* CHAPTER 6 ELECTRICAL SYSTEM SEA * Question 1: List the major parts of a car electrical system. Battery Starter Alternator Ignition Lighting Auxiliary Electronic Device 直流 (D.C.) Direct Current 交流 (A.C.) Alternative Current 1) The purpose of the battery is to store electrical energy. It does this by converting the electrical energy supplied to it into chemical energy so that when an electrical current is required the energy change is reversed. 蓄电池用于储存电能,它将电能转变为化学能储存,在用电时再将化学能转变为电能。 Question 2: List the types of Battery. Positive plate Negative plate Electrolyte inlet 电解液插入端 Dilute H2SO4 稀 Lead-acid Battery Nickel-hydrogen Battery Hydrogen Fuel Cell Lithium-ion Battery Positive plate Negative plate Electrolyte Water Water Acid Acid Can Header Anode阳极 Cathode 阴极 Separator 2) The charging system provides the electrical energy a car needs once its engine starts. The charging system does two jobs. First, it provides electrical power for the ignition system and the cars electrical accessories. Second, it replaces the power used by the battery in starting the car. In other words, the charging system maintains the battery’s state of charge. 一旦发动机起动,充电系统就给汽车提供电能。充电系统有两个任务:首先,给点火系和电力附件提供电能;其次,给电池补充在起步时消耗的电能,换句话说,就是维持电池的荷电状态。 Question 3: List the main parts of Alternator. 电枢 转换器 电刷 Question 4: What’s the operation theory of Alternator? 3) Electricity can be produced by moving a conductor through a magnetic field, The opposite also holds true. By moving the magnetic field and holding the conductor, electricity can be generated in the conductor. This current is called an induced current. This is the basic principle of the alternator, an electromechanical device that changes mechanical energy into electrical energy. 导体在磁场中移动会产生电流,反之电也可以产生磁。保持导体固定不动,移动磁场,导体中就会产生电流,该电流称为感应电流。交流发电机的基本原理就是这样的,通过机电装置把机械能转变为电能。 4) The starter must crank the engine at a specified minimum speed (starting speed) in order to generate the air-fuel mixture necessary for self-sustained operation
