Abstract: A PCV circuit for an internal combustion engine is modified to deliver the PCV fluid to an atomization chamber which also receives fuel from an electronic fuel injector tapped into the main vehicle fuel supply. The fuel from the injector is thoroughly vaporized in and/or immediately downstream of the chamber and conveyed to the vehicle intake manifold. A switch cuts off operation of the fuel injector at high load/high throttle setting conditions. The injector operates at a constant frequency with a selected ON time.

Abstract: A PCV circuit for an internal combustion engine is modified to deliver the PCV fluid to an atomization chamber which also receives fuel from an electronic fuel injector tapped into the main vehicle fuel supply. The fuel from the injector is thoroughly vaporized in and/or immediately downstream of the chamber and conveyed to the vehicle intake manifold. In one embodiment, a switch cuts off operation of the fuel injector at high load/high throttle setting conditions. In another embodiment, injected fuel is measured with increased engine load. The injector operates at a constant frequency with a variable ON time.

Abstract: A dental appliance whose labial surface has the contour, shape and color of a complete tooth thus adapting the appliance to camouflage orthodontic hardware. This dental appliance is adapted to be detachably secured to commonly used orthodontic hardware by any one of several securing means including a resilient tongue, pins which are received by mating recesses, and frictional retention of a portion of the orthodontic hardware within cavities on the lingual side of the cosmetic orthodontic appliance. The body of the dental appliance is formed from a material having sufficient mechanical strength to withstand mounting and demounting by a patient as desired. The pins received by the mating recesses may be adjustable pins for adjusting the distance and the angle between the cosmetic orthodontic device and the orthodontic hardware. The cosmetic orthodontic device may also be adapted to resemble a plurality of teeth and/or a plurality of teeth and gingiva.
