This system covers engine operation, engine performance and emission controls. The panel contains exercises with the computer-controlled inputs and outputs. It also provides dynamic demonstration of engine torque and horsepower ratios. The effects of individual engine sensors and engine controls on engine performance and emissions can be demonstrated under different operating conditions. Ambient temperature and altitude controls are provided to show environmental effects on engine operation and performance. The instructor can insert malfunctions, simulating customer complaints and problems that occur daily in the work area.

The instructor can insert malfunctions in electrical or mechanical components. Experiments and troubleshooting exercises develop the necessary problem-solving skills and diagnostic procedures for automotive technicians today.
These exercises include:
- Operation and function of major computer output actuators
|
- Detection and repair of exhaust gas recirculation valve when stuck
closed and open
|
- Operation and function of major input sensors
|
- Detection and repair of worn and leaking rings
|
- Detection and repair of shorted and/or open sensors: coolant
temperature, air charge temperature, manifold absolute pressure,
throttle position, air preheat solenoid, idle air control, and
exhaust gas oxygen
|
- Detection and repair of air control bypass valve when stuck
in bypass and in conventional position
|
- Detection and repair of clogged fuel injector and low pressure
fuel pressure regulator
|
- Detection and repair of improperly seated valves
