Release 1 

New unit of competency.

Application

This unit describes the performance outcomes required to analyse and repair performance fuel injection systems and associated components. It involves identifying, evaluating, selecting, justifying and documenting the most appropriate rectification method or variation to the rectification method. It also involves developing and modifying performance improvement strategies in fuel injection systems and associated components. The unit includes the analysis of multi-system and intermittent faults which may be caused by operating in adverse conditions.

It applies to those working in the motor sport industry.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.

Assessment must include direct observation of tasks.

Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the performance fuel injection systems they have analysed and repaired, e.g. work order.

Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.

The following resources must be made available:

  • automotive repair workplace or simulated workplace
  • workplace instructions
  • manufacturer specifications for vehicle performance fuel injection systems
  • three different competition vehicles with faults in their performance fuel injection systems
  • diagnostic equipment for performance fuel injection systems, including:
