3、ric System项目内容Part 1Automotive Electric System项目内容The coil pack includes the separate ignition coils and an ignition driver module. The number of ignition coils is exactly half the number of engine cylinders. Each coil provides a spark for two of the cylinders. This is arranged by connecting each en

Part 1Automotive Electric System项目内容The starting system includes the battery, starter motor, solenoid, ignition switch, and in some cases, a starter relay. Part 1Automotive Electric System项目内容Cut-away view of a typical starter systemP

5、art 1Automotive Electric SystemThe starting of the engine signals the driver to release the ignition key from the start position, stopping the flow of current to the solenoid or relay. 项目内容The charging system provides electrical energy for all the electrical components of the vehicle.

6、ve Electric System项目内容Stopping a car in a hurry on a slippery road can be very challenging. Antilock braking systems (ABS) take a lot of the challenge out of this sometimes nerve wracking event.Part 2Automotive Active Safety Systems项目内容High performance has a tendency to understeer or oversteer. ESC,

7、 as electronic stability control is often known, can help correct both of these situations.Part 2Automotive Active Safety Systems项目内容Using all the modern electronic systems at its disposal, the ESP can activate one or more individual brakes, depending on which wheel can increase driving safety the m

10、raking System Types借助专业词典，对ABS资料进行中英文互译。拓展材料拓展内容拓展材料Anti lock braking systems use different schemes depending on the type of brakes in use. We will refer to them by the number of channels that is, how many valves that are individually controlled and the number of wheel speed sensors.u Four-channel,

11、Four-sensor ABSThis is the best scheme. There is a wheel speed sensor on all four wheels and a separate valve for all four wheels. With this setup, the controller monitors each wheel individually to make sure it is achieving maximum braking force.请借助专业词典，翻译上述资料拓展材料u Three-channel, Three-sensor ABSTh

12、is scheme, commonly found on pickup trucks with four-wheel ABS, has a wheel speed sensor and a valve for each of the front wheels, with one valve and one sensor for both rear wheels. The wheel speed sensor for the rear wheels is located in the rear axle. This sys tem provides individual control of t

13、he front wheels, so they can both achieve maximum braking force. The rear wheels, however, are monitored together; they both have to start to lock up before the ABS will activate on the rear. With this system, it is possible that one of the rear wheels wil lock during a stop, reducing brake effectiv

14、eness.请借助专业词典，翻译上述资料拓展材料u One-channel, One-sensor ABSThis system is commonly found on pickup trucks with rear-wheel ABS. It has one valve, which controls both rear wheels, and one wheel speed sensor, located in the rear axle.This system operates the same as the rear end of a three-channel system. Th

15、e rear wheels are monitored together and they both have to start to lock up before the ABS kicks in. In this system it is also possible that one of the rear wheels will lock, reducing brake effectiveness.This system is easy to identify. Usually there will be one brake line going through a T-fitting to both rear wheels. You can locate the speed sensor by looking for an electrical connection near the differential on the rear-axle housing.请借助专业词典，翻译上述资料拓展材料 谢谢观看！
