Battery
The automotive battery, also known as a lead-acid storage battery, is an electrochemical device that produces voltage and delivers current. In an automotive battery we can reverse the electrochemical action, thereby recharging the battery, which will then give us many years of service. The purpose of the battery is to supply current to the starter motor, to provide current to the ignition system while cranking, to supply additional current when the demand is higher than the alternator can supply and to act ad an electrical reservoir.
Ignition Switch
The ignition switch allows the driver to distribute electrical current to where it is needed. There are generally 5 key switch positions that are used.
1. Lock
All circuits are open (no current supplied) and the steering wheel is in the lock position. In some cars, the transmission lever cannot be moved in this position. If the steering wheel is applying pressure to the locking mechanism, the key might be hard to turn. If you do experience this type of condition, try moving the steering wheel to remove the pressure ad you turn the key.
2. Off
All circuits are open, but the steering wheel can be turned and the key cannot be extracted.
3. Run
All circuits, except the starter circuit, are closed (Current is allowed to pass through). Current is supplied to all but the starter circuit.
4. Start
Power is supplied to the ignition circuit and the starter motor only. That is why the radio stops playing in the start position. This position of the ignition switch is spring loaded so that the starter is not engaged while the engine is running. This position is running. This position is used momentarily, just to activate the starter.
5. Accessory
Power is supplied to all but the ignition and starter circuit. This allows you to play the radio work the power windows, etc. while the engine is not running.
Most ignition switches are mounted on the steering column. Some switches are actually two separate parts:
The lock into which you insert the key. This component also contains the mechanism to lock the steering wheel and shifter.
The switch which contains the actual electrical circuits. It is usually mounted on top of the steering column just behind the dashboard and connected to the lock by a linkage or rod.

电池
汽车电池，又名铅酸蓄电池，是一种可以产生电压和电流的电化学装置。在汽车电池中，我们可以利用可逆的电化学反应为电池充电，使我们获得更长的电池使用寿命。电池的用途是给启动电机供电，进而激励点火系统。此外，当能量输出需求超过交流发电机的供能上限时，汽车电池还可为系统提供额外的电力支持，在汽车系统中，蓄电池扮演着“电能存储器”的角色。
点火开关
点火开关允许驾驶者将电流分配到需要它的地方，大体来说，有5种常用的电键位置。
1. 锁止位（Lock）
所有电路均为开路（即无电流通过），方向盘也处于锁定状态。在一些轿车中，变速杆在这个位置上无法被移动。如果此时方向盘正在对锁止机构施力，钥匙将很难被转动。如果你真的遇到这种情形，试着转动方向盘，撤除扭力，然后再转动钥匙。
2. 关闭位（Off）
所有电路均为开路，方向盘可以被转动，但钥匙无法被取出。
3. 运行位（Run）
除启动电路以外，所有电路均闭合（即允许电流通过），电流将被输送到除了启动电路以外的全部电路。
4. 启动位（Start）
仅向点火电路和启动电机供电。这就可以解释为什么在启动位置时，车载广播会停止工作。点火开关的这个位置由受载弹簧控制，所以在发动机运行时，启动电机是不工作的。这个位置是动态的、瞬时使用的，只是为了激活启动电机。
5. 辅助位（Accessory）
向除了点火线路和启动电机之外的电路供电。这个位置允许你在引擎熄灭的时候收听广播、使用电动车窗等等。
大多数点火开关都被安装在驾驶杆上，一些开关则被分成了两个独立的部件：
用来插拔钥匙的车锁。这个组件也包含锁定方向盘和变速拨叉的机械结构；
包含实际电路的开关。它通常被安装在驾驶杆的顶部、仪表盘的正后方，通过一个铰链或杆件与车锁相连。
转速
大多数系统都测量点火线圈测速脉冲或曲柄触发式磁/霍尔效应传感器的转速。转速
被认为是所有电喷系统的主要输入信号。大多数系统为每个测速脉冲生成注入脉冲，因此随着转速的增加，注入脉冲的频率也增加。
气流
MAF
型系统中气流也是一个主要的输入信号。X量的空气需要Y量燃料。随着转速和节气门开度的增加，气流上升到一个点。
歧管压力
速度密集型系统中，歧管压力是和转速信号结合计算气流的基本输入信息。节气门打开后，歧管压力增加，将需要更多燃料。
