Patent number: 10358990Abstract: Methods are provided for managing forcing function frequency profiles during operation of a multi-cylinder engine. A first stroke mode for a first cylinder is selected and comprises at least a sequential deactive operation of the opening and the closing of a first intake valve and a first exhaust valve during at least two reciprocations of a first reciprocating piston. The first stroke mode is operated on the first cylinder, a second stroke mode is operated on a second cylinder, and a third stroke mode is operated on the remaining cylinders to meet or exceed a required torque output and to form a first aggregate of forcing function frequency profiles that comprises primary forcing function frequency profiles that are less than or approximate in amplitude and less than or approximate in frequency value to one of the respective baseline of primary forcing function frequency profiles.Type: GrantFiled: June 28, 2017Date of Patent: July 23, 2019Assignee: Eaton Intelligent Power LimitedInventor: Dale A.

Patent number: 7980483Abstract: An injector for an injection system is provided, including a first opening, a second opening, an open position and a closed position. The first opening is for spraying the fluid out of the injector, and the second opening is for allowing the fluid to exit the injector. When the injector is in the open position, the injector sprays the fluid from the first opening and the flow of the fluid to the second opening is substantially blocked. When the injector is in the closed position the injector allows the fluid to exit the injector from the second opening. The injector substantially blocks the spray of the fluid from the first opening when the injector is in the closed position.Type: GrantFiled: October 13, 2008Date of Patent: July 19, 2011Assignee: Eaton CorporationInventor: Dale A.
