Publication number: 20070169708Abstract: This invention is a process for producing superior animal litter and floor coverings for human shelters from citrus peels and a method of removing waste citrus peels from a citrus juice processing plant in a cost-efficient, recyclable, environmentally-sound manner. Because the process only uses one natural and recyclable product, it avoids the problems associated with other processes which use non-recyclable products, require more than one substance to be mixed together, or rely upon wood or other potentially sharp objects which can injure the animal or pet. Instead, this process takes citrus peels, a waste product so therefore one which is inexpensive and readily available, and processes it in an assembly line fashion with advanced machinery and processing techniques, such that it results in a naturally rounded object with no sharp ends or edges, which absorbs wetness from urine and feces and successfully masks the smell at the same time.Type: ApplicationFiled: January 26, 2006Publication date: July 26, 2007Inventor: Bradford Richdale

Publication number: 20070169737Abstract: A multiple spark pattern internal combustion initiation device includes a body defining a prechamber and a plurality of orifices from the prechamber. The device includes at least two electrical circuits which each form a spark gap with an electrical ground inside the prechamber, operable to create a plurality of different spark patterns. The device may be part of an internal combustion engine which includes a housing with a combustion chamber connected to the prechamber, and means for supplying a lean gaseous fuel mixture into the combustion chamber.Type: ApplicationFiled: January 20, 2006Publication date: July 26, 2007Inventors: Weidong Gong, Scott Fiveland, Brett Bailey

Publication number: 20070169738Abstract: An intake port for a 4-cycle engine includes an intake port base integrally formed with a cylinder head, and an intake port forming member that forms an intake port together with the intake port base. The area of the cross section of the intake port orthogonal to a centerline of the intake port is substantially uniform from an open intake side thereof toward a combustion chamber. The angle made by the centerline of the intake port and an intake valve shaft is larger than 90° from a viewpoint of the intake valve. Thereby, the 4-cycle engine can output high power with the intake port shape, as formed with above mentioned configuration, that reduces intake resistance and that uses simple design molds. More specifically, the engine can reliably prevent condensed fuel from remaining in the intake port to avoid incomplete combustion of gas.Type: ApplicationFiled: August 29, 2006Publication date: July 26, 2007Applicant: FUJI ROBIN KABUSHIKI KAISYAInventor: Masaki Sugiyama

Publication number: 20070169739Abstract: A reciprocating-piston internal combustion engine has a crank drive and a transmission lever indirectly coupled with the piston and intersecting the cylinder axis. The lever is articulated onto the crank drive's connecting rod and onto an adjustable bearing guided in the cylinder block. For greater variation of the translation of movements between crank drive and piston, the pulling and pushing rod connected with the piston has a guide at its end facing the transmission lever. The guide is preferably a pivotally-mounted slide shoe that engages into a guide extending along the transmission lever. The transmission lever is pivotally connected with the crankshaft connecting rod and connected with a setting drive for variably setting the articulation of the pulling and pushing rod on the transmission lever. A guide lever pivotally connected with the pulling and pushing rod and pivotally articulated onto the cylinder block guides the pulling and pushing rod.Type: ApplicationFiled: January 23, 2007Publication date: July 26, 2007Inventors: Markus Meyer, Frank Van Der Seylberg

Publication number: 20070169740Abstract: A pre-combustion chamber for an engine is made more simply removable from the cylinder head by integrating the chamber design and not threading the assembly to the head. The assembly is provided as an integrated design using a seal that helps dissipate heat from the spark plug and a cover that is held down by flange bolts that extend into threaded bores into the head in a location more removed from the heat generated in the chamber. As a result the chamber is more simply installed and removed without damage to the head.Type: ApplicationFiled: January 20, 2006Publication date: July 26, 2007Inventor: Thomas Riggs

Publication number: 20070169741Abstract: The present disclosure provides an engine operating method and high power density internal combustion engine, including an engine housing with a plurality of cylinders. Fuel injectors are provided and disposed at least partially within each cylinder, and configured to inject fuel such as diesel, JP8 or another fuel therein for compression ignition. The engine is configured to burn a quantity of injected fuel to yield at least about 150 horsepower per liter of engine displacement at a smoke output of less than about 0.4 grams, and in some cases less than about 0.75 grams, smoke per horsepower-hour, at a fuel consumption of less than about 250 grams fuel per kilowatt-hour output of the engine.Type: ApplicationFiled: March 30, 2007Publication date: July 26, 2007Inventors: John Vachon, Carl-Anders Hergart

Publication number: 20070169742Abstract: Disclosed is a method for operating an internal combustion engine, wherein fuel is injected in a pre-injection and main injection process. According to the invention, pre-injection occurs in the intermediate compression stroke of the internal combustion engine. Main injection is carried out in an intake synchronous manner. The invention can be used for internal combustion engines, particularly for passenger cars and commercial vehicles.Type: ApplicationFiled: September 2, 2004Publication date: July 26, 2007Inventors: Goetz Brachert, Ruediger Herweg, Kai Kanning, Matthias Pfau, Jochen Schaeflein, Hans-Juergen Weimann

Publication number: 20070169743Abstract: An engine-driven work machine having a target engine speed selection unit and a control unit. The target engine speed selection unit selects and specifies an arbitrary target engine speed from among a plurality of target engine speeds that is set in stepwise fashion. The control unit electrically controls the opening and closing of a throttle valve so that the actual engine speed conforms to the specified target engine speed.Type: ApplicationFiled: January 17, 2007Publication date: July 26, 2007Applicant: Honda Motor Co., Ltd.Inventors: Hiroshi Kobayashi, Masayuki Sasaoka, Toshio Inoue, Kenzo Shimada, Yoshinori Maekawa
