Abstract: The present invention relates to a process for the production of polyurethanes where (a) polyisocyanate, (b) polymeric compounds having groups reactive toward isocyanates, (c) catalysts, (d) a CH-acidic compound of the general formula R1—CH2—R2, where R1 and R2 independently of one another are an electron-withdrawing moiety of the general formula —C(O)—R3 or —CN, where the moiety R3 is selected from the group consisting of —NH2, —NH—R4—NR5R6, OR7 or R8, where R4, R5, R6, R7, and R8 are independently selected from the group consisting of aliphatic, araliphatic or aromatic hydrocarbons, which may have substitution, and optionally (e) blowing agent, (f) chain extender and/or crosslinking agent, and (g) auxiliaries and/or additives are mixed to give a reaction mixture, and the reaction mixture is allowed to complete a reaction to give the polyurethane. The present invention further relates to polyurethanes produced by this process and to the use of these polyurethanes in the interior of means of transport.

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.
