IMPROVING THE INJECTION CHARACTERISTICS OF FUEL NOZZLES

Dorinel POPA, Cristin-Olimpiu MORARIU

Abstract


Reducing the level of pollution in automobiles is mainly achieved by constructive optimization of the components of the injection system, which have the greatest influence in this regard, namely by improving the flow characteristics through the fuel nozzle holes. This improvement can be achieved by vibrations assisted abrasive finishing of the flow surfaces using abrasive fluxes. Through this process, a finishing - rounding - of the fuel flow holes is achieved, causing the removal of cavitation effect.
