Filed:

Dec 3, 1979

Appl. No.:

6/099340

Inventors:

International Classification:

F02B 4504
F02D 1904

US Classification:

Abstract:

An improved solid fuel carburetor is disclosed for an internal combustion engine or furnace. A solid fuel supply mechanism advances a cake of compressed, powdered, combustible fuel into an operative position in a mixing chamber. A rotary brush mechanism positioned proximately to the fuel supply mechanism, contacts the fuel cake and abrasively removes fuel particles therefrom in the mixing chamber. An air supply is provided proximate to the brush mechanism for mixing air with the removed fuel particles forming a combustible mixture in the mixing chamber. A delivery mechanism is connected between the mixing chamber and internal combustion engine or furnace, for delivering the combustible mixture to the combustion chamber. The resultant solid fuel carburetor provides a more convenient and safe mechanism for delivering solid state combustible materials to an internal combustion engine or furnace.

Abstract:

An air boat has a power unit including a typical automotive engine and a pylon mounted on the engine clutch housing and carrying an aircraft type propeller at its upper end. Belts or a chain housed within the pylon drivingly connect the motor and propeller. The motor and pylon are preferably mounted on a base which is removably mounted on the air boat hull. Preferably, the base also carries a cooling system radiator, fuel tank, and typical engine accessories so that the entire power unit may be installed in and removed from the air boat as an integral unit, thus facilitating servicing of the power unit at a convenient location out of the boat hull with the power unit fully assembled and ready to run when it is returned to the air boat.
