The system comprises all the elements that control the air-fuel ratio, the injectors, the ECU, and all the sensors associated with the control system. 

This real component trainer provides the instructor with a working HDI common rail fuel injection system for group or whole-class demonstration.

This includes all the individual components of the system presented on a moveable, steel-frame panel with each component clearly identified.

Variation of the engine speed allows the measurement of parameters within the system that are speed dependent. 

The system also includes a range of switchable faults for diagnostics training.

This is a dry-running system that uses electronic indicators to demonstrate injector operation.

This is achieved by changing the rotational speed of the electric motor that drives the unit.
