Ultra-lean Combustion Mode. Under most normal driving
Chapter 2 Internal Combustion Engine 2.7 Gasoline direct injection
Two main operating modes of Volkswagen AG's fuel stratified injection (FSI) which uses more operating modes and FSI’s fuel-saving potential is shown in Figure 2-16. A typical pulse injection system with direct injection is given in Fig.2-17.
Chapter 2 Internal Combustion Engine 2.7 Gasoline direct injection
conditions, up to speeds of 120 km/h, the Mitsubishi GDI engine operates in ultra-lean combustion mode, resulting in less fuel consumption. In this mode, fuel injection occurs at the latter stage of the compression stroke and ignition occurs at an ultra-lean air-fuel ratio of 30-40. This operating mode is also called as stratified-charge mode. Superior Output Mode. When the GDI engine is operating with higher loads or at higher speeds, fuel injection takes place during the intake stroke. This optimizes combustion by ensuring a homogeneous, cooler air-fuel mixture which minimizes the possibility of engine knocking. This mode is also called as homogeneous-charge mode.

第1单元汽车基础课文A 汽车的基本组成今天的一般汽车含有15000多个相互独立的零件,这些零件必须相互配合才能工作。

这些零件可以被划分为四大类:发动机、车身、底盘和电气设备。

1.发动机发动机是汽车的动力装置。

内燃机是最常见的动力装置,它使燃料在气缸内燃烧,从而获得动力。

发动机有两种类型:汽油机(也叫做点燃式发动机)和柴油机(也叫做压燃式发动机)。

这两种发动机均被称为热机。

燃料的燃烧产生了热量,这将导致气缸内的气体压力的升高,从而带动与变速器相连接的一根轴旋转。

所有的发动机都设有燃料供给系统、排气系统、冷却系统和润滑系统。

汽油机还设有点火系统。

点火系统的作用是提供点燃气缸内的空气-燃油混合气必须的电火花。

当点火开关接通时,电流从12V蓄电池流到点火线圈。

点火线圈将电压提高,以便产生点燃燃料所必须的20000V的高电压。

汽车通过其电气系统提供它所需要的全部电流。

例如,汽车电气系统要为点火系统、喇叭、车灯、加热器和起动机提供电流。

电压的高低由充电系统来维持。

燃料系统贮存液体燃料,并将液体燃料输送给发动机。

燃料贮存在燃油箱内,燃油箱通过燃油管与燃油泵相连。

在燃油泵的作用下,将燃料从燃油箱吸上来,并通过燃油管,穿过滤清器,到达化油器(在这里,燃料与空气进行混合),或者进入燃油喷射系统。

燃料在化油器内、进气歧管内或者就在各个气缸内与空气混合,从而形成了可燃混合气。

冷却系统将多余的热量从发动机上搬走。

发动机燃烧室内的温度约为2000℉(1094℃)。

由于钢铁在大约2500℉(1354℃)时就会熔化,为了防止发动机损坏,必须将这些热量移走。

散热器内充满冷却液,水泵将使这些冷却液反复通过发动机气缸体和气缸盖内的空心薄壁层。

冷却液不停地流过发动机和散热器,从而将发动机的热量散发出去。

也可以通过散热器风扇将热量散发掉,因为风扇能使空气从散热器叶片的狭小缝隙中穿过。

冷却系统还能为乘客舱和车窗除霜器提供热量。

润滑系统对保持发动机平稳运转极为重要。

Chapter 4 Steering and Suspension Systems
4.1 Steering System
4.1.2 Types of Steering System There are two types of steering systems: manual steering and power steering systems. In the manual steering systems, driver does all the work of turning the steering wheel, steering gear, and tires. In the power steering systems, hydraulic or electric power-assisted steering is used to reduce the effort required by turning the steering wheel. There are three types of the steering gears in use: recirculating ball steering gear, worm-and-roller steering gear and rack-and-pinion steering gear. 4.1.3 Power Steering Systems Hydraulic lack-and-pinion power steering system. This system consists of mechanical rack-and-pinion steering gear, hydraulic working cylinders with working plungers, rotary slide valve, oil pump, pressure-limiting valve and oil reservoir (Figure 4-2).

The clutch side is machined smooth to provide a friction surface. Holes are drilled into the flywheel to provide a means of mounting the clutch assembly. A hole is usually drilled directly into the rear of the crankshaft. This hole allows a bearing to be installed in the center of the flywheel.
Both sides of its outer edge are covered with friction material. It is often made of asbestos or other high temperature material and copper wires either woven or molded together. It is riveted to the disc.
The clutch pressure plate disc is the same in each type of pressure plate assembly. It is made of a thick piece of cast iron for maximum heat absorption. It is round and about the same diameter as the clutch disc. One side of the pressure plate is machined smooth. This side will press the clutch disc facing area against the flywheel. The outer side has various shapes to facilitate attachment of springs and release mechanisms. Release Lever Operating Mechanism

The way engine cylinders are arranged is called engine configuration. In-line engines have the cylinders in a line. This design creates a simply cast engine block. In vehicle applications, the number of cylinders is normally from 2 up to 6. Usually, the cylinders are vertical. As the number of the cylinders increase, the length of the block and crankshaft can become a problem. One way to avoid this is with a V configuration. This design makes the engines block and crankshaft shorter and more rigid. 发动机的布置即发动机气缸的排列方式。 发动机缸体按直线排列的即直列式,这种布置使 得发动机缸体结构简单。汽车发动机一般为 2~6 缸,通常气缸是垂直放置的,但气缸数量的 增加会导致缸体和曲轴的长度过大,解决问题的措施之一就是采用 V 型布置,这种布置方 式可以使发动机缸体和曲轴长度尺寸更短,从而大大增加刚度。
