This patent describes an improvement in combination with an internal combustion engine having a throttle body with a fluid passageway and a butterfly type valve plate which is pivotally secured within the passageway for rotation about a valve axis extending perpendicularly to the centerline of the flow passage, the valve plate having a closed operative position relative to the passageway of the throttle body in which the peripheral edge of the valve plate engages the passageway defining wall, the valve plate being selectively pivoted about the axis from the closed position to a more open position characterized by movement of substantially half the peripheral edge in a generally upstream direction and movement of substantially half of the peripheral edge in a generally downstream direction. The improvement comprises a venturi nozzle symmetrically positioned in the passageway and located downstream of the closed position of the valve plate and having a known standard configuration which does not substantially diminish flow through the passageway.
