Publication number: 20240116108Abstract: A system for an engine comprises a component manufactured via additive manufacturing. The component includes a first material with a first contraction rate. An insert is disposed in the component and comprises a second material with a second contraction rate that is lower than the first contraction rate. When the component and the insert are exposed to a temperature suitable for sintering, the component contracts around the insert, thereby coupling the insert and the component.Type: ApplicationFiled: February 18, 2022Publication date: April 11, 2024Applicant: CUMMINS INC.Inventor: Howard S.

Patent number: 8839517Abstract: A catalytic device and method for forming a catalytic device are described. The devices and methods described can be used for emissions systems in heavy duty diesel engines. In particular, a method of spin forming a catalytic device generally includes disposing a mat about an outer surface of a catalyst substrate and inserting the catalyst substrate and mat inside a shell. The mat is between the shell and the catalyst substrate. The shell, catalyst substrate, and mat can be spin formed into at least a generally elliptical shape but generally other than a circle shape.Type: GrantFiled: April 29, 2013Date of Patent: September 23, 2014Assignee: Cummings Filtration IP, Inc.Inventors: Bryan E. Blackwell, Eric L. Reeck, Howard S. Savage

Patent number: 6253736Abstract: An injector is provided which includes a nozzle valve element, a control volume, and an injection control valve for controlling fuel flow from the control volume so as to control nozzle valve movement. Importantly, the injector includes a nozzle valve lift detecting device for detecting nozzle valve lift and providing a nozzle valve element lift feedback signal. In addition, an injection control valve member movement detecting device may be provided for detecting movement of the injection control valve member into open and/or closed positions and generating a control valve member position feedback signal. One or both of the feedback signals may be used for adjusting the timing and/or rate of opening of the injection control valve thereby controlling the timing and/or rate of opening of the nozzle valve element to control the timing and/or rate of fuel injection of subsequent injection events.Type: GrantFiled: August 10, 1999Date of Patent: July 3, 2001Assignee: Cummins Engine Company, Inc.Inventors: John D. Crofts, Mark S. Cavanagh, Howard S. Savage

Patent number: 5117065Abstract: A method of joining shielding materials used for minimizing passage of electromagnetic and radio frequency energy through the walls of an enclosure, comprising the steps of securing a metallic backing plate to one wall of the enclosure, positioning an end portion of a first sheet of shielding material to the backing plate, then positioning an end portion of second sheet of shielding material atop the end portion of the first sheet of shielding material, and then applying a vibrating tool to the overlapped end portions of the first and second sheets of shielding material to metallurgically bond the facing surfaces of the overlapped shielding materials. A joint structure resulting from practice of the method is also disclosed.Type: GrantFiled: June 15, 1990Date of Patent: May 26, 1992Inventors: Howard S. Savage, Paul H. Nielsen
