An automotive testing instrument is a device used to detect the condition or working capacity of a car, and it has multiple systems, each of which has its own commonly used testing equipment. In the automotive diagnostic industry, common automotive testing instruments include engine performance testing and diagnostic equipment, chassis and vehicle testing and diagnostic equipment, electrical testing and testing equipment, electrical testing and testing equipment, etc., the role of each inspection instrument is different, and then let's take a look at it with the small.
What are the automotive testing instruments.
1. Engine performance testing and diagnostic equipment: engine bench test equipment, engine power test equipment, engine tachometer, cylinder pressure gauge.
Cylinder leak detector, engine temperature gauge, etc.
2. Commonly used chassis and vehicle testing and diagnostic equipment: chassis dynamometer test bench, automobile brake test bench, automobile sideslip test bench, computer wheel aligner, etc.
3. Commonly used electrical test and testing equipment: electrical universal test bench, battery tester, headlamp tester, pressure gauge, automobile multimeter.
test lights, etc. 4. Electronic control system testing and diagnostic equipment: engine comprehensive analyzer, decoder.

In addition to parameters such as DC voltage, AC voltage and resistance of the wire, it can also be used to detect the rotation speed, closure angle and duty cycle.
bandwidth ratio), frequency, pressure, time, capacitance, inductance, semiconductor components, temperature, etc.
2. a pressure gauge.
Pressure gauge is used to measure the pressure of gases or liquids in containers, pipelines and equipment, and is one of the instruments widely used by automobile maintenance enterprises. The pressure gauge is generally composed of a measuring pressure gauge, a connecting hose, a one-way inlet valve and a replaceable joint suitable for various models.
3. Test lamp.
The test light is used to check whether the system power supply circuit provides power to the electrical components, and can be used for open circuit inspection and short circuit inspection, and the commonly used types are 12V test lights, self-contained power test lights and so on.
4. an oscilloscope.
The oscilloscope is mainly used to trigger and collect signals (waveforms), zoom and position the waveforms, measure the waveforms, etc., and are very useful for detecting ignition systems, exhaust emission analysis, and part quality in automobile maintenance work. When using an oscilloscope, it may be necessary to have access to other parts of the system, and to avoid potential hazards, special attention should be paid to electrostatic discharge (ESD) that can damage the oscilloscope and its accessories. In order to prevent electrostatic discharge, when installing or disassembling sensitive components, you should wear an anti-static iron wrist strap to release your own electrostatic voltage.
5. Portable engine ECU tester.
The portable engine ECU tester is mainly used for dynamic testing of the parameters of the engine ECU, which is very convenient to use, small in size and light in weight. The test instrument is generally equipped with a fault diagnosis interface, which is simply connected to a fault diagnosis socket in the engine compartment or under the instrument panel, and then the tester control panel is operated.
The sensors, actuators and circuits of the engine's electronic control system can be detected.

The inspection content of auto parts mainly includes the following aspects:
1.Specification and size inspection: Check the specifications and dimensions of the parts to ensure that the parts meet the design requirements and accuracy requirements.
2.Appearance inspection: check the surface quality of the parts, including surface flatness, finish, no cracks, burrs, etc.
3.Functional Inspection Register: Check the function of the part to ensure that it can work properly.
4.Material Inspection: Inspect the materials of the parts to ensure that the materials meet the design requirements and quality standards.
5.Durability inspection: The durability of parts is inspected, including service life, fatigue life, etc.
6.Safety inspection: check the safety of the parts to ensure that the parts will not cause harm to people and property during use.
7.Environmental protection inspection: check the environmental performance of the parts to ensure that the parts will not cause pollution and damage to the environment.
The above is the common inspection content of automobile parts, and the specific inspection content and method will also vary according to different parts types and use scenarios. When inspecting parts, attention should be paid to selecting appropriate inspection standards and inspection methods to ensure that the inspection results are accurate and reliable, so as to ensure the quality and safety performance of auto parts.

1) Check the vehicle model, brand, factory number, body (chassis) and engine model and factory number, license plate number of the vehicle submitted for inspection.
2) Check the DAO body appearance of the car. The appearance of the vehicle should be neat, the parts should be in good condition, the connection should be fastened, and there should be no defects; 3) Inspection of water leakage and oil leakage. When the engine is stopped and stopped, there shall be no obvious water leakage phenomenon in the water tank, water pump, cylinder block, cylinder head, heating device and all connecting parts, so that the motor vehicle shall not be less than 10 km, and there shall be no obvious oil leakage phenomenon after stopping for 5 minutes.
4) Engine inspection. The engine should have good power performance, stable operation, stable idle speed, no abnormal noise, and normal oil pressure; The engine should have good starting performance.
5) Steering system inspection. The steering wheel should rotate flexibly, be easy to operate, and have no blockage. During the wheel steering, there shall be no interference with other components.
6) Brake system inspection. The brake system should be durable and not damaged by vibration or shock. The free stroke and pedal force of the brake pedal of the service brake system shall meet the relevant technical conditions of the vehicle.
7) Inspection of lighting, signaling devices and other electrical equipment. Lamps and lanterns should be installed firmly, intact and effective; All lights should be installed securely and freely.

Generally, we divide the automobile inspection into three parts: vehicle testing, engine testing and chassis and body testing, including the following items:
1. Engine testing
a.Technical condition of the cooling system. b.
the technical condition of the oil supply system; c.technical condition of the lubrication system; d.the technical condition of the ignition system; e.
the technical condition of the start-up system; f.abnormal engine noise; g.engine sealing performance; h.
fuel consumption; i.engine power;
2. Vehicle inspection:

Wheel alignment includes front wheel alignment (amount of side slip) and rear wheel alignment; e.Technical condition of the brake system: 1
Braking distance 2braking force; 3.Braking deceleration.
f.Technical condition of the steering system: The steering wheel includes free travel and steering force.
g.Technical condition of the drive train: 1

1. Prevent overheating.
In order to prevent the engine from overheating, it should be noted that the fan belt should not be touched with oil during maintenance to prevent slipping, and the belt should be kept tight. During long-distance driving, you should pay attention to taking a break at the right time, choose a cool place as much as possible when resting, and open the hood for ventilation and heat dissipation. When the tire pressure increases due to heat, you should stop immediately to cool down, otherwise there is a risk of puncture, pay special attention not to use the method of deflating or pouring cold water to reduce the tire pressure and temperature. >>>More
