SOME DEFINITIONS
Atomisation:
Why is it necessary to atomize fuel?
The breakup of fuel into minute spray particles so as to ensure an intimate
mixing of air and fuel is known as atomization. Even though fuel oil is
classified as a flammable liquid, most fuels will not burn easily in a liquid
state. If you were to drop a lit match in a container of fuel oil, it would
PROBABLY go out almost immediately (don’t try this!). In order for fuel oil to
burn, it must first be transformed from a liquid to a vaporized state ~
atomized. Atomization increases the exposure of the fuel to the oxygen in
the air; this promotes combustion.
Turbulence:
A swirling effect of air charge in the
cylinder which in combination with
atomized fuel spray gives intimate mixing
and good overall combustion. Combustion
chambers ( liners , pistons etc.) are
designed to optimize air turbulence when
they enter the combustion chamber.
