Internal combustion engine i.e. rotary piston engine, has isolating elements and engine components such as piston, of combustion chamber structure made of metallic and/or high resistant alloy such as heat resistant steel and titanium

摘要

The engine has isolating elements provided in combustion chamber limiting walls i.e. cylinder walls. The elements and engine components such as piston (8), engine housing, cylinder sleeve and cylinder head, of a combustion chamber structure are made of metallic and/or high resistant alloy (2) such as main group steel, heat resistant steel and titanium. The elements are designed as a lining of solid and/or foam material. The isolating elements exhibit a compact outer layer on a foam element. The components are made of nickel/cobalt alloy used as a nonferrous-base metal.
