Fuel Injection Trainer - Multi Point Efi System.
The Four-Cylinder Engine trainer should consist of a complete, fully operational Multi Point EFI system. Original components should be utilized and clearly laid out on a display board that is mounted on an integrated floor stand, made from powder coated electro galvanized steel, mounted onto wheels for mobility. A color coded schematic chart, under a lexon polycarbonate protective screen, of the EFI system and circuit’s, should also be mounted onto the trainer for reference.
The engine sensors have a signal generator to simulate various engine conditions and a corresponding electrical meter that continuously monitors the signal. The effect of altering the sensor condition should be immediately apparent on the meters. The Electrical wiring diagram is provided in a special design panel to incorporate Input / Output connections from sensors and ECU. ECU should be open source and programmable and have the ability to connect to a PC, for programming and displaying system data.

2. Accessories: A set of 4mm terminals.
3. Included Accessories:
A. Electronic Fault Insertion System:
a. Multiple electronic fault insertion system: This system should allow for 10 faults to be inserted at any one time. Faults can be inserted individually or in groups.
b. Electrical Circuit Diagram Panel with Test Points: Features electrical circuit diagram panel that incorporates electrical test points that allow the student to take measurements during the troubleshooting exercises.
c. Electronic Fault Insertion System with LED Display: This should be incorporated into the electrical Circuit Diagram panel. The system should be able to activate the fault via pushbuttons that in turn operate electrical relays that cause the fault to occur. When the fault is electronically activated a corresponding LED will illuminate showing the fault is active.
d. Student Testing Mode: The LED fault indication display can be deactivated, so that the faults can be active but the display is switched off.
e. Electronic Fault Reset Button: The LED control should have a fault-reset button that will clear and reset the system back to normal.
The trainer should come complete with a training course on the EFI fuel injection system operation and servicing including student job sheets and a technician manual.
