Abstract: The present invention relates to a thermally insulated internal combustion engine where a polyurethane foam entirely or to some extent surrounds the external surface of one or more parts of the internal combustion engine. The present invention further relates to a process for the production of a thermally insulated internal combustion engine by taking an engine part, using a mold to surround the part that is to be surrounded with foam within the internal combustion engine part, thus producing a cavity between engine part and mold, charging a polyurethane reaction mixture into the cavity, allowing the polyurethane reaction mixture to complete its reaction to give a polyurethane foam, and removing the mold.
