This paper presents the results of engine experiments and spray observations on a VCO nozzle. Two types of VCO nozzles having different hole shapes were investigated. One had a straight step hole (the VCO-S) and the other had a tapered step hole (the VCO-T).Both VCO nozzles could greatly reduce HC emissions in comparison to a standard nozzle. The VCO-S nozzle could reduce NOx emissions more than the VCO-T nozzle, and its spray penetration was shorter than that of the VCO-T.
