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.

This could be explained by more intense combustion at 1000 bar injection pressure due to better fuel atomization and higher evaporation rates comparatively to results obtained at 800 bar [41].
Longer 5 V duty cycles allow longer ON times of the 38 V pulses, allowing for more fuel atomization. Smaller duty cycles allow shorter ON times of the 38 V pulses and hence less fuel is atomized.
