Abstract
A flow directing annular nozzle inlet port for an internal combustion engine includes a tubular wall defining an open passage connecting with an associated engine combustion chamber and having a plurality of angularly disposed nozzles aligned in helical fashion to direct inlet fluid in a manner to define, supplement and reinforce a single lead pattern of helical flow in the open passage with a predetermined primary flow path leading to discharge into the cylinder in a primary flow direction determined by the primary flow path in the passage. To develop cylinder swirl, the discharge flow direction is preferably oriented circumferentially tangential to the cylinder wall.
