Intake and exhaust electronic controlled educational unit (EIG105) features a real automotive exhaust system with its complete range of components wired and connected and ready for operation. The system is designed to demonstrate the operation & characteristics of intake and exhaust system found in real vehicles. The unit is provided with a touch screen PC equipped with BEDO troubleshooting software used for simulating most common faults of intake and exhaust system , that helps enhancing maintenence and troubleshooting skills of the same system.
- This unit features an electronic controlled simulation of intake & exhaust system at the upper part of the system front panel.
- The system including two schematic diagrams, one of them is the electric circuit of intake and exhaust while the other is the ignition switch electric circuit.
- This diagrams are supplied with LEDs to show the sequence of the intake and exhaust processes.
- The middle part of the front panel includes a real intake & exhaust system divided into four sections:
- Mechanical simulation components
- Inputs
- Outputs
- Feedback components, in addition to the indicators panel.
- The lower part of the unit includes the fault switches, the operation panel, and the touch screen PC.
- Mechanical simulation components are:
- Exhaust manifold
- Intake manifold
- Throttle body
- Mass airflow sensor
- Air filter
- Measuring terminals.
- Mass airflow sensor has three modes for different three types of intake & exhaust systems for further experiments.
- Inputs components are:
- Water temperature sensor WTS,
- Oxygen sensor,
- Environmental temperature control switch
- Throttle body 1
- Throttle body 2
- Throttle body control switch
- Measuring terminals.
- Throttle body as the airflow sensor has three modes for different three types of intake & exhaust systems for further experiments.
- Output components are:
- Purge control solenoid valve (PCSV
- Canister, throttle body
- Exhaust gas recirculation (EGR) Solenoid.
- Feedback components are crank gear and crank position sensor.
- The indicators panel includes:
- Digital displays of the intake & exhaust system Inputs (mass airflow sensor)(three modes) as voltages and mass flow rates
- Air temperature sensor (as voltage and temperature),
- Water temperature sensor (as voltage and temperature)
- Oxygen sensor (as voltage)
- Outputs PCSV (as opening percentage, in addition of operation indication LEDs)
- EGR (as opening percentage, in addition of operation indication LEDs)
- Feedback (throttle position sensor (as voltage and degree of opening)
- RPM digital display.
- Operation panel of the trainer contains:
- ignition switch
- emergency switch
- operation ON / OFF switch
- Switch to select the mode of the throttle
- Switch to select the mode of the mass airflow sensor.
- The unit is also provided with seven fault switches to simulate most common faults of the intake & exhaust system.
- System is equipped with measuring test points 4 mm to perform connection, measurement and testing processes.
- Each component has its labeled name with its terminals.
- The labeled names of the components and the schematic diagrams are printed on the front panel using the ultraviolet technology.
- The signals are demonstrated during operating any of the sensors of the trainer.
