I. About the product
The device adopts the real components of BOSCH common rail electronically-controlled diesel engine electronic fuel
injection system to illustrate engine fuel injection system's structure and working process. The device applies to
engine fuel injection system and maintenance training courses of secondary and senior vocational schools, ordinary
education and training institutions.
ii. Features
1. Real and operable common rail diesel engine fuel injection system to illustrate the structure and working process.
Rolling crankshaft position signal wheel, common rail diesel sequential simultaneous injection
2. The instruction board has color circuit and working principle diagrams, covered by a 3mm-thick organic glass
protector fixed with aluminum. Students can compare the diagram and actual items to learn and analyze the working
principle of the electronic fuel injection system.
3. Detection terminals are installed on the teaching board. On the platform, operators can detect resistance, voltage,
current, and signals of components of the electronic fuel injection system.
4. The instruction board is installed with diagnosis socket connecting dedicated or universal automobile decoder. The
diagnosis socket reads fault codes, clears fault codes, and reads data stream from the engine electronicallycontrolled
system.
5. The instruction board's base frame is made of steel and the surface is paint-coated. Self-retention wheels are
installed and a 40cm tabletop is fixed on the base frame to place materials and light testing devices.
6. Instead of using accumulators and requiring charging, the instruction board connects to a 220V AC voltage which
changes to a 12V DC voltage through the internal circuit,without battery, reduce the charging trouble,The 12V DC
voltage protects the instruction board against short circuit.
7. Intelligent fault-setting and appraisal system:
1) The system employs patented, stable and anti-virus digital integrated circuit board and the latest MCU technology
and associated fault setting control technology.
2) Independent test and appraisal can be performed without a computer. The teacher and student interfaces are
separated. Teachers enter the teacher interface to provide test paper and the students answer questions on the
ordinary interface. Teachers prepare the test: Select "Setting fault point and fault type" through the main functional
menu in the MML interactive interface. Enter the password to page for setting faults. Select the set faults from the
fault name list. You can select three fault types including "Open circuit fault", "Short circuit fault", and "Improper
contact". Students answer questions: Enter the main menu and select "Test for skills of finding faults". After finding
the fault through a test operation, students select the fault name or type. If the answer is correct, the system displays
that "Correct, the fault is removed"; If the answer is incorrect, the system indicates that "incorrect, please check
again". The number of attempts for each question can be set to 1-10 by the teacher. Test bank applicable to the
device is integrated. The test bank can be edited according to the requirements of users.
3) High resolution 3.8-inch 0.225 x 0.225 LED monitor, Chinese or English menu interface, friendly MML. 4 operation
keys make the operation simple and quick.
4) Set the line breaking, grounding short circuit and improper contact faults at any circuit. Set and control common
faults relevant to module pins. Users can adjust the number and type of fault setting points.
5) The RJ45 network interface is installed and the RS-232 port is provided. Use the fault setting devices of network
cable or other devices to form a network to control functions including fault setting, fault removal, parameter setting,
remote startup, information feedback, and appraisal through the main control computer.
