STABLE FUEL BURNER FOR PREHEATING INTAKE AIR OF INTERNAL COMBUSTION ENGINE ABSTRACT OF THE INVENTION A fuel burner for producing a highly stable flame and predictable heat output for use within an environment subject to disruptive pressure changes and ambient air current flow such as the intake manifold of an internal combustion engine. The burner includes a nozzle for forming a cone shaped fuel spray and a flame surrounding shroud having a combustion gas outlet wherein the shroud is shaped to cause a toroidal pattern of recirculating combustion gases to be formed within the shroud. A circumferential lip surrounding the combustion gas outlet creates a low pressure zone within the shroud to cause a counterflow of ambient air into the shroud through the outlet in a cylindrical pattern coaxial with the exiting combustion gases.
