Elements and Performance Criteria

Range Statement

Specifies different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Range is restricted to essential operating conditions and any other variables essential to the work environment.
Diagnostic information includes one or more of the following:	engine efficiency fuel consumption temperature

Common combustion faults include one or more of the following:	engine cylinder fuel supply lack of total combustion

Methods of pressure-charging diesel engines include one or more of the following:	exhaust gas turbo charging positive displacement engine-driven blowers under-piston assistance

Diesel engine components include one or more of the following:	bedplates camshafts crankshafts cross-heads cylinder heads exhaust valves frames fuel injectors fuel pumps liners pistons tie-rods for two- or four-stroke engines turbochargers valves and rocket gear

Hazards include one or more of the following:	acids chemicals defective or bypassed machinery protective devices defective or inappropriately adjusted exhaust systems enclosed spaces flammable liquids under pressure hydrocarbons lifting heavy components both unaided and with lifting gear leaking oil and fuel

Causes include one or more of the following:	airlock in feed water system cleanliness of economiser tubes failure of economiser feed pump loss of feed-water supply
