Describe:
What is a piston and what does it do?
A piston is a key component in a reciprocating engine. It's made
from a cylindrical piece of metal with piston rings that help to
form an air-tight seal once the piston is installed within the
engine cylinder. The piston is attached via a piston pin or gudgeon
to a connecting rod, which in turn is connected to the crankshaft.
In four-stroke (petrol and diesel) car engines, the intake,
compression, combustion and exhaust process takes place above the
piston in the cylinder head, which forces the piston to move up and
down (or in and out in a horizontally opposed - or flat - engine)
within the cylinder, which causes the crankshaft to turn.
Why a piston is made of aluminium
Engine components need to be hardwearing for longevity and
lightweight to improve efficiency.
As a result, pistons are usually made from an aluminium alloy,
which is the best all-round material to use in the average car and
motorcycle engine. However, the piston rings (usually comprising,
from top to bottom, a compression ring, a wiper ring and an oil
ring) are made from cast iron or steel.
How piston rings work
The oil ring wipes oil from the cylinder wall when the piston is
moving, but over time it and the other rings can wear, allowing oil
from the crankcase to move into the combustion chamber.
Excessive oil consumption and white smoke from the exhaust
tailpipes indicate piston ring wear.
Internal combustion engines can operate with a single cylinder –
and therefore one piston (for example, most motorbikes and petrol
lawnmowers or generators) or as many as 12 (high-performance sports
cars), but most cars have four or six cylinders.
Radial engines, commonly used in propeller-driven planes, have an
odd number of cylinders and pistons for a smoother operation.
Pistons also feature in external combustion engines, otherwise
known as steam engines, where water is heated in a boiler and the
resulting steam is used to propel a pair of pistons (typically) in
external cylinders, which then drive the wheels. Rotary engines do
not have cylinders or pistons.
