Abstract
A combustion chamber of an internal combustion engine includes a contoured surface that defines a plurality of deflection foils. The contoured surface distributes fuel spray into portions directed toward one of the deflection foils. Each deflection foil re-directs their respective portion of the fuel spray into a combined radial path that swirls about a center of the combustion chamber. Each of the deflection foils defines a flow path and a foil axis. The flow path includes an entrance segment and an exit segment. The entrance segment directs a portion of the fuel spray radially away from the center of the combustion chamber, and the exit segment directs the portion of the fuel spray substantially tangential relative to the combined radial path of the re-directed portions of the fuel spray.
