A heat engine can have a fuel selector valve for selecting between a first fuel and a second fuel. Making the selection with the fuel selector valve can also determine a flow path through the heat engine, there being two different paths, each configured for a different fuel. A burner nozzle can form a single unit with the fuel selector valve. In some embodiments the burner nozzle can also form a single unit with an outlet valve. |
