翻译_汽车工程专业英语第一章汽车基础当今的汽车一般都由15000多个分散、独立且相互配合的零部件组成。
这些零部件主要分为四类：车身、发动机、底盘和电气设备。
Body：车身Engine：发动机Brakes：制动器Power train：传动系Steering：转向系Electrical：电器及电子设备Suspension：悬架Layout of a passenger car：乘用车总布置Layout of a commercial vehicle：商用车总布置1.1 车身汽车车身是由车窗、车门、发动机罩和行李箱盖焊接在金属板外壳内而成。
金属板外壳将发动机、乘客和货物覆盖以提供保护。
车身的设计要保证乘客安全舒适。
车身的款式使得汽车看起来漂亮迷人、色彩斑斓、时尚前卫。
私家轿车有一个封装起来的车身，4个大车门允许乘客进出车厢。
这个设计也可放置行李或其他货物。
私家轿车也可以称为拥有固定车顶的传统车辆。
有许多类似车身设计的活顶式车除了拥有两个车门，其他的设计和敞篷车大致一样。
皮卡或载重汽车。
通常它们有比轿车大的底盘和悬架来支撑重物质量。
型运载货车基于轿车的设计并改装以便腾出最大限度的空间来装载货物。
商用运载货物车辆的车身是专用设计的。
如罐车运载液体，自卸车搬运泥土或大批谷物，平板车和货车通常用来运载普通货物。
公交车或长途汽车通常是4轮固定模式的车辆，但会用到大量的车轮和轮轴。
有时，铰接式公交车是为了增加容量。
公交车和货车可以做成单层或双层的。
长途汽车常用于长距离运载，且费用比较昂贵，因此市区里就会用到公交车，如市郊间上下班时用于交通运输。
1.2 发动机发动机作为动力装置。
最常见的内燃机通过燃烧发动机气缸里的液体燃料而获得能量。
内燃机有两种类型：汽油机（又称为点燃式发动机）和柴油机（又称为压燃式发动机）。
两种类型均称为热力发动机。
燃烧燃料产生的热量使汽缸里气体的气压增加并提供能量通过传动轴连接到传动系统。
发动机气缸的排列方式称为发动机配置。

Starting with the first patented gasoline-powered Benz Motorwagen in 1886(Figure 1.1)，the automotive industry has seen continuous and exciting changes for over a century. The early gasoline-powered automobile generated 1.5hp(1.1kW)，it reaches top speed of 3~5mph(5~8km/h).Today's average vehicles have 110~450hp(80~330kW )engines and cruise at 106~120km/h，depending on the legal speed limit. For many people around the world，automotives are the most important means of personal transportation.汽车工业影响经济的许多领域。

①传动系将动力传到驱动轮②转向系控制着汽车的方向③悬架和轮子缓冲来自路面的振动④制动系减缓或制动汽车15.the spark-ignition engine is an internal-combustionengine with externally supplied in ignition,which convertsthe energy contained in the fuel to kinetic energy 火花点火式发动机是一种内部与外部的点火器，将燃料中的能量转换为动能16.intake valve 进气阀 exhaust valve 排气阀 specificfuel consumption 燃油消耗率swept volume 有效容积engine capacity 发动机排量 compression ratio 压缩比17.Excess-air factor: 错误！未找到引用源。
=Air masssupplied / Theoretical requirement.（过量空气系数：错误！未找到引用源。
=实际进气量/理论要求空气量）18.the flammability of gasoline varies with its quality andthe additives mixed with the gasoline,the way gasoline burnsinside the combustion chamber is most important 汽油的燃烧随汽油质量和添加剂混合而变化，汽油燃烧，在燃烧室是最重要的途径19.The combustion process in the cylinder is influenced notonly by fuel management, mixture quantity and air-fuel ratio,but also by the ignition advance and the energy containedin the ignition spark.（发动机气缸中的燃烧过程不仅受到喷油量、混合气量和空燃比的影响，而且也受到点火提前角的火花能量的影响。
）20.because a specific ignition advance angle and a specificinjection time correspond to each point of the engine speed load map, 因为一个特定的点火提前角和一个特定的注射时间对应的发动机转速负荷图中的每一点，it is important that all variables which pertain to the same point are calculated on the same speed/load area更重要的是，所有的变量都归于同一点的计算是基于相同的速度或负荷区21.The exhaust-gas recirculated back to the combustionchamber thus serves to reduce the peak combustion temperature. Since formation of oxides of nitrogen increases super proportionally with the combustion temperature, EGR as a tempera-tune-reducing measure is a very effective method of reducing oxides of nitrogen.（废气再循环回到燃烧室中可使燃烧最高温降低。
因为数据显示，NOx随燃烧温度升高而增加，所以EGR就成为一种通过降低燃烧最高温减少NOx排放的有效措施。
）22.the idle speed control is realized by means of data fromthe ignition system and the fuel injection systen and is part of the overall system of control which includes tank ventilation and camshaft control怠速控制是通过从点火系统和燃油喷射系统和数据的一部分是整个系统的控制，包括油箱通风和凸轮轴控制23.gasoline direct injection(GDI)汽油直接喷射 SPI单点喷射 MPI多点喷射24.ECU: electronic control unit电子控制单元 air/fuelratio空燃比 throttle valve节气门weak mixture:稀混合气 rich mixture:浓混合气 advance angle 提前角25.The more air is compressed, the higher will be itstemperature.（压缩的空气越多，气缸内温度越高。
）26..To get the high temperatures needed to ignite the dieselfuel, higher compression ratios are needed.（为得到可点燃柴油的温度，需要更高的压缩比。
）27.the necessity of reducing consumption and the tighteningof noxious emissions legislation at the end of the eighties, added more weight to the trend towards highly charged enginesin the commercial vehicle as well as the passenger car sector ,with the aid of the turbocharger,it was possible to considerable increase the efficiency of the engines and simultaneously reduce noxious emissions .（80年代减轻有害废气的有必要的方法只能是加强客运客车发动机负载量或者商业车的。
