Patent number: 10473059Abstract: A natural gas fueling system supplies methane gas to an engine and includes a filter assembly. The filter assembly includes a gas inlet configured to receive inlet gas and a methane permeable filter configured to separate methane gas and first contaminant gases from the inlet gas. The natural gas fueling system also includes a reformer apparatus configured to convert the first contaminant gases into a reformed gas stream including methane gas. The reformed gas is supplied to the gas inlet and is recirculated through the filter assembly to extract the methane gas from the reformed gas stream.Type: GrantFiled: February 9, 2018Date of Patent: November 12, 2019Assignee: Cummins Inc.Inventors: Corey W. Trobaugh, Daniel A. Norrick, Randy E. Berg, Brian K. Wagner

Patent number: 9404417Abstract: Systems, methods and apparatus for noise attenuation of a generator set are disclosed. The generator set includes an internal combustion engine enclosed within a compartment that substantially isolates the internal combustion from ambient air and a load connected to the internal combustion engine. A heat exchanger is disposed within or coupled to the compartment and is operable to cool air in the compartment without directly exchanging ambient air with compartment air.Type: GrantFiled: November 30, 2012Date of Patent: August 2, 2016Assignee: CUMMINS POWER GENERATION, INC.Inventors: Daniel Norrick, Madhukar Mahishi

Patent number: 9334769Abstract: Generally, an overflow conduit is described in apparatuses, systems, and methods to protect a crankcase oil sump from overfill. The overflow conduit is to be connected to a crankcase oil sump of an engine, and is configured to passively receive oil from the crankcase oil sump to avoid an overfill condition from occurring in the crankcase oil sump. The overflow conduit is configured to deliver excess oil received to a sub-base tank located relatively below the crankcase oil sump, or in particular at or below an oil level in the crankcase oil sump.Type: GrantFiled: January 25, 2013Date of Patent: May 10, 2016Assignee: Cummins Power Generation IP, Inc.Inventors: Daniel A. Norrick, Paul H. Plahn

Patent number: 6892715Abstract: An improved crankcase ventilation system for a vehicle which includes an air compressor to route crankcase gases to the intake manifold for combustion. The primary vehicle components include and aircleaner, a turbocharger compressor positioned downstream from the aircleaner, an optional aftercooler positioned downstream from the turbocharger compressor, and an engine having an intake manifold and a crankcase equipped with a breather port for venting crankcase gases. Crankcase gases are vented through the breather port to the air compressor. Clean air from downstream of the aircleaner but upstream of the turbocharger compressor is drawn into the air compressor as needed to prevent the air compressor from drawing too much crankcase gas and reducing the internal pressure of the crankcase to undesirable levels.Type: GrantFiled: July 3, 2003Date of Patent: May 17, 2005Assignee: Cummins, Inc.Inventor: Daniel A.
