Patent number: 11454147Abstract: Apparatuses, systems and methods are disclosed including an internal combustion engine. The internal combustion engine can include an engine block defining a combustion cylinder and a crankcase, a piston moveable within the combustion cylinder; a cylinder head coupled to the engine block adjacent to and in fluid communication with the combustion cylinder, and a purge system. The purge system can be in fluid communication with the crankcase. The purge system can supply air to the crankcase and to the cylinder head. The purge system can comprise a valve cover coupled to the cylinder head, a breather coupled to the valve cover, and a fumes disposal line coupled with the breather. The fumes disposal line can transport fumes from the breather and away from the cylinder head.Type: GrantFiled: September 21, 2020Date of Patent: September 27, 2022Assignee: Caterpillar Inc.Inventors: Nicholas Edwin Wainscott, Kyle Robert Brewer, Rodney Allen Lawrence, Scott Byron Fiveland, Yongxian Gu

Publication number: 20160237942Abstract: A fuel control system for an engine is provided. The fuel control system includes a first sensor configured to generate a signal indicative of a pressure within a cylinder of the engine, a second sensor configured to generate a signal indicative of an amount of Nitrous Oxide (NOx), a fuel reformer, an Air Fuel Ratio (AFR) unit, and a controller. The controller is configured to receive the signals indicative of the pressure and the amount of NOx. The controller is configured to determine a Coefficient of Variation (COV) of Indicated Mean Effective Pressure (IMEP) and compare the COV of IMEP and the amount of NOx with a threshold combustion stability and a threshold amount of NOx respectively. The controller is further configured to regulate at least one of the fuel reformer and the AFR unit to control at least one of the combustion stability and the amount of NOx.Type: ApplicationFiled: April 25, 2016Publication date: August 18, 2016Applicant: Caterpillar Inc.Inventors: Scott Byron Fiveland, Andrew Loetz, Michael Flory, Joel Hiltner

Patent number: 7849692Abstract: A segmented heat exchanger system for transferring heat energy from an exhaust fluid to a working fluid. The heat exchanger system may include a first heat exchanger for receiving incoming working fluid and the exhaust fluid. The working fluid and exhaust fluid may travel through at least a portion of the first heat exchanger in a parallel flow configuration. In addition, the heat exchanger system may include a second heat exchanger for receiving working fluid from the first heat exchanger and exhaust fluid from a third heat exchanger. The working fluid and exhaust fluid may travel through at least a portion of the second heat exchanger in a counter flow configuration. Furthermore, the heat exchanger system may include a third heat exchanger for receiving working fluid from the second heat exchanger and exhaust fluid from the first heat exchanger. The working fluid and exhaust fluid may travel through at least a portion of the third heat exchanger in a parallel flow configuration.Type: GrantFiled: July 31, 2006Date of Patent: December 14, 2010Assignee: Caterpillar IncInventors: Darryl Dean Baldwin, Martin Leo Willi, Scott Byron Fiveland, Kristine Ann Timmons

Publication number: 20090320814Abstract: A system is disclosed for controlling a combustion engine. The system includes a measurement apparatus disposed external to a combustion chamber of the engine. A device is configured to selectively direct an amount of air and fuel to the measurement apparatus. An ignition source is configured to ignite the air and fuel to produce a flame propagating within the measurement apparatus. A sensor is configured to measure at least one parameter associated with the flame propagating within the measurement apparatus. A controller is configured to determine a flame speed within the measurement apparatus based on the at least one measured parameter, and to control an operating flame speed in the engine by managing an air/fuel ratio of the engine based on the determined flame speed.Type: ApplicationFiled: June 27, 2008Publication date: December 31, 2009Inventors: Scott Byron Fiveland, Martin Leo Willi, David Todd Montgomery
