Title: DUAL FUNCTION FUEL INJECTOR WITH TUNABLE INTRA-PORT AIR AND FUEL FLOW CONTROL
Abstract:
In the preferred embodiments an air flow diverting blade is integral to a base that doubles as a collar designed to coaxially attach to the tip end of a typical port fuel injector for internal combustion engines. Upon simple manual manipulation of the set rotational angle of the typically externally exposed portion of the port fuel injector along its longitudinal axis, as typical modern port injection systems allow after installation, the angle of the intra-port flow diverting blade can be selectively varied to either straighten existing swirl and increase top end flow, or, introduce lateral directional swirl to whatever desired angle and intensity in either direction is desired. The flow diverting blade can be configured to divert flow around the intake valve stem, guide and guide boss in such a manner to optimize the overall flow dimension of the induction system of a typical internal combustion engine.
