Elements and Performance Criteria

1. Prepare for dynamometer operation
   • Use team instructions, controlling body rules, category rules and component supplier specifications to specify job requirements, including design, quality, materials, equipment and specifications
   • Observe occupational health and safety (OHS) requirements, including regulatory requirements, equipment and system isolation requirements, extraction, fire hazard, fuel storage, scatter shields, noise regulations, environmental regulations and personal protection needs, throughout the work
   • Check dynamometer for calibration and serviceability and prepare for operation
   • Connect engine to dynamometer, including ancillary systems and monitoring/control systems
   • Connect exhaust extraction and check for serviceability
   • Prepare engine for dynamometer testing, including checking oil and water levels, and confirm engine tune and condition
2. Conduct dynamometer testing
   • Identify load and run sequence, including run-in period for new engines
   • Calculate correction factors and apply to results
   • Check engine connections to the dynamometer
   • Perform selected dynamometer testing sequence in accordance with technical specifications and directions and/or the locally authorised method
   • Analyse dynamometer test data and make valid conclusions about engine and sub-system condition and performance
   • Report findings, including recommendations for engine configuration and/or modifications to improve performance based on dynamometer data, to appropriate persons
   • Test approved modifications with confirmation runs
   • Present data to team members as information to complement engine/vehicle set-up
3. Clean up work area and log test results
   • Perform dynamometer shutdown procedure in accordance with manufacturer/component supplier requirements
   • Disconnect engine from dynamometer
   • Clean and refurbish dynamometer and associated tooling and equipment
   • Conduct operator maintenance of dynamometer
   • Log dynamometer test results to create/add to engine history

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Assessors must be satisfied that the candidate can competently and consistently 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 engines to complete the following determine engine performance analyse engine performance data assess effect of engine and subsystem modifications and present to team members as information to complement enginevehicle setup confirm effectiveness of engine and subsystem modifications work effectively with others modify activities to cater for variations in workplace context and environment
Context of and specific resources for assessment	The application of competency is to be assessed in the workplace or a simulated environment that reflects as far as possible the actual working environment Assessment is to occur using standard and authorised work practices safety requirements and environmental constraints Assessment is to comply with relevant regulatory requirements including specified Australian standards Where applicable reasonable adjustment must be made to work environments and training situations to accommodate ethnicity age gender demographics and disability The following resources should be made available access to tooling and equipment engines dynamometer and test equipment technical references or information
Method of assessment	Assessment must satisfy the endorsed Assessment Guidelines of this Training Package Assessment methods must confirm consistency and accuracy of performance over time and in a range of workplace relevant contexts together with application of Required Skills and Knowledge Assessment methods must be by direct observation of tasks and include questioning on Required Skills and Knowledge to ensure its correct interpretation and application Assessment may be applied under projectrelated conditions real or simulated and require evidence of process Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance but is able to be transferred to other circumstances Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role
Guidance information for assessment	Assessment processes and techniques must be culturally sensitive and appropriate to the language and literacy capacity of the candidate and the work being performed
