A4 lever arch folderThis is a hard covered folder for holding any course notes you may write up, and for any diagrams you may draw.

It is important to get into the habit of writing up your notes on a regular basis. To that end, you are supplied, on repayment, with a spiral notebook and black and red pens.

You can see the most current prices of this and all the other items issued on repayment here...

:

A4 refill padsDuring your phase 2 training, it is important that you take and write good notes on the course material. You should also get used to drawing detailed diagrams of vehicle and machine components.

In order to help you do this, you will be issued with, on repayment, a spiral notebook and an A4 refill pad. If you fill these pads and notebooks, the stationery charge you pay during induction will cover you for the issue of additional refill pads and spiral notebooks.

Advanced Automotive Engineer.

This is a qualification awarded by the Institute of the Motor Industry.

Anti blockier system, or anti-lock braking system, an electronically controlled system that senses the relative speeds of road wheels in order to determine whether braking wheels have locked up and began to skid. If they have, the system overrides the braking effort supplied by the driver, and frees the brakes until the wheel begins to turn again (stop skidding).

The system is informed by speed sensors at the wheels. These same sensors can be used to feed into a traction control system.

Acceleration is a change in speed. This change can be positive (speeding up) or negative (slowing down).

Acceleration is measured in m/s (metres per second).

Acid-proof apronDuring Phase 2, you will spend a lot of time working with lead-acid batteries. In order to protect your body and clothing from acid, you will be issued with an acid-proof apron.

You will also be issued with acid-proof gloves to protect your hands against acid.

You should wear the gloves, apron and your safety goggles whenever you work with lead-acid batteries.

Ackermann angle

Imaginary lines drawn through the king pin and the track control rod end on each side of a vehicle will intersect at a point just in front of the rear axle of that vehicle. The angle they make with each other is known as the Ackermann angle.

The purpose of the angle is to allow the front wheels to turn through different angles when cornering. This is because the inside wheel always needs to turn through a bigger angle in order to get around the corner without scrubbing.

Pressure sensors - active sensorsUnlike a passive sensor, an active sensor needs a power supply. There are 3 terminals on a pressure sensor. One is a supply, one is ground, and the third sends a signal back to the ECM.

Here, we can see the example of a pressure sensor. There are 3 terminals. We know this is an active sensor because it has these 3 terminals.

  1. Pin A is a 5 volt supply into the sensor.
  2. Pin B is common, meaning it is grounded to 0 volts.
  3. Pin C sends a signal back to the ECM. From this signal, the ECM calculates the pressure acting on the sensor.
