Patent number: 10786767Abstract: A filter apparatus is described that has a torque limiting device, which may be a clutch mechanism, and which provides a protective function for a filter, so as to protect a filter from being over tightened and to thereby prevent damage to filter components. The clutch mechanism can also eliminate or reduce the need for torque measurement of certain filter components. The clutch mechanism can be located on one of the fluid filter, a filter head which engages the fluid filter, or a combination of both the fluid filter and the filter head.Type: GrantFiled: March 11, 2016Date of Patent: September 29, 2020Assignee: CUMMINS FILTRATION IP, INC.Inventors: Kurt M. A. Badeau, Travis E. Goodlund, Bryan J. Benz, Bryan P. Steffen, Ismail C. Bagci, Aaron M. Wells, Rahul B. Kallurwar, James L. Eickhoff, Chirag D. Parikh, Gregory W. Hoverson, Kevin C. South, Scott G.

Patent number: 10145343Abstract: A timing-based method for regenerating a DOC included in an aftertreatment system fluidly coupled to a dual-fuel engine comprises performing at least one of the following: a temperature of the DOC is varied while flowing a mixed exhaust gas, which comprises a mixture of a diesel-only exhaust gas and a natural gas exhaust gas, generated by the dual-fuel engine through the DOC; alternately the method includes flowing (a) the mixed exhaust gas generated by the dual-fuel engine and (b) a diesel-only exhaust gas generated by the dual-fuel engine through the DOC.Type: GrantFiled: May 13, 2015Date of Patent: December 4, 2018Assignee: CUMMINS EMISSION SOLUTIONS, INC.Inventors: Yi Liu, Justin Kruer, Rahul B. Kallurwar, Arvind V. Harinath, Zheng Liu

Patent number: 10031098Abstract: A water sensor for a fuel filtration apparatus includes a main body with at least one electrical contact disposed proximate the first end of the main body. The electrical contact(s) is operatively connectable to an electronic control unit. Multiple sensor contacts are disposed proximate a second end of the main body. The sensor contacts are configured to detect multiple water levels and provide an output on each water level detected. The electrical contact is configured to send the output to an electronic control unit. The water level information provided by the water sensor can be tracked by a control device to determine if the fill rate of water meets an alarm value.Type: GrantFiled: August 8, 2016Date of Patent: July 24, 2018Assignee: CUMMINS FILTRATION IP, INC.Inventors: Mark T. Wieczorek, Dean H. Dringenburg, Rahul B. Kallurwar

Patent number: 9010717Abstract: A mounting assembly is described that has an interface designed to increase the stress margin of at least the module side of the assembly, for example in a liquid filtration module, and to increase ease of assembling its mounting components. The interface reduces the failure of the mounting assembly at least on the module side, so that if failure of the mounting assembly occurs, such an occurrence is less likely to be at the interface and on the module side, thereby reducing the need to replace more complex and expensive components that may be on the module side. Generally, the mounting assembly includes a mounting interface and a mounting bracket connectable to the mounting interface. A retention component is configured to maintain connection of the mounting interface to the mounting bracket.Type: GrantFiled: April 11, 2014Date of Patent: April 21, 2015Assignee: Cummins Filtration IP, Inc.Inventors: Rahul B. Kallurwar, Kevin C. South, Charles W. Hawkins, Ismail C. Bagci, Philip S. Hall
