ABSTRACT:
Disclosed is a method of operating a catalytic ignition internal combustion engine wherein the fuel is injected into a combustion chamber at a time near maximum compression such that at least part of the fuel impinges upon an oxidation catalyst surface comprising a portion of the wall of said combustion chamber, said catalytic surface being insulated from the surroundings external to the combustion chamber by a low thermal conductivity material, said catalytic surface preferably comprising platinum. Also disclosed are combustion chambers constructed specially for the use of this method and the methods of constructing them.
