Abstract: An air fuel injection system for an internal combustion engine includes a plurality of fuel injectors supplied with fuel from a common fuel supply and supplied with air for producing a fuel spray pattern immediately upstream of an inlet valve to the combustion bowl of one of the engines cylinders and downstream of the induction air passage which supplies combustion air to the combustion bowl. The injection air supply is provided by an integral motor pump assembly having an electric motor driving a balanced lobe vane pump. The pump motor is electrically driven to charge the fuel injectors with high pressure air before the engine is started and independent of engine operation. The balanced lobe vane pump has an inlet connected to the PVC valve of the engine to provide a oil mist lubrication of the operative wear surfaces of the vane pump and the vane pump has an inlet connected to an air manifold for supplying lower noise and pulse air pressure thereto.

Abstract: A bumper fastening system for a composite SRIM (structural reaction injected molded) member made up of a core member covered by a reinforced outer cover has a fastening cup connected to the reinforced outer cover by a layer of adhesive material. The fastening cup is a hollow rectangle with a flat end plate which is covered by a layer of adhesive for connection to the composite SRIM or to a metal bumper by spot welds.

Abstract: A process of separating vinyl skin from a foam backing and recovering the separated components by granulating the plastics composite into small chips, mixing the chips with a quantity of water in a vessel to swell and break the cell structure of the foam at the foam/vinyl interface resulting in flotation of the foam bits and sinking of the heavier vinyl bits. The separated foam is recovered by adding additional water to flow the foam material from the mix vessel. The vinyl is then removed from the bottom of the vessel and the separated components are dried for recycling or improved disposal purposes.
