Engine failure diagnosis and exclusion assessment platform

The device is composed of two parts: electronically controlled gasoline engine assembly and fixed table frames and running detection control panel frames.

The engine can perform the practice of normal operating conditions such as starting, acceleration, and deceleration, and truly display the structure and work process of electronic control gasoline engines.

Applicable to the teaching needs of automotive engines and m--ntenance tr--ning for middle and higher vocational and technical colleges, ordinary education colleges and tr--ning institutions.

 

two. Features

1. The real -operated electronic control gasoline engine fully shows the structure and working process of the electronic control gasoline engine. The engine can perform practical operations such as starting, accelerating, and deceleration.

2. The tr--ning table consists of two parts: the engine assembly and the fixed table frame and the operation of the operation detection control panel.

3. The tr--ning table panel is p--nted with color UV tablet inkjet circuit diagrams. Students can intuitively control the circuit diagram and the actual engine of the engine, and understand and analyze the working principle of the control system; The ** aluminum -plastic board is sprayed with a primer p--nt on the surface; the panel prints the color system circuit diagram that will never fade.

4. The tr--ning terminal is installed on the panel, and the electrical signals that can detect each sensor, actuator, and engine control unit pipe foot can be detected directly on the panel, such as resistors, voltage, current, frequency signals, etc.

5. The device detection panel is equipped with a 20cm steel table on the front base in front, which is convenient for placing data and detecting instruments.

6. The tr--ning countertop is installed with car instrument, fuel pressure gauge, and vacuum pressure gauge, which can display changes in the engine speed in real time;

7. There is a diagnostic seat installation of the tr--ning desk, which can be connected to a dedicated or universal car decoder to read the engine electrical control system to read the fault code, clear the fault code, and the data flow.

8. The tr--ning desk is equipped with a total power switch and protection device.

9. The base of the tr--ning platform is welded with steel structure, and the circular hand rod is welded on the front/sides of the front/sides. The surface is treated with a spraying process, with a self -locking wheel device. It is flexible, safe, reliable, and durable.

10. Machinery assembly and fitter assembly virtual simulation software: This software is developed based on Unity3D. It can choose 6 -level image quality. It has the design and virtual disassembly of the reducer and shaft structure, the design and simulation of common mechanical institutions, institutional resource libraries, institutional resource libraries. Typical mechanical institutions (virtual disassembly of gasoline engines), software is an overall software, which cannot be separate resources.

A. Turbine design and virtual disassembly interface can be selected from turbine sn--l pole cone gear reducer, second -level pilot gear reducer, conical cylindrical gear reducer, coaxial cylindrical gear reducer, cone gear reducer, first -class cylindrical, first -class cylindrical, Gear reducer.

The turbine sn--l tapered gear reducer: automatically play the assembly content after entering the software. Each step in the video has text description

Second -level unfolding cylindrical gear reducer: After entering the software, use the video to play content in the form of video. The video content should include: the name of the parts (scanning the QR code can see the part of the parts), the disassembly presentation (including disassembly, assembly), virtual disassembly Installation (including overall, low -speed shaft, mid -speed axis, high -speed shaft, box cover, box seat)

1. Experimental purpose:

Anaerobic digestion can be used to deal with organic sludge and high -concentration of dissolved organic industrial sewage (such as alcohol factories, food processing plants sewage), which is one of the m--n methods for sewage and sludge treatment.

In the process of anaerobic and digestion, it is affected by factors such as pH, alkali, temperature, and load rate. The amount of gas production is related to the types of operating conditions and types of pollution. Before the design of the digestive pool, it is generally necessary to determine the design parameters through laboratory trials. Therefore, it is important to master anaerobic digestive experiments.

Through the hope of this experiment, the following goals are achieved:

1 mastering anaerobic and digestive experiments;
