The repair work is far beyond the capability of technicians hands and eyes. As a technician, you will have to use some special facilities to find out the fault cause and solve problems. The

14、se testing equipments that are commonly used in the auto repair work include auto multimeter, auto oscilloscope, fault decoder，engine performances analyzer, auto exhaust gas analyzer and four-wheel alignment instrument, etc.(shown as the figure 2.2.1). They are all the mechanical-electrical integrat

15、ed examining facilities specially designed for automotive trouble diagnosis, test and analysis. The brief introduce is as below.改革創(chuàng)新示范教材12Automobile testing e改革創(chuàng)新示范教材13Automobile testing equipment任務實施The digital auto multimeter. Multimeters are divided into two types：digital and analog. It is an ind

16、ispensable testing instrument in the repair process. Compared with an analog multimeter, a digital multimeter (DMM) has more advantages, like accurate readings, more functions and higher impedance. Therefore most electricians would like to use digital multimeters to test such parameters as current,

17、voltage and resistance. Besides, a more advanced function like frequency or capacitance can be selected to measure.Auto oscilloscope. The oscilloscope is a powerful tool by which automobile mechanics can make a rapid fault diagnosis of the automotive electronic equipment. It is a device that measure

18、s voltages. When tested, the oscilloscope shows a waveform diagram which the voltage changes with the time to respond to an electronic signal. Normally, it displays the voltage as a function of time. Especially, the oscilloscope is applied to observe and measure the frequency, amplitude and waveform

20、splay is sometimes called the Z axis.The oscilloscope is more accurate and more graphic than the multimeter to measure an electronic signal. It mainly consists of the liquid crystal display (LCD), function keys, a host interface and accessories.Auto decoder. When a car is running, once the electrica

21、l control system fails, the electronic control unit (ECU) will use its self-diagnosis function to detect the fault. The fault will be stored in the memory of the electronic control unit in the form of the code. The role of the decoder is to read the fault code from the electronic control unit and pr

22、ovide reference for the maintenance personnel.An auto decoder is divided into general and special type. No matter which it is，its structure is basically the same, mainly including the host, power supply, test connectors and test line.改革創(chuàng)新示范教材15Automobile testing e改革創(chuàng)新示范教材16Automobile testing equipme

An exhaust gas analyzer is one of important testing instruments. A 5-gas analyzer measures carbon dioxide (CO2), carbon monoxide (CO), oxygen (O2), hydrocarbon (HC) and nitrogen oxide (NOx). The gas readings can be used to determine emission compliance, and to diagnose
