Top 10 common car
parts and their use

Now if you are like me and the only thing you know about cars is that it needs
petrol and oil to run, then this article is for you. We go through the top 10
common car parts and what they actually do in easy to understand explanations.
Car engine, the big metal box type thing
under the bonnet in human biology terms
is the heart of the car and like the heart
the engine is made up of all different
components which make the car move
and function. Fuel and air is fed into the
engines cylinders where combustion takes
place, causing rapid expansion of the
gases in the form of heat which then
Ever wondered how all your car electrics
work? This is the job of your car’s
alternator – it turns the rotating movement
of the drive belt into electricity. It does this
by turning a magnet inside a coil of wire
producing a voltage to charge the car’s
battery. This allows the battery to power
for the cars electrical components like your
headlights, brake lights and internal
Your car’s brakes are made up of different components and the brake pads job
is to slow the rotation of the wheels by sandwiching the brake discs, causing
friction and heat.
Your car’s engine can get very hot from all
the moving parts within it, the radiator is
located at the front of the car allowing
fresh air to run over and through the
radiators fins to help absorb the coolants
excess heat to ensure the car doesn’t over
heat. Coolant is pumped through the
radiator and through chambers in the
engine block by the engines water pump.
The car’s suspension job is to keep your tyres in contact with the road and
works to reduce the impact felt in the cabin on varying road surfaces, so if your
car is bouncing a lot it may be time to get your suspension looked at.
The muffler is a metal container under the car which has a series of sub-
chambers inside, which help to reduce the engine noise. Ever wonder why
some cars are so loud when they drive past? It’s generally because the muffler
has been altered.
The chassis is where all the parts of the car are bolted on and protected.
Your car’s ignition acts like a match that ignites the air/fuel mixtures which
makes the car run.
The exhaust pipe carries the engines exhausted combustion gases into a special
gas converter (or in mechanic speak a catalytic converter) and from there to the
muffler and eventually out the back of the car as emissions.
The car’s transmission job is to transmit the power and torque from the engine
to the wheels in different gear ratios according to the car’s road speed.
