What parts does the engine comprehensive performance detector consist of?

1. Engine temperature performance detection: including detection of coolant temperature, engine oil, transmission oil temperature, etc.Measurement of the starting system of the auto diesel engine: including starting voltage, starting current, absolute cylinder pressure, relative cylinder pressure, battery pressure drop, starting speed, starting voltage waveform, current waveform and cylinder pressure waveform.

2. Engine temperature performance test: including the detection of coolant temperature, engine oil, transmission oil temperature, etc. Measurement of the starting system of the auto diesel engine: including starting voltage, starting current, absolute cylinder pressure, relative cylinder pressure, battery pressure drop, starting speed, starting voltage waveform, current waveform, cylinder pressure waveform.

3. II) The basic structure and working principle of the engine comprehensive performance tester: the engine comprehensive performance tester generally consists of three parts: signal extraction system, information processing system and data acquisition and control display system. The function of the signal extraction system is to pick up the signal of the measured point, and the information processing system preprocesses the collected signal.

4. The engine comprehensive performance detection device has different forms, but a fully configured detector with good performance is nothing more than three major parts: signal extraction system, information processing system and control display system.

5. What are the engine performance testing and diagnostic instruments and equipment of automotive testing instruments: engine bench test equipment, engine power test equipment, engine tachometer, cylinder pressure gauge, cylinder leakage detector, engine thermometer, etc.

How to download the car engine computer detector

1. It is not recommended to download it here. Because you want to download it to your laptop, you need to buy a set of detection data and detection harness of your car first. Moreover, after downloading and installing, non-professionals may not be able to use it well, and the software needs to be upgraded regularly, which is more troublesome in the later stage. X431 is a good machine, but it also needs to be used after learning.

2. You can't download that thing. It's sold in car tool stores, and they are all common to electric injection diesel engines. The special ones for Weichai have to be purchased from Weichai.

3. Plug the plug into the obd interface of the car.Press the one-button start button of the car to turn on the power. Click the same icon as the car brand. Click to confirm in the lower right corner. Choose the first 16-pin option. Click Automatic Search, and the system will find the model of the vehicle.

4. The function of the automobile fault detector can realize the dialogue with the ECU of various electronic control devices in the vehicle through CAN and LIN communication modules, and transmit fault code and engine status information.

5. Specific operation steps: open the driver's side door. Step on the parking brake of the vehicle to avoid slipping. Connect the car diagnostic computer plug to the OBD interface of the vehicle. Press the one-button start button to turn on the car power supply. At this time, the car diagnostic computer will display the car fault code.

Testing equipment to be equipped in automobile repair factories

1. Engine performance testing and diagnostic instruments and equipment: engine bench test equipment, engine power testing equipment, engine tachometer, cylinder pressure gauge, cylinder leakage detector, engine thermometer, etc.

2. [Pacific Automobile Network] Automobile maintenance and testing equipment: maintenance equipment: lifts, etc.; detection and analysis equipment: detection lines, exhaust gas analyzers, decoders, lighting instruments, oscilloscopes, refrigerant filling instruments, smoke meters, endoscopes, etc.

3. Multimeter Multimeter is a multi-functional, multi-range and easy-to-carry electronic instrument. It can measure a variety of electrical parameters such as AC and DC current, voltage and resistance. The multimeter used should meet the safety level of CATIII.

4. Automobile maintenance equipment can generally be divided into: automobile diagnostic equipment, detection and analysis equipment, maintenance and cleaning equipment, sheet metal baking and painting equipment, maintenance supplies, maintenance tools, tire equipment, machinery and equipment, etc. Due to the variety of types and varieties of automobile maintenance equipment, it is difficult to strictly classify, but the above This is the mainstream classification method in the automobile industry.

Which detector can read the fault code without starting the engine

If you are talking about a fault detector, you need to start the engine to detect the engine dynamic data.

Fault phenomenon: Turn on the ignition switch, turn on the ignition switch to the starting position, and the engine cannot start.

Can the automobile fault detector be connected to the computer: the working principle is to manually read the fault code and clear the fault code. The appearance is small and portable, simple to operate, and cost-effective. Suitable for friends or drivers, dedicated to special vehicles and accurate.

It means that the fault indicator light line is faulty and should be checked and repaired.

Engine fault detector

Car fault diagnostic instrument is a very important tool in car maintenance, which can effectively discharge the cause of car faults. The main functions include: reading fault code, clearing fault code, reading engine dynamic data flow, oscilloscope function, component action test, matching, setting and coding, English-Chinese dictionary, calculator and other auxiliary functions.

CarsHow to use the obstacle diagnosis instrument? Open the on-board OBD interface, insert the car fault diagnosis instrument into the on-board OBD interface, and connect the relevant accessories according to the instructions. Turn on the power supply, start the car fault diagnosis instrument, enter the operation interface of the car diagnosis instrument, and select the car diagnosis module.

Take the QFC4 engine comprehensive tester as an example to explain how to use the abnormal sound diagnostic instrument. The instrument consists of a host, a monitor and various auxiliary equipment. Connect the self-calibration tester to the engine. When the vehicle is grounded to the positive pole, the top of the contact rod of the abnormal sound sensor should be covered with an insulated magnet, otherwise the engine will turn off.

But the detection steps are generally connected. Open the chassis, take out the fault diagnostic instrument, and insert it into the decoder. Check the test main line and the 16-pin test line. Will test the masterThe wire is connected to one end of the diagnostic instrument, and the other end is connected to the 16-pin test wire. The other end of the 16-pin test cable is inserted into the communication socket in the lower left corner of the dashboard of the car.

How to use the car detector?

The method of using the car detector is: open the on-board OBD interface and insert the car diagnostic instrument into the on-board OBD interface; enter the operation interface of the car diagnostic instrument, detect and diagnose each system or detect the fault of the whole car; display the detection and diagnosis results on the operation interface.

How to use the car diagnostic instrument to turn on (1) Select the corresponding test card, assume that it is an A01 card, and insert its label upwards into the test card at the bottom of the host. ( 2) Connect the test main line to the host, the power cord at the other end is connected to the car cigarette lighter or the battery through a double clamp wire to energate the host.

The use of the car fault diagnosis instrument is very simple. First, connect the device, and then enter the fault inspection system and select the corresponding function for diagnosis. Next, let's take a look with the editor.

The first step to using a car maintenance computer detector is to connect it to the diagnostic interface of the car, which is usually located under the dashboard near the driver's seat of the vehicle. After starting the car, turn on the power of the detector, and then select the corresponding car brand and model according to the operation prompts on the instrument.
