1 Read the text and answer the questions.
The principle of the internal combustion engine has not changed in over 100 years. The engine takes in
fuel and air which is compressed in a combustion chamber. The mixture is then ignited by a spark plug
to produce an explosion, which moves the piston in the cylinder. The up and down motion of the piston
in the cylinder is converted into a rotational motion by the crankshaft. The rotational force generated by
the engine is known as torque.

Metal plate that is held by the calliper; it is covered with a heat-resistant material that rubs against
the disc to slow down its rotation.
3 Read the text and answer the questions.
Removing brake pads
Once the car is elevated and the tyre and wheel have been removed to expose the brake rotor and
calliper, you can begin to remove the brake pads. First you need to remove the calliper. Using your
spanner, loosen the bolts whilst holding the calliper in place, and then remove the bolts. Once those bolts
are removed, lift the calliper off the brake rotor. It will still be connected to the vehicle via the brake line.
DO NOT let the calliper hang by the brake line as this could cause damage to the brake line. Secure the
calliper to a nearby suspension component. Make sure that the brake line is slack and not pinched or
kinked. Turn the calliper over, and you can now see the brake pads. Remove the pins or bolts that hold
them in place and slide the pads out.

Air filter
Air is sucked into an engine when the pistons move down the cylinders, creating suction. If the air
contained dirt, insects or any other contaminants, it would be sucked straight into the engine, possibly
causing serious damage. The filter is used to prevent any dirt entering the engine. It is important the
air filter is renewed regularly, to stop it from becoming blocked, which would prevent air getting into
the engine.

The alternator
The alternator uses the principle of electromagnetism to produce current. There are two main
components that make up an alternator. They are the rotor and the stator. The rotor is connected
directly to the alternator pulley. The drive belt spins the pulley, which in turn spins the rotor. The stator
is mounted to the body of the alternator and remains stationary. There is just enough room in the centre
of the stator for the rotor to fit and be able to spin without making any contact.

chemicals. Routine handling of solvents, oil, fibreglass, coolants and other irritants with bare hands
can cause skin problems.
d Wear disposable earplugs when noise is loud due to engine, compressor and impact tool noises.

What system of an automobile or truck determines the vehicle’s cornering ability and ride stiffness?
a Steering system
b Braking system
c Electrical system
d Suspension system
2 The reason a particular quarter inch nut may not fit a particular quarter inch bolt is because …
a they may be of different thread classifications.
b a quarter inch bolt is incompatible with a quarter inch nut of the same size.
c the metal alloys from which the nut and bolt are made may cause the nut to “seize.”
d quarter-inch bolts require a nut of a slightly larger size to fit.
3 It would be better to use thick viscosity motor oil in …
a cold climates (makes vehicle start-ups easier).
b tropical climates (makes the engine heat build-up).

1 The diesel engine does not require a large
supply or a long warming-up period.
2 The diesel engine is highly efficient in
heat energy into work.
3 The diesel engine differs from the
engine in that the ignition of fuel is caused by
compression of
in its cylinders instead of by a spark.
4 The speed and
of the diesel are controlled by varying the amount of fuel injected into
the
