Lesson 2 Internal Combustion Engine (PartⅠ)
manifold n.[化]歧管,支管,导管
❖ introduce:介绍,引荐;引进;输入,传入
❖ 由于燃料在发动机气缸内燃烧,因此发动机被称为内部燃烧发动机。在 内燃机中,空气和燃油的混合物被引入一个封闭的气缸,在气缸内空气 和燃油的混合物先被压缩,然后被点燃。
❖ The burning of the fuel (combustion) causes a rapid rise in cylinder pressure which is converted to useful mechanical energy by the piston and crank-shaft.
vacuum:真空,真空度
revolution:革命,循环,周期
sectional:截面的,剖面的;部分的,局部的

Lesson 2 Internal Combustion Engine (PartⅠ)
v. bore a hole
venturi n .缩喉管
jet n.喷嘴
throttle n.节流阀
depression n.降低,下降,衰减
pivot n.枢轴,支点
vi,在枢轴上传动;vt.装枢轴于
tilt v.倾斜,翻转
principle:原则,原理;准则,道义 principal:主要的,首要的
❖ 发动机是一个独立的动力装置,它把燃料燃烧产生的热能转变成机械能, 从而推动车辆运行。
❖ Because fuel is burned within, the engine is known as an internal combustion (IC) engine. In the IC engine, an air-fuel mixture is introduced into a closed cylinder where it is compressed and then ignited.
❖ give rise to:引起,使发生 ❖ giving rise to: 得到…结果(状语,直译:这样,从而,因此,使) ❖ classification:分类,分级,类别源自文库❖ 燃油可以由火花或者通过压缩点燃,从而分为火花点燃式和压燃式两种
类型的发动机。
❖ An sectional engine view of a typical spark ignition petrol engine is shown in Fig.2.1, detailing the major components.
n.复印本,多种;a.多种的;v.复写,增多 eg. manifold effect
inlet n.进气,入口
inlet valve n.进气阀
induction n.引入,诱导,感应,进气
exhaust v.;n.排出;排气(口),废气
exhaust valve 排气阀
stagger v.交错
bore n.孔
