Abstract
A high pressure fuel injector has a swirl generator with a metering disk upstream of the valve seat. The disks function to redirect the axially flowing fuel through the injector into a tangential fuel flow. As the fuel moves past the needle valve and the valve seat, the narrow cross section imparts a higher velocity to the fuel to atomize the fuel. As the fuel leaves the swirl generator and is ejected from the injector, the fuel forms a hollow conical sheet containing atomized fuel.
