Claim 29

A reactor as set forth in claim 6, wherein said inner pipe fixed to the engine block or exhaust manifold has smaller outer diameter than the inner diameter of said pipe member so as not to restrict movement of said pipe member in the axial direction and in a direction normal to its axis.

Claim 30

A reactor as set forth in claim 15, wherein said inner pipe sealingly engages said pipe member so that said reaction chamber and said adiabatic space remains sealed during relative movement between said inner pipe and said pipe member in the direction normal to their axis.

Claim 31

A reactor as set forth in claim 15, wherein said inner pipe has a smaller outer diameter than the inner diameter of said pipe member, and a ring is inserted between said pipe member and said inner pipe so that said reaction chamber and said adiabatic space are maintained sealed, while said inner pipe is moved relative to said pipe member in a direction normal to the axis thereof.
