Petrol Engine Ignition & Injection System Trainer (EFU107) features a type of engine management which combines the control of both injection and ignition systems of the petrol engine operated by the motronic technology. The trainer features components of a real petrol engine vehicle and it is capable of simulating 20 common faults of petrol engine management system.
- Unit design allows the trainee to observe all system components clearly (both injection & ignition systems).
- Unit operation module includes ON/OFF switch to operate the system in addition to emergency switch to disconnect the system in case of any emergency during the training.
- The unit’s vertical panel includes all components required for applying motronic control such as electric circuitry, electronic control unit (ECU), fuel reservoir (tank), fuel pump, 4 injectors on a rail, 4 spark plugs, throttle valve, electric fan, and an electric motor, and various sensors.
- The unit includes an electric motor works to simulate the movement coming from the car engine.
- The motor drives a shaft that is connected to another shaft by gears; the first shaft represents the crank shaft while the second represents the cam shaft, where sensors measure the physically simulated crank shaft angle and speed and feeds them back to the ECU.
- The above arrangement is surrounded by protective shield made of acrylic to ensure safety during the training.
- The electric fan is installed with an air mass sensor to feedback a simulated signal to the ECU as if air passes through an engine’s throttle valve.
- The trainer includes an ignition switch to start system , in addition accelerator pedal is used to increase & decrease speed .
- A setup of four real injectors & four cylinders (simulated using 4 graduated glass tubes) is mounted on the front panel in order to provide a better observation experience of the fuel injection process.
- Additionally, system spark plugs are mounted behind a transparent protective covering and so the ignited sparks can be noticed easily.
- The unit is capable of simulating 20 different faults of the system via faults switches on the vertical panel.
- A schematic diagram of the system operation and components is printed on the unit’s vertical panel for guidance during operation.
- Measuring points at system components terminals on the schematic diagram allows connecting an external multi-meter or oscilloscope between these terminals to measure the output value or signal before and after activating the faults, in addition to the ability of connecting an external fault diagnosis equipment.
- The trainer is mounted on a robust frame that can be easily relocated.
