摘要

PURPOSE: A fuel injector nozzle for a diesel engine is provided to reduce amount of NOx by uniformly injecting the fuel into the entire space of a combustion chamber.;CONSTITUTION: A fuel injector nozzle for a diesel engine comprises a nozzle body(20), and a plurality of outlet holes(40). The plurality of outlet holes comprises a plurality of first and second outlet holes. The first outlet holes are placed on a leading end of the nozzle body. The second outlet holes are placed below the plurality of first outlet holes. The plurality of first and the second outlet holes is placed in a zigzag formation. The plurality of first outlet holes is formed along a first spiral trajectory proceeding to a lower center of the leading end. The plurality of second outlet holes is formed along a second spiral trajectory proceeding to the lower center of the leading end.;COPYRIGHT KIPO 2012
