An insulated engine shrouding encloses a combustion chamber and piston assembly. The engine shrouding includes air transfer ducts that channel air from a condenser, where the air is preheated, to intakes of air-to-air heat exchangers where the air is further heated. The heat exchangers direct the hot air to atomizer/igniter assemblies in a burner to generate combustion gases in the combustion chamber. The engine shrouding further includes return ducts that direct the combustion exhaust gases through an exhaust portion of the air-to-air heat exchangers. Heat from the exhaust gases is used to preheat the air being directed through the intakes.
