Patent number: 9915180Abstract: A novel latch seat for a switching rocker arm assembly used in variable valve actuation (VVA) systems for internal combustion engines. The seat is formed interactively in the assembled switching rocker arm using a novel fixture and press. The press interactively creates a curved dimple of the correct curvature, position and depth while measuring several lash dimensions. Since the latch seat is formed on the assembled rocker arm assembly, the latch seat depth is designed to account for the inaccuracies in the rocker arm assembly parts which create lash. Therefore all of the parts may be made with less precision since the latch seat is sized to compensate for the inaccuracies of all of the parts. The rocker arm assembly parts now may be manufactured to less stringent standards, but result in a rocker arm assembly with same accuracy of rocker arm assemblies manufactured to previous standards.Type: GrantFiled: December 28, 2015Date of Patent: March 13, 2018Assignee: EATON CORPORATIONInventors: Anthony L.

Patent number: 9915189Abstract: The disclosure describes multipoint ignition systems for an engine and methods of operation of the same. The systems and methods can include an engine, including an engine block having at least one cylinder bore, a piston having a piston crown facing a flame deck surface such that a combustion main chamber is defined within a cylinder bore and located between the piston crown and the flame deck surface, the piston crown further including a piston bowl having a generally concave shape, and a combustion pre-chamber having a nozzle tip disposed in fluid communication with the combustion main chamber, the nozzle tip having at least one nozzle opening configured to inject a fuel jet into the combustion main chamber, wherein the piston includes a piston wall located around a circumference of the piston bowl, the piston wall including at least one cavity.Type: GrantFiled: November 19, 2015Date of Patent: March 13, 2018Assignee: Caterpillar Inc.Inventor: Jaswinder Singh

Patent number: 9915190Abstract: A ducted combustion system is disclosed. The ducted combustion system may include a combustion chamber, which is defined as an enclosure bound at a first end by a flame deck surface of a cylinder head of an internal combustion engine and bound at a second end by a piston top surface of a piston disposed within the internal combustion engine. The system may further include a fuel injector, having at least one orifice, injecting fuel into the combustion chamber as at least one fuel jet. The system may further include at least one Venturi duct disposed within the combustion chamber between the flame deck surface and the piston top surface, the at least one Venturi duct being disposed such that each of the at least one fuel jet, at least partially, enters the at least one Venturi duct structure upon being injected into the combustion chamber.Type: GrantFiled: July 13, 2015Date of Patent: March 13, 2018Assignee: Caterpillar, Inc.Inventor: Chad Koci

Patent number: 9915191Abstract: An intake manifold is provided that controls swirl on entry to a combustion chamber. Each intake manifold includes a fin or rib portion positioned to reduce or eliminate swirl induced by the configuration of the intake manifold, particularly when used in a large engine having a left bank and a right bank of combustion chambers. By controlling swirl induced by the intake manifold, swirl consistency is improved between engine cylinders and between the left bank and the right bank, improving the consistency of power output and reducing emissions, particularly particulate emissions, also called smoke.Type: GrantFiled: February 9, 2017Date of Patent: March 13, 2018Assignee: CUMMINS INC.Inventors: Paul Douglas Free, Jason Robert Griffin, Alex Edward Priestley, Stephen Sunadh Gidla, Peter Vinson Woon, Joseph Scot Roederer

Patent number: 9915192Abstract: A power conversion device in the form of a compressor drive constitutes a three channel power sharing transmission which allows power input and/or output from shafts on two of the channels along with hydraulic, electric or potentially pneumatic power input and/or output from the third channel. Varying the input and/or output of hydraulic, electric or pneumatic flow provides a continuously variable transmission function. Several embodiments of the power conversion device are described to drive a supercharger for an internal combustion engine providing a variable ratio coupling allowing effective use of a centrifugal type compressor across a broad range of operational engine speeds.Type: GrantFiled: August 4, 2015Date of Patent: March 13, 2018Inventor: Jeffrey J.

Patent number: 9915193Abstract: A method for operating an internal combustion engine (10) that has at least one cylinder row (11a, 11b) with first and second exhaust-gas turbochargers (13a, 13b; 14a, 14b). Charge air is provided by the first exhaust-gas turbocharger (13a, 13b) in single-charger operation, but is provided by the first and second exhaust-gas turbocharger (13a, 13b; 14a, 14b) in two-charger operation. To switch from single-charger to two-charger operation above a load threshold value of the internal combustion engine (10), when a speed of the internal combustion engine (10) reaches or overshoots a threshold value, a charge pressure is increased to build up a torque reserve and a charge pressure reserve and to maintain a driver demand torque. When the charge pressure reaches or overshoots a threshold value, a switch is made from single-charger operation to two-charger operation, and subsequently, the torque reserve and the charge pressure reserve are eliminated.Type: GrantFiled: November 9, 2015Date of Patent: March 13, 2018Assignee: DR. ING. H.C.F. PORSCHE AKTIENGESELLSCHAFTInventors: Andre Casal Kulzer, Thorben Walder, Ludwig Theilemann, Michael Reinhardt, Michael Ebert

Patent number: 9915194Abstract: Methods and systems are provided for operating an engine with variable displacement engine (VDE) operation coupled to a twin scroll turbocharger. One method comprises directing exhaust from a first outer cylinder and a first inner cylinder of four cylinders to a first scroll of the twin scroll turbocharger, directing exhaust from a second outer cylinder and a second inner cylinder of the four cylinders to a second scroll of the twin scroll turbocharger, and during a first condition, firing all four cylinders with uneven firing.Type: GrantFiled: June 12, 2017Date of Patent: March 13, 2018Assignee: Ford Global Technologies, LLCInventors: Brad Alan Boyer, Gregory Patrick McConville, Kim Hwe Ku, James Douglas Ervin
