Publication number: 20240141842Abstract: A method for controlling a dual fuel engine system includes determining a gas flow target for an internal combustion engine of the dual fuel engine system, where the gas flow target is based on a gas power target of the internal combustion engine, a thermal efficiency estimate of the internal combustion engine, and a lower heating value (LHV) within the internal combustion engine. The method also includes adjusting the gas flow target based on at least one of a measured gas temperature or a measured gas injector pressure and determining at least one base gas injector command based on the adjusted gas flow target, a gas substitution rate estimate, and a gas substitution rate target. The method further includes determining, based on the at least one base gas injector command, a gas injector command for at least one engine bank.Type: ApplicationFiled: January 2, 2024Publication date: May 2, 2024Applicant: Cummins Power Generation Inc.Inventors: Travis Alva Anderson, Axel O. zur Loye, Mark A. Rosswurm, Paul Daniel Borisuk, Shashank Bishnoi, Matthew W. Isaacs, Jason A. Gore, Atin Tandon, Jamie Robert John Sleigh

Publication number: 20240133199Abstract: A genset enclosure includes a skid platform, a plurality of gusset members, a plurality of roof supports, and a first and second plurality of sidewall panels. The gusset members are spaced along an outer perimeter of the skid platform and are coupled to the skid platform using fasteners. The gusset members are arranged in opposed pairs positioned on opposite lateral ends of the skid platform. Each gusset member defines a first portion extending upwardly from the skid platform normal to an upper surface of the skid platform and a second portion disposed at an upper end of the first portion and extending normal to the first portion and toward a centerline of the skid platform. The gusset members support the plurality of roof supports and the first and second plurality of sidewall panels to form an enclosed volume.Type: ApplicationFiled: December 29, 2023Publication date: April 25, 2024Applicant: Cummins Power Generation Inc.Inventors: Shashikant Ramdas More, Atin Tandon, Abdullah Caner Demirdogen

Publication number: 20240084746Abstract: A method for controlling a dual fuel engine system includes determining a friction power loss amount of an internal combustion engine of the dual fuel engine system, where the friction power loss amount is based on an engine speed of the internal combustion engine and a friction torque estimate. The method also includes determining an accessory power loss amount of a power of the internal combustion engine, where the accessory power loss amount is based on the engine speed and an accessory torque estimate. The method further includes estimating a net engine power amount based on the accessory power loss amount and a brake power amount of the internal combustion engine, estimating an indicated diesel power, and estimating, based on the estimated net engine power, a first indicated engine power and a first gas power.Type: ApplicationFiled: September 14, 2022Publication date: March 14, 2024Inventors: Travis Alva Anderson, Axel O. zur Loye, Mark A.

Publication number: 20240084745Abstract: A method for controlling a dual fuel engine system includes estimating a total indicated engine load, where the total indicated engine load is based on a sum of a measured engine power and a power loss estimate. The method further includes determining a total fueling amount based on an engine speed and the total indicated engine load, where the total fueling amount includes a gas fueling amount and a diesel fueling amount. The method also includes controlling the dual fuel engine system using the total fueling amount.Type: ApplicationFiled: September 14, 2022Publication date: March 14, 2024Inventors: Travis Alva Anderson, Axel O. zur Loye, Mark A.

Publication number: 20230141599Abstract: Systems, apparatuses, and methods for monitoring a catalyst health parameter are provided. A system includes one or more processing circuits having one or more memory devices coupled to one or more processors. The one or more memory devices store instructions that, when executed by the one or more processors, cause the one or more processors to: receive information indicative of at least one of a temperature of exhaust gas entering the aftertreatment system, a time at idle, or a mass flow of exhaust gas; determine a catalyst health management criteria based on the information; determine a catalyst health indicator based on the catalyst health management criteria being met; compare the determined catalyst health indicator to a predetermined health threshold criteria; and provide a notification based on the determined catalyst health indicator being less than the predetermined health threshold criteria.Type: ApplicationFiled: January 13, 2023Publication date: May 11, 2023Applicant: Cummins Inc.Inventors: Robert C. Borregard, Hasan Mohammed, Atin Tandon, Daniel J. Robinson, Matthew W. Isaacs, Benjamin Goldberger, Arturo Mendoza-Pinon, Douglas Carnecki, Frank Ruggiero, David L. Hirt
