Elements and Performance Criteria

Work includes the use of dynamometers to test engine performance and the interpretation of dynamometer results in order to maximise engine performance for the motorsport/performance enhancement environment. This includes dynamometer set up, testing, use of software relevant to the dynamometer, data logging and analysis and dynamometer shutdown procedures
Dynamometers include engine and chassis dynamometers. Dynamometers may include water or electrically loaded dynamometers
Units of measurement must include metric and imperial units

OH&S requirements include State/Territory and Commonwealth legislation, material safety management systems, controlling body requirements, manufacturer specifications and local safe operating procedures
Work is carried out in accordance with legislative obligations (including environmental requirements), health regulations, manual handling procedures and team insurance requirements
Work requires individuals to demonstrate discretion, judgement and problem-solving skills in the set-up and operation of machines
Competence may be demonstrated in workplaces involved in the design, development, manufacture and maintenance of performance vehicles and/or performance vehicle components and assemblies used in motorsport

Tooling and equipment include, but may not be limited to, engine dynamometer or chassis dynamometer, hand and power tooling, engine compression test kit, vacuum/pressure gauges, flow meters, exhaust analysers, engine diagnostic computer hardware and software

Personal protective equipment is to include that prescribed under dynamometer manufacturer/component supplier specifications, legislation, regulations and enterprise policies and practices

Controlling body rules, category rules and supplementary regulations
Team procedures relating to testing engines using a dynamometer
Task instructions including worksheets, checklists, plans, drawings and designs
Team procedures relating to reporting and communication
Team procedures relating to the use of tooling and equipment
Manufacturer/component supplier specifications and application procedures for test equipment and material
Australian Design Rules (where applicable)

Critical aspects of evidence
Interpret and apply team requirements, controlling body and category rules and supplementary regulations
Correctly apply and use safety equipment and personal protective equipment

Follow task instructions, operating procedures and inspection processes to:

minimise the risk of injury to self or others
prevent damage to competition vehicle or equipment
achieve required outcomes within team time and quality standards

Correctly set up and operate an engine dynamometer to test a minimum of two (2) engines to complete the following:

determine engine performance
analyse engine performance data
assess effect of engine and sub-system modifications and present to team members as information to complement engine/vehicle set-up
confirm effectiveness of engine and sub-system modifications
Work effectively with others
Modify activities to cater for variations in workplace context and environment

Underpinning knowledge
Engine performance and dynamometer terminology
Preparation procedure for dynamometer testing
Dynamometer operation and use of associated hardware and software
Test environment correction factors
Dynamometer data interpretation and analysis
Operator dynamometer maintenance
Procedures for reporting task completion
OH&S policies and procedures

Specific key competencies, underpinning and employability skills required to achieve the performance criteria
These include a number of processes that are learned throughout work and life, which are required in most jobs. Some of these are covered by the national key competencies, although others may be added. The details below highlight how these competencies are to be applied in the attainment of this unit.

Application of the key competencies in this unit are to satisfy the nominated level in which:

Level 1 - relates to working effectively within set conditions and processes;
Level 2 - relates to the management or facilitation of conditions or processes; and
Level 3 - relates to the design, development and evaluation of conditions or process.
How will the candidate apply the following key competency in this unit? The candidate will need to:

Collect, analyse and organise information
Collect, organise, understand and analyse information related to dynamometer test results, team requirements and safety procedures
(Level 2)

Communicate ideas and information
Communicate ideas and information to enable confirmation of work requirements, coordination of work with technical supervisors, other technicians and team members and the reporting of work outcomes and problems
(Level 2)

Plan and organise activities
Plan and organise activities including the preparation and layout of the work area and the obtaining of equipment and material to avoid backtracking, workflow interruptions or wastage
(Level 2)

Work with others and in a team
Work with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity
(Level 2)

Use mathematical ideas and techniques
Use mathematical ideas and techniques to correctly complete measurement of engine performance required for the team
(Level 2)

Solve problems
Use dynamometer testing to solve problems with engine performance
(Level 2)

Use technology
Use workplace technology related to dynamometers including tooling, equipment, calculators and measuring devices
(Level 2)

Resource implications
Access to tooling and equipment as identified in the Range Statement including engines, dynamometer and test equipment and technical references or information

Method of assessment
Assessment methods must confirm consistency of performance over time and in a range of workplace contexts
Assessment should be by direct observation of tasks and questioning on underpinning knowledge
Assessment should be conducted over time and may be in conjunction with assessment of other units of competence

Context of assessment
Assessment may occur on the job or in a workplace simulated facility with process equipment, material, work instructions and deadlines
