Experimental investigation has been made of screw swirl nozzle for diesel engine. Compared with single screw swirl nozzle, triple screw swirl nozzle can produce finer spray pattern. But the atomizing quality under low injection pressure was poor at the beginning stage of injection. To improve of the defect, the swirl chamber of the single screw swirl nozzle must be made as small as possible and the needle lift be lowered.
