 About 30 per cent. of the heating value of the fuel passes into the metal of the engine in this way, and it is necessary to provide means for its removal as fast as it goes in. In all engines hitherto made (except the small air-cooled engines) the removal...  Gas Review - Side 361914Uten tilgangsbegrensning - Om denne boken
