Abstract:
1. A throttle for an internal combustion engine, comprising: a plurality of vanes disposed transversely to a main direction of flow of fluid through said throttle, each said vane having an axis about which it is configured to rotate, a plurality of vane spindle gears, each said vane spindle gear operatively connected to a vane, and a throttle ring operatively connected to said plurality of vane spindle gears such that rotation of said throttle ring effects a rotation of each vane spindle gear, thereby effecting movement of each said vane; each said vane is configured to control a degree of flow of fluid through said throttle and each said vane is also configured to generate a vortex in a fluid allowed to flow through said throttle, and said vanes are arranged to rotate about their axes under the control of a user such that in use said vanes control the amount of an air/fuel mixture going to an engine and control the degree of rotation of said air/fuel mixture; wherein one of said vane spindle gears is arranged as a primary drive gear configured to be controlled by a user and such that when said primary drive gear is rotated by a user the throttle ring also rotates.
