Patent number: 11746725Abstract: A piston for an internal combustion engine which is coated for enhanced oxidation protection and/or erosion protection is provided. The piston includes a body formed of an iron-based material. The iron-based material is coated with a superalloy and manganese phosphate. The superalloy is preferably NiCrAlY, NiCrAl, NiCr, CoCrAly, and/or CoNiCrAlY. The manganese phosphate can be disposed on the superalloy, but not between the superalloy and the iron-based material. The superalloy preferably has a thickness of 0.1 to 2.0 mm, a porosity of 1% to less than 5%, and a surface roughness of less than 5 microns Ra. Another component for an internal combustion engine which is coated with the superalloy and the manganese phosphate is also provided.Type: GrantFiled: January 17, 2020Date of Patent: September 5, 2023Assignee: Tenneco Inc.Inventors: Warran Boyd Lineton, Gregory Salenbien, Michael Weinenger

Patent number: 10731598Abstract: A vehicle internal combustion piston and method of construction thereof are provided. The piston includes piston body extending along a central longitudinal axis, having an upper combustion wall forming an upper combustion surface and an undercrown surface opposite the upper combustion surface. An annular ring belt region depends from the upper combustion surface, a pair of skirt panels depend from the ring belt region, and a pair of pin bosses depend from the undercrown surface to provide laterally spaced pin bores aligned along a pin bore axis for receipt of a wrist pin. The undercrown surface forms a central undercrown region, and a portion of either an open outer cooling gallery, a sealed outer cooling gallery, or an outer galleryless region. A coating including copper is applied to hot spots along the undercrown surface to mitigate the hot spots provide a more uniform temperature along the undercrown surface during operation.Type: GrantFiled: October 18, 2018Date of Patent: August 4, 2020Assignee: Tenneco Inc.Inventors: Warran Boyd Lineton, Miguel Azevedo, Thomas Egerer, Gregory Salenbien, Neil Ainsworth

Publication number: 20190331222Abstract: A piston formed of steel and/or cast iron for a heavy-duty diesel engine which includes an oil belt for controlling an oil film and thus achieving reduced oil consumption and carbon build-up is provided. The piston includes an uppercrown portion presenting a combustion surface, a ring belt depending from the combustion surface, pin bosses depending from the ring belt, and skirt panels depending from the ring belt and located diametrically opposite one another. The ring belt includes two ring grooves preferentially but accommodates a 3 ring groove version for containing piston rings. The oil belt is located axially below a pin bore on the pin bosses. The oil belt also has a convex shape extending continuously around a circumference of the piston.Type: ApplicationFiled: April 26, 2018Publication date: October 31, 2019Inventors: Miguel Azevedo, Gregory Salenbien

Patent number: 10247132Abstract: A piston for an internal combustion engine and method of construction thereof is provided. The piston has a piston body including an upper part and a lower part. The upper part has an upper combustion surface configured for direct exposure to combustion gases within a cylinder bore with an undercrown surface beneath the upper combustion surface. The body has a ring belt region configured for receipt of at least one piston ring adjacent the upper combustion surface with an annular cooling gallery configured radially inwardly from the ring belt region. The cooling gallery has a floor, wherein the floor has at least one through opening. A coolant medium is disposed in the cooling gallery, and a sealing member is disposed in the at least one through opening to seal off the coolant medium in the coolant gallery.Type: GrantFiled: February 1, 2016Date of Patent: April 2, 2019Assignee: Tenneco Inc.Inventors: Gregory Salenbien, Miguel Azevedo

Patent number: 10125719Abstract: A piston for an internal combustion engine having an improved oil control ring is provided. The piston has a piston body providing an upper combustion surface and an annular outer wall depending therefrom. A ring belt region including a plurality of ring grooves is formed in the annular outer wall. A first compression ring is disposed in one of the ring grooves and the oil control ring is disposed in another of the ring grooves. The oil control ring has generally parallel, planar upper and lower surfaces, with the upper and lower surfaces having an annular groove recessed therein. A through opening can be formed to bring the annular grooves into fluid communication with one another. The annular grooves collect oil scraped from a cylinder wall and return oil to the crank sump and reduce the contact area between the oil control ring and the wall of the ring groove.Type: GrantFiled: October 30, 2015Date of Patent: November 13, 2018Assignee: Tenneco Inc.Inventors: Miguel Azevedo, Gregory Salenbien, Matthew Belford

Patent number: 9494233Abstract: The invention provides a low tension piston ring having a finished outer diameter and negligible tangential tension. The method includes the steps of machining a stock bar to an initial outer diameter slightly greater than the finished outer diameter of the piston ring, finishing the initial outer diameter of the stock bar to a rounded profile having a nominal diameter equal to the finished outer diameter, and machining the stock bar to the preferred cross-section. Dykes-type piston rings can have keystone or semi-keystone shaped cross-sections. The method continues by detaching the piston ring from the stock bar using a parting tool in response to completing all tension inducing operations including the steps recited above. The method continues with the steps of lapping the piston ring to a final longitudinal thickness and cutting the piston ring longitudinally to form a final gap.Type: GrantFiled: January 21, 2016Date of Patent: November 15, 2016Assignee: Federal Mogul CorporationInventors: Gregory Salenbien, Miguel Azevedo, Matthew Belford
