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.
