Maintain induction/exhaust systems
Assessment tool
Version 1.0
Issue Date: May 2024
Testing procedures would typically require the person to understand 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. Typical faults would be associated with excessive air inlet restrictions, excessive exhaust back pressures, too much/little boost pressure, ineffective inter/after cooling, etc.
Band: A
Unit Weight: 4
This unit covers assessing induction/exhaust system operation and repairing or replacing faulty components.

Evidence Required
List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
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 | A person who demonstrates competency in this unit must be able to maintain and rectify induction/exhaust systems. Competency in this unit cannot be claimed until all prerequisites have been satisfied. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts. |
Context of and specific resources for assessment | This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate. This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with maintaining and rectifying induction/exhaust systems, or other units requiring the exercise of the skills and knowledge covered by this unit. |
Method of assessment | Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials. |

Assessment Tasks
Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
Required skills |
Look for evidence that confirms skills in: reading, interpreting and following information on written job instructions, specifications, standard operating procedures, charts, lists, drawings and other applicable reference documents planning and sequencing operations checking task-related information checking for conformance to specification identifying a variety of applications of supercharging, filtering inter and after cooling checking the induction/exhaust system for correct operation in accordance with standard operating procedures determining the flows, pressures and temperatures of the given induction/exhaust system using appropriate techniques and equipment isolating faulty component in accordance with standard operating procedures using all test instruments and equipment visually and dimensionally checking component parts for wear using supplier catalogues to select component parts removing components and fitting to engines recording all test and, where appropriate, repair activities checking the induction/exhaust system for leaks undertaking calculations and numerical operations within the scope of this unit |
Required knowledge |
Look for evidence that confirms knowledge of: the principles and terminology of supercharging, filtering, inter and after cooling the performance and operational specifications of the induction/exhaust system the procedures and safety precautions for testing induction/exhaust systems for correct operation the equipment and procedures necessary to test flows, pressures and temperatures associated with induction/exhaust systems the procedures for recording flows, pressures and temperatures common faults associated with induction/exhaust systems and causes of those faults the appropriate action and procedures for correcting common faults in induction/exhaust systems the component specifications/tolerances and actions to be taken if the components are outside of specification the action to be taken if the components are 'just' within specification the measuring instruments to be used to carry out dimensional checks on components the procedures and safety precautions for removing/fitting components to engines the procedures for recording test and repair activities undertaken on induction/exhaust systems the consequences of air/exhaust leaks on the safe operation of the induction/exhaust system and procedures for testing for leaks in induction/exhaust systems hazards and control measures associate with maintaining and rectifying induction/exhaust systems, including housekeeping safe work practices and procedures |
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. | |
Supercharging | Supercharging apparatus includes turbo charging equipment |
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
