    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.

    Abstract: A carburetor communicating with an intake manifold of an internal-combustion engine receives preheated air through an annular filter heated electrically during a cold-starting phase and fluidically with the engine in operating condition, the air passing around a flap valve--acting as an automatic choke--into a mixing chamber to aspirate a volatile hydrocarbon such as gasoline from a main fuel tank. The flap valve is heated in the same manner as the filter, and so are a pair of accelerator-controlled throttle valves separating the mixing chamber from a further compartment into which a heavier hydrocarbon such as diesel oil is aspirated in vaporized form after passing from an ancillary fuel tank through a boiling cylinder heated by the exhaust gases of the engine. The fuel/air mixture enriched with the diesel-oil vapors enters the intake manifold where any residual droplets are intercepted by a stationary plate which is also heated and, like the throttle valves, is coated with an adsorbent layer of metal gauze or wicking to promote evaporation. The boiling cylinder, located in the exhaust duct or a branch thereof, may be journaled for rotation by the exhaust gases or may have a recirculating conduit including a pump driven by these gases for preventing the accumulation of liquid hydrocarbons therein.

    Abstract: A device for use in association with a carburetor of the type used for supplying fuel at the intake manifold of a gasoline internal combustion engine has an annular chamber at the exit port of the carburetor, adapted to collect uncarbureted raw gasoline particles or globules for drainage through an external vaporizing system under the influence of the vacuum created at the intake manifold during operation of the engine for reintroduction as vaporized fuel at the intake manifold, thereby converting raw gasoline, otherwise wastefully fed to the engine, into efficiently combustible fuel.
