<p>An external combustion engine comprises an engine head to be heated on its outer surface, a burner housing placed over the head and connected thereto by mounting means, a burner element provided in the housing, a fuel feed delimiting an incoming flow path for delivering a gas-air mixture to an inlet of the burner element, a combustion space present at a front side of the burner element and extending along a first part of the outer surface of the engine head, a heat exchange space in flow communication with the combustion space and extending along a second part of the outer surface of the engine head, an outlet in flow communication with the heat exchange space, a gasket provided between the mounting means of the engine head and burner housing, and a cooling chamber extending along the mounting means for cooling the gasket. The combustion space and the heat exchange space form an outgoing flow path for hot combustion gases to exchange heat towards the engine head. A starting part of the fuel feed extends through the cooling chamber for cooling the gasket with a flow of the gas-air mixture before this mixture is delivered to the inlet of the burner element.</p> |
