when

the

vehicle

roundsa curve or suddenly stops,baffle plates are attached to the inside of the tank

当车辆转弯或突然停车时，为了加固油箱也为了防止燃油波动，汽油箱内（通常）有挡

er to limit the transmission of frame distortion to the tank giving rise to squeking as

，

The charging syetem does two jobs :Firstly ,it provides

electrical

power

for

the

ignition

system

and

the

car's

other

electrical

accessories .Secondly ,it supplements the power used by the battery when staring the

order words,the charging system maintains the battery's state of charging

充电系统担负两 项任务

;

第一，它为点火系统及汽车其他电器元件提供电能，第 二，他

提供蓄电池所需的能量。换句话说，充电系统维持着蓄电池的充电状态。

9.A

basic

ignition

system

consists

of

the

battery,low-tension

coil

and

cables,the

ignition

coil,the distributor,high-tension coil and cables,spark plug cables and spark plugs.

一个基本的点火系统包 括蓄电池、低压线圈电缆、点火线圈、分电器、高压线圈电缆、

火花塞电缆和火花塞。< /p>

contains two basic electrical circuits:the primary circuit(low-vol

tage

circuit)and

the

secondary

circuit(high-voltage

circuit).The

primary

circuit

consists

of

the

battery,ignition

switch,resistance

wire,ignition

coil

primary

winding,distributor contact point and connecting secondary circuit consists of the

ignition

coil

secondary

winding,distributor

cap,distributor

rotor,spark

plug

and

spark

plug

wire.

它包含两个基 本电路：一次电路（低压电路）和二次电路（高压电路）

。一次电路由蓄

电池、点火开关、电阻线、点火线圈一次绕组、分电器出头和连接线组成。二次电路由

< br>点火线圈二次绕组、分电器盖、分电器转子、火花塞和火花塞线组组成。

purpose of the ignition switch is to connect and disconnect the ignition system with

the battery, so the engine can be started and stopped as desired.

点火开关的作用 就是将点火系统与蓄电池进行连接或者断开，

从而使发动机能够按照人

< br>的意愿起动或停止。

solenoid

allows

battery

current

to

flow

directly

from

the

battery

to

the

starter

motor,which in turn cranks the engine.

电磁线圈允许蓄电池电流直接从蓄电池流至起动机，从而驱动发动机运转。

the cooltant temperature falls below this pri-set temperature,the thermostat blocks the

coolant flow to the radiator,forcing the water instead through a bypass directly back to the

engine.

如果冷却水温度低于设定温度，

恒温器组织冷却水流入散热器，

迫使冷却水从旁道回流

到发动机。

engine lubrication system supplies oil to all the friction surfaces between the engine

moving parts.

润滑系统为全部传动件的摩擦表面提供润滑油。
