ABSTRACT:
A cold start burner for prewarming components of an engine, especially for prewarming engine exhaust upstream of a catalytic converter. The device generally includes a pot shaped (i.e., cylindrical) burn chamber and a similarly shaped preheat chamber positioned concentrically around the burn chamber. An igniter is positioned within the burn chamber, and fuel is supplied into the burn chamber to be ignited by the igniter. Air is directed into the relatively cool preheat chamber and is then directed by the cooling of the preheat chamber to a plurality of openings extending through the side wall of the burn chamber. The air passes through the openings and into the burn chamber where it is preheated and then directed into an exhaust line upstream of the catalytic converter. Excess (i.e., unburned) fuel is collected in a reservoir formed within the burn chamber.
