Control of temperature of air efflux from an air outlet is by control of the oscillation of a fluidic oscillator. Directionality of efflux is by control of nibs at the outlet.

An air discharge nozzle and method for vehicles having a grill (21') which has a high degree of visual opacity to enhance design aesthetics, low impedance to air flow so that the face velocity remains high, and which does not significantly affect directionality of the air as imparted to the air stream by an upstream control mechanism. The grill (21') is comprised of a monolayer of polygonal cells in an array of cells, each cell being bounded by planar walls having a depth "L" interstitial thickness "T" and a diameter or major dimension "D", wherein the interstitial depth L is short enough such that the planar walls do not act as vanes to significantly affect directionality of the air, the interstitial thickness T has a value such that the impedance to air flow is low, and the length to diameter ratio L/D is no greater than about 0. 7 and no less than about 0. 3, such that the relative visual opacity of the grill when viewed from any angle is high.

A bistable fluidic switch is switched from its stable state by a pin inserted in the power nozzle of the bistable fluidic switch, the pin being controlled by an electromagnetic actuator which is controlled from an electronic computer. The fluidic switch element has a cross-over type interaction region and a common outlet leading to a pair of output passageways, one of which returns fuel to the supply tank, and the other of which leads to the air intake manifold of the engine. Air is introduced into the output passageway leading to the engine so as to air atomize the fuel before injection of same into the air intake manifold.
