Cheryl Klepser has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • System and method for on-board waste heat recovery
    Patent number: 8920770
    Abstract: A technique is described including receiving a hydrocarbon stream, and heating the hydrocarbon stream with an exhaust steam from an internal combustion engine. This technique may include reacting the hydrocarbon stream catalytically to produce hydrogen and a modified hydrocarbon stream having a lower saturation state than the hydrocarbon stream, recovering energy from the hydrogen stream, and/or providing the modified hydrocarbon stream to a fuel supply for the internal combustion engine.
    Type: Grant
    Filed: April 11, 2013
    Date of Patent: December 30, 2014
    Assignee: Cummins Inc.
    Inventors: Wayne Goodman, Aleksey Yezerets, Neal W. Currier, Cheryl Klepser

  • Connecting rod with profiled bore for increased load capability
    Patent number: 7240584
    Abstract: An engine cylinder piston connecting rod subassembly, for use in an engine, includes a piston (53), a piston pin (52) and a connecting rod (51). The connecting rod has a piston end portion with a piston pin bore (62). The piston pin is inserted through the piston pin bore and oppositely disposed portions of the piston, for securing the piston and the connecting rod together. Opposite ends of the piston pin bore are machined or profiled with relief portions (60, 61), to allow for piston pin deflection and thereby maximize the load carrying capacity, by providing a greater area of contact. The relief portions can be a curved surface (65) machined as part of the bore, or a plurality of end-to-end angled frustoconical surfaces (66a, 66b, 66c). The relief portions are shaped to correspond to the shape of the corresponding piston pin when under load during normal engine operation.
