Patent number: 9222433Abstract: An apparatus includes a recreational vehicle genset having an engine and a generator. The apparatus includes a fuel injection system having a primary fuel reservoir, a secondary fuel reservoir, and a fill pump that receives fuel from a primary fuel reservoir and is fluidly coupled to the secondary fuel reservoir at the pump outlet. The apparatus includes a reservoir fuel indicator that provides a fuel amount signal corresponding to the fuel in the secondary fuel reservoir, and a pressure regulator that relieves pressure in the secondary fuel reservoir at a threshold relief pressure. The apparatus includes an injection pump that provides pressurized fuel from the secondary fuel reservoir to a fuel injector for the engine. The apparatus further includes a controller having a pump regulation module that interprets the fuel amount signal, and that selectively provides a fill pump operation command in response to the fuel amount signal.Type: GrantFiled: October 31, 2011Date of Patent: December 29, 2015Assignee: CUMMINS POWER GENERATION IP, INC.Inventors: David T.

Patent number: 8683980Abstract: An open or closed loop EFI system, integrated on a genset engine or any internal combustion engine, with an electrical sensor and crank position sensor is described. Since a genset engine's exhaust emissions and general performance are a function of spark timing, integration of electrical and crank position sensors on a genset engine provides optimal engine performance and efficiency when the electrical draws fluctuate. The electrical sensor and crank position sensor send data to the electronic control unit (ECU), and this data is used to determine the optimal air-to-fuel ratio (AFR) and optimal spark timing. The ECU varies the spark timing in accordance with the speed and load of the engine and actuates the fuel injector to send the correct amount of atomized fuel to mix with the air flow to be combusted allowing the engine to meet performance.Type: GrantFiled: January 28, 2010Date of Patent: April 1, 2014Assignee: Cummins Power Generation, Inc.Inventors: David T. Falkowski, Jeffrey D. Peterson, Matthew J. Ethen, Kristopher G. Knight, Peter J. Vancalligan

Publication number: 20110179779Abstract: An exhaust system that can improve emissions treatment by reducing certain emissions species. The exhaust system draws air into the exhaust system from an air source, when exhaust pressure decreases to a threshold so that air can enter the exhaust system. The exhaust system is in a genset engine. The air source is a pressurized air source, such as an existing fan of the genset engine. A portion of the air generated by the air source is pulled off so that it flows directly toward the exhaust system, using a one-way valve and conduit that fluidly connects the air source to the exhaust system.Type: ApplicationFiled: January 28, 2010Publication date: July 28, 2011Applicant: CUMMINS POWER GENERATION, INC.Inventors: David T.

Patent number: 4861040Abstract: A multi-level board game is set forth wherein a pair of players each are protective of their individual castle or "Keep". Each player is provided with a plurality of tokens representing Vassals, a Wizard, a plurality of Archers, and an Earthstone. The object of the game is to travel the board game from a player's Home Keep to an opposing player's Keep or to alternatively remove the opponents players, overpower the opponents Earthstone, or move the Demon player to overtake an opponent's Earthstone. The players are moved by a predetermined orientation relative to each other or alternatively may use pyramidal dice to determine the number and type of movement employed. Each player's Wizard and three Archers have powers to destroy opponents during the course of the game.Type: GrantFiled: September 8, 1988Date of Patent: August 29, 1989Inventor: Jeffrey D. Peterson
