The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. |
Failure analysis and evaluation process | The objectives of the failure analysis and evaluation process may determine fault rectification measures, effect variation in system characteristics and parameters or enhancing system performance. |
Engine and fuel systems | Engine and fuel systems are to include two-stroke, four-stroke rotary, petrol engine to 8 litres and diesel engine to 8 litres. Engine and fuel systems to be covered in this unit are to include the engine and related fuel, ignition, intake, exhaust, lubrication and cooling systems. Systems are to include innovative engine design and ceramic engine componentry. |
Engine and fuel system failures | Engine and fuel system failures covered by this unit are to include engine (poor performance, excessive oil consumption, engine stoppages), fuel (contamination, flow, pressure, leakage), ignition (no-start, no-run, misfire, erratic operation, lack of power, charging), intake (leakage, noise, vibration, inadequate control, exhaust (pressure, abnormal emissions), lubrication (pressure, flow, leakage, abnormal engine wear, inadequate filtration, sludge formation, excessive deposits, overheating), cooling (overcooling, insufficient cooler flow, coolant out of specification, lack or air flow, internal corrosion), mounting (noise, vibration, hardness, clutch shudder, erratic transmission control). Engine and fuel system failures covered by this unit are to include indirect faults caused by the influence of external systems which may or may not be faulty in their primary operations. |
Unit context | WHS requirements include vehicle industry regulations, safety management systems, hazardous substances and dangerous goods code and safe operating procedures. Work is carried out in accordance with legislative obligations, Australian Design Rules, environmental legislation, health regulations, manual handling procedures and organisation insurance requirements. Work requires individuals to demonstrate research, analytical, judgement and problem-solving skills in the diagnosis of faults. |
Evaluative criteria | Evaluative criteria, sometimes referred to as success factors, detail the criteria against which the achievement of the objectives of the analysis judged. They are to include statistically based criteria and may include other measures. |
Isolation procedures | Equipment isolation procedures to industry and enterprise standards. |
Testing equipment | Testing equipment is to include bore gauges, compression gauges, computer-based diagnostic system (direct and internet), cooling system analyser, dial gauges, exhaust gas analysers, micrometers, multimeter, oscilloscope, pressure gauges, stethoscope, telescopic gauges, temperature gauges, tachometer, timing lights, vacuum gauges, verniers, and may include anemometer, barometer, hygrometer, specific gravity gauge. |
Tests | Tests are to include component wear analysis, compression, cylinder leakage, engine performance, exhaust gas sampling, flow, oil consumption, pressure, sample collection/processing, specific gravity, temperature and vacuum. |
Personal protective equipment | Personal protective equipment is to include that prescribed under legislation, regulations and enterprise policies and practices. |
Information and procedures | Workplace procedures relating to the use of tooling and equipment. Workplace procedures relating to reporting and communication. Manufacturer/component supplier specifications and application procedures for testing equipment and materials. Manufacturer/component supplier specifications, schematics and operational procedures related to light vehicle engine and fuel systems. Australian Design Rules. Vehicle industry regulations. Vehicle industry publications related to emerging steering and suspension system technology and technology changes. |
