Abstract
A vehicular air intake is configured to produce a turbulent intake air flow in a cylinder of an engine. The air flow may be provided as a vortex. A throttle valve, for controlling an amount of intake air provided to the engine, has a pivot shaft with an axis which is offset from a center axis of an air intake passage in which the throttle valve is installed, and a throttle plate affixed to the pivot shaft. The pivot axis is offset and spaced away from the central axis of the throttle body such that a first portion of a throttle plate disposed on a first side of the pivot shaft, is larger than a second portion of the throttle plate disposed on a second side of the pivot shaft. This arrangement provides the non-uniform turbulent air flow into the engine.
