1. A toroidal induction diffuser for enhancing mixing of engine intake air and fuel in an engine cylinder, comprising:
an engine intake port having a first longitudinal axis;
an engine intake runner upstream of the engine intake port having a second longitudinal axis;
a toroidal structure located around one of the first longitudinal axis and the second longitudinal axis;
wherein the toroidal structure includes a first one or more holes for introducing a first fuel flow into the engine intake port or the engine intake runner; and
one or more cross branch structures extending radially from the toroidal structure to one of the engine intake port or the engine intake runner, wherein the one or more cross branch structures comprise a second one or more holes for introducing a second fuel flow into the engine intake port or the engine intake runner.
