摘要

The method involves designing of a swirl duct valve for increasing the swirl amplitude by small valve lifts, particularly in an area between 2 millimeters and 4 millimeters. A soot number is adjusted by different opening positions of the swirl flap in an operating point. An effective medium pressure of 2 bars and a constant nitrogen oxides untreated emission or a soot number are adjusted in an operating point. An independent claim is included for an internal combustion engine has a compression ignition.
