然侧向力FＲy 作用于汽车重心时，由于α Ａ ＜α Ｂ ，汽车将朝侧向力 的相反方向偏转，如图所示。离心力FＣ 的侧向分力FＣy 总是与FＲy 同向，使侧向偏离增加，Rα 减小，离心力再增加使Rα 进一步减小。 如果车速达到或超过临界车速，这种恶性循环的不断进行将导致汽车侧

第二节 汽车的操纵稳定性
一、汽车操纵稳定性的评价指标 通常认为汽车的操纵稳定性包含互相联系的两个部分：一是操纵性，二
３．过多转向 若前轮的侧偏角小于后轮的侧偏角，即α Ａ＜α Ｂ,则Rα ＜R， 称为过多转向。具有过多转向特性的汽车有如下的行驶特点： （１） 当转向盘转角固定不变，汽车以不同的固定车速行驶时，其 转向半径小于具有刚性车轮的汽车在同样条件下的转向半径，并且车速 增高时转向半径减小，当转向盘转角固定，汽车加速行驶时，随车速的 提高，其转向半径将越来越小，最后导致汽车侧滑。 （２） 为使过多转向的汽车沿给定半径的圆周行驶，其所需转向轮 转角应随车速的提高而减小，即驾驶员应随车速提高不断减小转向盘转 角。当行驶速度达到某一数值时，其转向盘和转向轮应返回到中间位置， 此车速称为临界车速。过多转向的汽车达到临界车速时，只要有微小的 转向轮转角也将导致极大的横摆角速度（汽车绕转向中心转动的角速 度），这将意味着转向半径越来越小，汽车发生急转，故过多转向的汽 车有失去稳定性的危险。
是稳定性。操纵性是指汽车能够准确地响应驾驶员转向指令的能力，稳定性 是指汽车受到外界扰动（路面扰动或突然阵风扰动）后恢复原来运动状态的 能力，两者很难断然分开。稳定性好坏直接影响操纵性的好坏，因此通常只 笼统地将两者称为操纵稳定性。

Piston
• (1) Provide a moving seal for the combustion chamber against the crankcase. • (2) Absorb [əb'sɔ:b] the gas pressure generated during combustion and transmit it to the crankshaft via['vaiə] the connecting rod .
Piston
• The Engine Piston receives the pressure from the burning air-fuel mixture and converts this pressure into reciprocating [rɪ'sɪprə,keɪt] motion. Pistons serve several['sevrəl] purposes['pə:pəs]:
Crankshaft
• The crankshaft is the main rotating member of the engine. Connecting rods are attached to the crankshaft. This is where reciprocating energy is converted to rotating energy.
The Timing Gear
• The timing gear, in most engines is housed in a special case fitted at the front end of the engine. • The engine timing gear controls the moment and the duration of the intake of fresh gases and the moment and the duration [djuə'reiʃən] of the discharge of exhaust gases.

Intermediates
Also called mid-sized cars, intermediates provide what many consider to be the best trade-off between economy and comfort. Parking maneuverability and fuel economy are superior to the full-size models, while maintenance access, roominess and long-trip comfort are better than those of the compacts and subcompacts. Intermediates have room for five adults and a large trunk (boot). Engines are more powerful than compact cars and 6-cylinder engines are more common than in smaller cars. Car sizes vary from region to region; in Europe, large family cars are rarely over 4700 mm long, while in North America they may be well over 4800 mm.

U3-课文A-汽车专业英语
第三单元发动机系统简介课文A 润滑系统和冷却系统润滑系统发动机润滑系统(见图3-1)的作用是将洁净的机油以合适的温度和压力输送给每个发动机的运动部件，以减少部件表面相互接触产生的摩擦。
润滑系统的主要部件如下：机油泵是润滑系统的关键部件。
它的任务是产生足够高的压力以抽取油底壳中的机油并使其在整个系统中循环。
在大多数汽车上，有两种常见的机油泵：齿轮式和转子式，如图3-2所示。
集滤器(图3-3)位于油底壳底部，与机油泵相连。
其任务是在机油进入机油泵之前先过滤出油液中的大颗粒脏物。
机油滤清器(图3-4)是润滑系统中非常重要的部件。
它吸附脏油，去除杂质并使其留在过滤介质上，然后将洁净的机油送回到发动机中。
油底壳(图3-5)是安装在曲轴箱下面的一个容器，用于储藏机油。
当发动机静止时，油底壳可将曲轴箱四周流淌下来的机油收集起来。
机油(图3-6)在发动机中起着重要作用：润滑发动机运动部件以减少摩擦；将炽热的发动机部件产生的热量带走，使其冷却；去除发动机部件上的脏物和沉积物。
另外，它还在气缸壁和活塞环之间起着密封的作用，提高发动机压缩性能。
在现代发动机设计中采用两种润滑方法相结合：压力润滑和飞溅润滑(见图3-7)。
冷却系统冷却系统的作用是消除发动机产生的过热；保持发动机在最有效的温度下运行；使发动机起动后尽快热机，达到有效的工作温度(见图3-8)。
冷却系统的主要部件如下：散热器(图3-9)的目的是散发冷却液吸收发动机的热量。
它是由散热器芯、载水管、进水箱和出水箱组成的。
通常散热器安装在发动机舱前部、格栅的后面。
散热器风扇(图3-10)的目的是在汽车行驶时，或者汽车停止行驶而发动机运转时，使气流通过散热器。
通常在散热器的后面安放两个风扇。
水泵(图3-11)是个简单的装置，只要发动机在运转它就要保持冷却液流动。
水泵是由发动机通过正时传动带来驱动的。
压力盖(图3-12) 的目的是保持冷却系统的压力。
如果压力上升到超过设定的压力点，压力盖上的弹簧卸载阀会将压力释放到膨胀水箱中，以防冷却液的缺失。

It is easier for your motor to push a light car than a big, heavy one.原来的意思是“你的马达超过大 推动一辆轻的汽车是比较容易的, 重的”。看懂句子后翻 译为“汽车轻便，那么发动机带动时比较容易，而汽车笨 重，则带动比较困难”。 你不会愿意让你的车子笨重不堪吧。汽车轻便，那么发动 机带动时比较容易，而汽车笨重，则带动比较困难。对汽 车而言，重要的是高效率，而且，你更不愿意浪费能量。
