Fuel Atomization

Fuel Atomization

 

in internal-combustion engines, the mixing of fuel with air or some other oxidizer within the engine in order to achieve complete and rapid combustion of the fuel. In carburetor engines atomization is accomplished by the carburetor; in diesel engines and gasoline engines with direct fuel injection atomization is accomplished by nozzles. In all piston engines atomization also occurs while the fuel mixture moves through the combustion chamber. In gas turbine and jet engines atomization is ensured by the appropriate location of apertures in the air intake pipes, by the frontal arrangement of the combustion chambers, which causes turbulent air to enter the combustion zone of the chamber, and by the use of nozzles.
