PURPOSE OF THE UNIT STANDARD 
Learners accredited with this standard will have knowledge of integrated fuel injection and ignition systems including diesel injection as used on modern vehicles and variants such as Single point injection/common rail systems. The standard involves the application of both the theory and skills to achieve these autotronics-specific outcomes. This is an important set of competencies for an individual embarking on the NQF Level 4/5 autotronics qualification. The unit standard is differentiated from other unit standards in that its primary focus is on testing and diagnosis of the electrical/electronic elements of these systems as applicable to the autotronics specialist. The learner completing this unit standard should also have an understanding of how mechanical aspects on the engine can affect the functioning of the ignition/fuel injection system.

Learners credited with this standard will be able to:
  • Differentiate between the main types of injection systems.
  • Use wiring and technical diagrams/information to obtain information on these systems.
  • Identify and explain the purpose/functions of common components for combined ignition and injection systems.
  • Explain the purpose/functions of sub-systems of combined fuel injection/ignition systems.
