Description
Employability Skills
Learning Outcomes and Application This unit describes the performance outcomes required to install compressed natural gas (CNG) fuel systems. It involves preparing for the task, selecting, installing, testing and adjusting the system for correct operation, and completing workplace processes and documentation.It applies to those working in the automotive service and repair industry. The CNG fuel systems include those of agricultural machinery, forklifts, heavy commercial vehicles, light vehicles or mobile plant machinery. Licensing, legislative, regulatory or certification requirements may apply to this unit in some jurisdictions. Users are advised to check with the relevant regulatory authority.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Assessors must satisfy NVR/AQTF assessor requirements.

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 CNG fuel systems that they have installed, e.g. repair orders.

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

AS/NZS 2739 Natural gas (NG) fuel systems for vehicle engines

manufacturer vehicle CNG system specifications

one vehicle requiring installation of a CNG fuel system

CNG installation kit, including:

fill valve and fill hose

fuel container and mounting

service line

vaporiser

regulator

safety lock-off devices

mixers or injectors

associated electrical and electronic system, including selector and safety switches

compliance plates

testing equipment for CNG fuel systems, including CNG fuel leak testing equipment, including exhaust gas analyser

tools, equipment and materials appropriate for installing CNG fuel systems.
