Application

This unit of competency defines the skills and knowledge required to assess induction, exhaust and emission control system operation and repair or replace faulty components.

It applies to induction and exhaust systems on mobile and stationary plant and equipment.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

What You'll Learn

Assessment Requirements

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria on at least two (2) occasions and include:

following work instructions, standard operating procedures (SOPs) and safe work practices

identifying and interpreting specifications, charts, lists, drawings and service documents to maintain induction and exhaust systems

checking induction and exhaust system for correct operation

checking emission control system performance for correct operation against specifications

using test instruments and equipment to isolate faults down to component level and visually and dimensionally checking components for wear against specifications

undertaking calculations and numerical operations to maintain induction and exhaust systems

removing and refitting components to engines, including using replacement parts from manufacturers’ catalogues

checking induction/exhaust system for leaks

using appropriate tools, equipment and techniques for each task

recording all test and repair activities in accordance with procedures.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

safe work practices and procedures and use of personal protective equipment (PPE)

principles and terminology of supercharging, filtering, inter and after cooling

performance and operational specifications of the induction and exhaust system

procedures and safety precautions for testing induction/exhaust systems for correct operation

equipment and procedures necessary to test flows, pressures and temperatures associated with induction/exhaust systems

components and applications of supercharging apparatus

maintain induction, exhaust and emission control systems

types of emissions, their relationship to standards and specifications and their effects on the environment

sources of emissions from mobile and stationary plant and equipment

exhaust gas recirculation (EGR) systems

supplementary catalytic reduction (SCR) systems

role of particulate filters, charcoal canisters, fuel evaporative control systems and crankcase ventilation in controlling emissions

supercharging apparatus such as turbo charging equipment

common faults associated with induction/exhaust systems and causes of those faults

appropriate action and procedures for correcting common faults in induction/exhaust systems

component specifications/tolerances and actions to be taken if the components are outside of specification

action to be taken if the components are ‘just’ within specification

measuring instruments to be used to carry out dimensional checks on components

the operation of the apparatus installed to balance fuel injection to boost pressure and control devices installed to prevent excessive turbocharger RPM and/or boost pressure

procedures and safety precautions for removing/fitting components to engines

procedures for recording test and repair activities undertaken on induction/exhaust systems

consequences of air/exhaust leaks on the safe operation of the induction/exhaust system and procedures for testing for leaks in induction/exhaust systems.

Assessment Conditions

Assessors must:

have vocational competency in maintaining induction/ exhaust systems at least to the level being assessed with relevant industry knowledge and experience

satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires

Where possible assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
