% n-heptane and 85% isooctane, the test sample is rated 85 motor or research octane number, according to the test method used.
