Method of processing waste product into fuel

Abstract

Fuels used may be derived from existing waste streams such as animal wastes and streams of discarded or unwanted animal byproducts generated at animal slaughterhouses. A method of processing organic waste products into fuel includes homogenizing the waste products. The waste products are heated and pressurized. Water is removed from the waste products. Selected constituent of the waste products are separated from the waste products into a waste stream. The waste stream is blended with a fuel to form a bio-fuel mixture.

 (a) homogenizing the waste products;   (b) heating and pressurizing the waste products;   (c) removal of water from the waste products;   (d) separation of a selected constituent of the waste products from the waste products into a waste stream; and   (e) blending a fuel with the waste stream to form a bio-fuel mixture.   
   
   
       2 . The method of  claim 1 , wherein the selected constituent is fats and oils. 
   
   
       3 . The method of  claim 1 , wherein the selected constituent is proteins.

       5 . A method of processing waste products from biological sources into fuel comprising:
 (a) homogenizing the waste products;   (b) heating and pressurizing the waste products;   (c) removal of water from the waste products;   (d) separation of fats and oils from the waste products into a first waste stream;   (e) separation of proteins from the waste products into a second waste stream;   (f) separation of cellulose from the waste products into a third waste stream; and   (g) blending a fuel with at least one of the first, second, or third waste streams to form a bio-fuel mixture.   
   
   
       6 . An engine having an adjustable displacement comprising:
 (a) a housing;   (b) a crank ring rotatably disposed within the housing;   (c) a piston pivotally coupled to the crank ring; and   (d) a cylinder rotor rotatably disposed within the housing and having a cylinder for reciprocatingly receiving the piston, wherein a distance between a rotational center of the crank ring relative to a rotational center of the cylinder rotor is adjustable to selectively adjust a displacement of the engine.   
   
   
       7 . The engine of  claim 6 , further comprising an eccentric displacement adjustment ring adjustably disposed within the housing, wherein an angular displacement of the eccentric displacement adjustment ring is adjustable to selectively adjust the distance between the rotational center of the crank ring relative to the rotational center of the cylinder rotor. 
   
   
       8 . An engine having an adjustable displacement comprising:
 (a) a housing;   (b) a crank ring rotatably disposed within the housing about a rotational center;   (c) a piston pivotally coupled to the crank ring; and   (d) a cylinder rotor rotatably disposed within the housing and having a cylinder for reciprocatingly receiving the piston, wherein the cylinder rotor rotates about a rotational center spaced from the rotational center of the crank ring such that rotation of the crank ring and the cylinder rotor causes reciprocal motion of the piston within the cylinder, and wherein the crank ring is adjustably mounted within the housing to permit the moving of the rotational center of the crank ring relative to the rotational center of the cylinder rotor to selectively adjust a displacement of the engine.   
   
   
       9 . The engine of  claim 8 , further comprising an eccentric displacement adjustment ring adjustably disposed within the housing, wherein an angular displacement of the eccentric displacement adjustment ring may be adjusted to selectively displace the crank ring such that the rotational center of the crank ring is moved, causing the displacement of the engine to be adjusted. 
   
   
       10 . The engine of  claim 8 , wherein the crank ring is adjustable during operation of the engine such that the displacement of the engine may be adjusted without stopping of the engine. 
   
   
       11 . An engine having an adjustable displacement comprising:
 (a) a housing having a center;   (b) a cylinder rotor disposed within the housing and rotatable about a rotational center;   (c) a plurality of cylinders disposed within the cylinder rotor, the cylinders substantially radially oriented relative to the rotational center; and   (d) a plurality of pistons disposed within the cylinders, each of the pistons reciprocal within one of the cylinders along a predetermined stroke length to compress a gas as the piston moves toward the rotational center, wherein the predetermined stroke length of each of the pistons is adjustable to adjust a displacement of the engine.   
   
   
       12 . The engine of  claim 11 , wherein each of the pistons are coupled to a crank disposed within the housing, wherein the predetermined stroke length of each piston is adjusted by rotating the crank. 
   
   
       13 . A vehicle comprising:
 (a) a combustion engine;   (b) a compressor;   (c) a drive wheel; and   (d) a drive assembly coupling the combustion engine, the compressor, and the drive wheel in power transfer communication with one another such that the drive wheel is adapted to selectively drive the compressor during a braking operation, and the combustion engine is adapted to drive the compressor and the drive wheel to propel the vehicle forward during non-braking operations.   
   
   
       14 . The vehicle of  claim 13 , wherein the compressor is adapted to compress a fluid for use in driving the drive wheel to aid in propelling the vehicle forward.
