What are the testing equipment for auto parts?

Automobile testing instrument is a device used to test the condition or working ability of automobile. It has multiple systems, and each system has its own commonly used test equipment. In the automobile diagnosis industry, the common automobile detection instruments include engine performance detection and diagnosis instruments and equipment, chassis and vehicle detection and diagnosis equipment, electrical test and detection equipment, electrical test and detection equipment and so on. The function of each inspection instrument is different. Let's take a look at it with Xiao.

What are the automobile testing instruments?

1, engine performance test and diagnosis equipment: engine bench test equipment, engine power test equipment, engine tachometer, cylinder pressure gauge, cylinder leakage detector, engine thermometer, etc.

2. Commonly used chassis and vehicle detection and diagnosis equipment: chassis dynamometer, automobile brake tester, automobile sideslip tester, computer four-wheel locator, etc.

3. Common electrical test equipment: electrical universal test bench, battery detector, headlight detector, pressure gauge, automobile multimeter, test lamp, etc.

4. Detection and diagnosis equipment of electronic control system: engine comprehensive analyzer, decoder, automobile sensor detection, oscilloscope, portable engine ECU tester, etc.

Functions of Common Automobile Testing Instruments

1, automobile multimeter

Automobile multimeter is mainly used to detect parameters such as DC current intensity, DC voltage, AC voltage, wire resistance, etc. It can also be used to detect speed, closing angle, duty ratio (bandwidth ratio), frequency, pressure, time, capacitance, inductance, semiconductor components and temperature.

2, pressure gauge

Pressure gauge is used to measure the pressure of gas or liquid in containers, pipelines and equipment, and it is one of the instruments widely used in automobile maintenance enterprises. Pressure gauges are generally composed of range pressure gauges, connecting hoses, one-way air inlet valves and replaceable joints suitable for various models.

3. Test lamp

The test lamp is used to check whether the system power supply circuit supplies power to electrical components, and can be used for open circuit inspection and short circuit inspection. Commonly used types are 12V test lamp, self-contained power test lamp and so on.

4. Oscilloscope

Oscilloscope is mainly used to trigger and collect signals (waveforms), scale and locate waveforms, and measure waveforms. In automobile maintenance, it is very useful to detect ignition system, exhaust emission analysis and parts quality. When using an oscilloscope, you may need to touch other parts of the system. In order to avoid potential dangers, special attention should be paid to electrostatic discharge (ESD), which may damage the oscilloscope and its accessories. In order to prevent electrostatic discharge, when installing or disassembling sensitive components, you should wear an anti-static grounding wrist strap to discharge your own electrostatic voltage.

5. Portable engine ECU tester

Portable engine ECU tester is mainly used to dynamically test the parameters of engine ECU, which is very convenient to use, small in size and light in weight. Test instruments are usually equipped with fault diagnosis interfaces. Just connect the diagnostic interface with the fault diagnosis socket under the engine compartment or instrument panel, and then operate the key instructions on the control panel of the tester to test the sensors, actuators and their circuits of the engine electronic control system.
