Abstract: A system for integrating air injection and exhaust gas recirculation in the internal combustion engines of vehicles, such as in a contemporary automobile or truck. The integration system includes conduit members connecting a source of pressurized ambient air with the exhaust system of the engine, to supply the ambient air into the exhaust system during deceleration. A flow control member prevents the flow of the exhaust gases backward along the conduit members toward the pressurized air source, during acceleration or cruising to promote flow of the exhaust gases through the EGR valve and into the intake system of the engine.

Abstract: A clamp system for maintaining an end of a high temperature fluid bearing tube in substantially sealing engagement with a surface and in substantial alignment with an aperture in the surface positioned substantially transverse to the tube. A bracket member is provided to hold the end of the tube against the surface. An annular flange is provided on the end of the tube, to form the seal and provide a surface against which the bracket member pushes. The annular flange is advantageously configured so as to position the seal radially away from the tube so as to reduce transmission of heat from the fluid within the tube to the seal, to, in turn, protect the material of the mating surfaces from heat degradation.
