ABSTRACT:
The invention is in a transfer pipe for passing engine exhaust gas from an engine exhaust manifold to a turbine inlet side of an exhaust gas driven turbine air compressor. The transfer pipe is formed from a material, such as steel, that is appropriate for use in transferring hot engine exhaust gas and provides for mounting on one end across the turbine inlet The opposite transfer pipe end is arranged for fitting into an open collar end of an exhaust gas conduit that receives exhaust gas from the engine exhaust manifold, and includes a circumferential arcuate section for providing a metal to metal seal with the collar interior wall while allowing the transfer pipe to be tilted relative to the collar interior wall without breaking the seal. The transfer pipe provides a uniform cross sectional area along its length and is widened through a uniform arc at bends to maintain that uniform cross section along the entire pipe length, minimizing creation of turbulence in the gas flow as would occur at a point where the pipe is narrowed and then expands.
