Abstract:
An eddy flow generator adapted to be mounted at a joint between a fuel injector and an intake manifold of an internal combustion engine, the eddy flow generator comprising:a base having a first side face, an opposite side face and a periphery, with the base adapted to be located at the joint between the fuel injector and the intake manifold with the fuel injector abutting with the first side face and the intake manifold abutting with the opposite side face; multiple passages for receiving air and fuel and each defined in the base extending between the first and second side faces and spaced inwardly of the periphery, with each of the multiple passages adapted to correspond to and communicate with one of multiple air paths of the intake manifold, each passage having multiple spirally formed blades integrally formed on one of the side faces of the base and extending outward of the one of the side faces to direct air flow in a spiral pattern, whereby the air coming from the intake manifold is able to fully mix with the fuel via movement of the air flow in the spiral pattern.
