Patent number: 9951744Abstract: An ignition device for an internal combustion engine includes optical focusing lenses, including a center optical focusing lens and satellite optical focusing lens. The center optical focusing lens focuses laser light from a laser generator to a center ignition point in a combustion chamber of a cylinder of the internal combustion engine. The satellite optical focusing lenses focus laser light from the laser generator to satellite ignition points in the combustion chamber of the cylinder of the internal combustion engine. The satellite optical focusing lenses are directionally angled away from the center optical focusing lens. A firing depth of the center ignition point is greater than a firing depth of the at least one satellite ignition point.Type: GrantFiled: May 26, 2016Date of Patent: April 24, 2018Assignees: DENSO International America, Inc., DENSO CORPORATIONInventors: Jeongung Hwang, Nicholas C. Polcyn, Jeremy Koscielny

Patent number: 9932956Abstract: A laser ignition device for an internal combustion engine can include a laser generator, a housing, and a window. The laser generator can emit a pulse of laser light. The housing can be coupled to the internal combustion engine. The housing can have a first end and a second end. The second end can be proximate to a combustion chamber of the internal combustion engine and can define an aperture through which the laser light is permitted to exit the housing into the combustion chamber. The window can be coupled to the second end of the housing and cover the aperture. The window can permit the laser light to pass through the window and into the combustion chamber. The window can have a rounded outer surface.Type: GrantFiled: February 24, 2016Date of Patent: April 3, 2018Assignees: DENSO International America, Inc., DENSO CORPORATIONInventors: Jeongung Hwang, Christopher Thomas, Nicholas C. Polcyn

Patent number: 8912716Abstract: A spark plug for an internal combustion engine includes a spark plug housing. An insulator is concentrically located within the housing and has a distal end extending from an outer surface of the housing. A center electrode extends from a proximal end of the insulator. A ground electrode is secured to the housing and has an electrode tip arranged a distance from the center electrode. A chamber cap fixedly secured to the housing and surrounding both the center and ground electrodes, includes a laminate shell and a plurality of orifices.Type: GrantFiled: March 21, 2011Date of Patent: December 16, 2014Assignee: DENSO International America, Inc.Inventors: Jeongung Hwang, Nicholas C. Polcyn, Christopher Thomas

Patent number: 8350457Abstract: A spark plug includes a housing, a center electrode, a ground electrode, and a pre-chamber cup. The housing is configured to thread into a spark-plug hole in an engine. The center electrode extends axially from a center of the housing. The ground electrode extends radially inward from the housing. The pre-chamber cup is attached to the housing. The housing defines a gas thread cavity that extends radially at least partially through the housing.Type: GrantFiled: March 31, 2011Date of Patent: January 8, 2013Assignee: DENSO International America, Inc.Inventors: Christopher Thomas, Jeongung Hwang, Nicholas C.

Publication number: 20110241521Abstract: A spark plug for an internal combustion engine includes a housing having a distal end, a proximal end, and an outer periphery extending therebetween. A mounting thread formed on the outer periphery at the proximal end of the housing secures the spark plug to the engine. A center electrode fixedly secured along a central axis of the housing has a first end extending outwardly from the proximal end of the housing. A ground electrode secured to the proximal end of the housing has an electrode tip at a first distance from the center electrode. The electrode tip has a central aperture extending through the ground electrode from an upper surface to a lower surface. A protruding edge circumscribes the aperture and extends a second distance from the upper surface of the electrode tip towards the center electrode.Type: ApplicationFiled: March 30, 2010Publication date: October 6, 2011Applicants: DENSO INTERNATIONAL AMERICA, INC., DENSO CORPORATIONInventors: Nicholas C.
