Patent number: 9359968Abstract: An apparatus for dithering fuel into an internal combustion engine includes a turbine that is powered by the internal combustion engine and a first fuel injector that injects a first fuel into an air stream to create a fuel/air stream. The apparatus also includes an air/fuel compressor that provides a compressed fuel/air stream to the internal combustion engine. The air/fuel compressor is powered by the turbine, and the air/fuel compressor compresses the fuel/air stream to create the compressed fuel/air stream. Additionally, the apparatus includes a second fuel injector that injects a second fuel into the compressed fuel/air stream prior to the compressed fuel/air stream entering the engine and after the compressed fuel/air stream exits the air/fuel compressor.Type: GrantFiled: February 21, 2014Date of Patent: June 7, 2016Assignee: CUMMINS IP, INC.Inventors: Leon A.

Publication number: 20140260203Abstract: A system and method for reforming a portion of an exhaust gas stream in an internal combustion engine system. An exhaust gas recirculation assembly divides the exhaust gas stream into a recycle stream and a vent stream. A mixer in fluid receiving communication with the recycle stream forms a combination stream by mixing a gaseous fuel stream with the recycle stream. A thermochemical recuperator component fluidly connects to the mixer and includes a first flow path and a second flow path. The first flow path has a catalyst through which the combination stream flows to create a reformate stream, and the second flow path has a heat transfer area for transferring heat from the vent stream to the combination stream.Type: ApplicationFiled: March 14, 2014Publication date: September 18, 2014Applicant: Cummins IP, Inc.Inventors: Leon A.

Patent number: 8757133Abstract: A gaseous fuel mixer for an internal combustion engine includes a mixer body and a mixer element supported in a mixer passage formed in the mixer body. The gaseous fuel mixer attaches to an intake manifold at a first end and receives intake air at a second end. A distal end of the mixer element accepts gaseous fuel from a manifold passage extending from a port positioned in the intake manifold. The gaseous fuel flows through the mixer element and then through a plurality of openings formed in an exposed proximate end of the mixer element. The gaseous fuel mixes with the intake air, and the mixture of intake air and gaseous fuel flows from the second end of the mixer body to the first end of the mixer body and then to the intake manifold.Type: GrantFiled: August 27, 2012Date of Patent: June 24, 2014Assignee: Cummins Intellectual Property, Inc.Inventors: Jason Czapka, Edward J.
