Electrical Tools

Tool/Equipment	Appropriate Use	Auto Specific?
Electric Drill	Used to produce rotational force for drilling holes when using a drill bit, or screwing when using a screw bit. It is electrically powered so the user needs to be aware of where the trailing cable is so that it is not damaged and electrocution occurs.	No
Electric Grinder	Uses abrasive discs to remove material in a wasting form from an object. Typically used for cutting through metal. Can also be used to smooth down any sharp edges or burrs.	No
Electric Sander	Used to sand surfaces using abrasive pads, making the surface smooth. Typically used in preparing a surface prior to paint spraying.	No

Spanners

Tool/Equipment Image Appropriate Use Auto Specific? Torque Wrench Tightening nuts and bolts to a specific torque. In some situations, for example, attaching wheels, the fastenings need to be tightened to a specific torque so they are not too loose or become damaged by being over tightened. No Box Spanners General use of tightening nuts and bolts. Each end is a different size to reduce the total number of spanners required to cover a range of bolt sizes. The ends generally have 6 or 12 points to provide ease of use on hexagonal shape bolt heads. No Allen Spanners (Hex Keys) To drive in bolts or screws with hexagonal sockets. They have the advantage of providing 6 contact surfaces during use. No Ratchet Box Spanner Similar to a box spanner but more suitable in situations where rotational space is limited. The ratchet allows the spanner to be returned to its original position without the need for removing it from the fastening. Torque is applied in one direction, and free movement a...

Distributorless Ignition Systems

Investigation – Investigating Distributorless Ignition Systems Distributorless ignition systems (DIS) are used to ensure the air and fuel mixture in an engine is ignited at exactly the right time for efficient combustion to occur. They comprise mechanical and electrical components that, together, provide appropriate timing of the spark at each spark plug. Use the information in the related presentation to identify the components and voltage waveforms of DIS. Distributorless Ignition Systems a) Identify the components of this distributorless ignition system. A - ECU B - Crankshaft position sensor C - Ignition control module D - Coil pack E - Spark plug wires F - Spark plugs b) Draw a diagram to show the relationship between the primary voltage waveform and the secondary voltage waveform for one ignition coil. Ensure the diagram shows the waveforms for 2 spark plugs. A typical early DIS system will comprise which of these components? Select all the correct answers. Ignition control...

Miscellaneous Workshop Equipment

Miscellaneous Workshop Equipment Tool/Equipment Image Appropriate Use Auto Specific? On-vehicle Brake Lathe Used for skimming brake discs to remove imperfections or damage from brake pads. Saves removing the discs from the vehicle. Yes Bench Brake Lathe A lathe designed specifically for finishing brake drums and brake discs. Yes Parts Cleaning Tank Used for cleaning the inner and outer surfaces of parts prior to installation in a vehicle. Many parts may be reused on a vehicle if they are cleaned of dirt and debris. No Hydraulic Press The hydraulic press uses hydraulic pressure to apply a force to parts. They can be used in a forming process or for splitting components, for example, removing a bearing. Even a small press can produce several tonnes of force. The example shown produces 10 tonnes of force. No
