Application
This unit describes the performance outcomes required to test engines using a dynamometer. The engines being tested may be in a vehicle or stand alone. It involves preparing for the task, selecting the correct test procedure, carrying out testing, analysing test results, and completing workplace processes and documentation. It involves setting up and conducting dynamometer tests on engines, and logging, analysing and reporting the test data in order to maximise engine performance.
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.

Evidence of Performance
Before competency can be determined, individuals must demonstrate they can perform the following according to the standards defined in this unit’s elements, performance criteria, range of conditions and foundation skills:
carry out dynamometer testing on two different engines.
Evidence of Knowledge
Individuals must be able to demonstrate knowledge of:
work health and safety (WHS) and occupational health and safety (OHS) requirements relating to testing engines using a dynamometer, including procedures for:
connecting and securing engines to dynamometers
dealing with exhaust gases from engines
dealing with high levels of noise
environmental requirements, including procedures for trapping, storing and disposing of fluids released during engine testing
application, purpose and operation of engine dynamometers, including associated hardware and software
engine and chassis dynamometer testing procedures, including:
dynamometer preparation procedures
engine connection and securing procedures
vehicle connection and securing procedures
test environment correction factors
dynamometer data interpretation and analysis
operator dynamometer maintenance procedures
engine performance and dynamometer terminology.
Assessment Conditions
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 engines that they have tested using a dynamometer, 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
two different engines requiring testing using a dynamometer
engine or chassis dynamometer
tools and equipment appropriate for connecting, securing and disconnecting engines to dynamometers.
