Patent number: 9845780Abstract: Methods and systems are provided for direct fuel injection. In one example, a fuel injector system includes a needle, a plurality of tangential fins coupled to a nozzle end of the needle, an actuator coupled to the needle, and a controller storing non-transitory instructions that when executed cause the controller to, responsive to a command to inject fuel, activate the actuator to push the needle in a downward direction by an amount based on one or more operating parameters. In this way, the fuel injector may inject fuel with a cone shaped spray pattern, reducing the spray penetration of the injected fuel.Type: GrantFiled: November 4, 2015Date of Patent: December 19, 2017Assignee: Ford Global Technologies, LLCInventor: Xiaogang Zhang

Patent number: 9840994Abstract: Methods and systems are provided for direct fuel injection, wherein a fuel injector comprises an injector needle coupled to a frustum shaped nozzle. During a fuel injection event, the injector needle may be moved outward to create an annulus nozzle. In this way, the fuel injector may inject fuel with a cone shaped spray pattern, reducing the spray penetration of the injected fuel.Type: GrantFiled: November 4, 2015Date of Patent: December 12, 2017Assignee: Ford Global Technologies, LLCInventor: Xiaogang Zhang

Patent number: 9797293Abstract: An engine has a cylinder block with a deck face and at least one cylinder liner with a cylinder axis. The block has a first fluid jacket about the liner, a second fluid jacket about the liner, and a third fluid jacket about the liner. The first, second, and third fluid jackets are fluidly independent from one another and spaced apart from one another along the cylinder axis. A method for forming the engine includes using an insert to provide each of the fluid jackets. The insert has a lost core material surrounded by a metal shell.Type: GrantFiled: July 30, 2015Date of Patent: October 24, 2017Assignee: Ford Global Technologies, LLCInventors: Clifford E. Maki, Antony George Schepak

Patent number: 9689288Abstract: An engine assembly includes an oil pan including an oil pan body defining a cavity. The oil pan body includes a dividing wall separating the cavity into a first compartment and a second compartment. The engine assembly further includes a drip tray coupled to the oil pan body. The drip tray is disposed over the second compartment and can direct oil to the first compartment where the oil is warmed up initially in order to minimize the time it takes to heat the oil when the internal combustion engine is warming up. The engine assembly further includes an oil scraper coupled to the oil pan body. The oil scraper is disposed over the drip tray and can scrape oil from a crankshaft.Type: GrantFiled: July 31, 2015Date of Patent: June 27, 2017Assignee: GM Global Technology Operations LLCInventor: Akram R.
