Patent number: 8776585Abstract: Systems and methods are provided for monitoring reverse flow of fuel vapors and/or air through a vehicle fuel vapor recovery system, the fuel vapor recovery system coupled to an engine intake of a boosted internal combustion engine. One example method comprises, intermittently adjusting a restriction in the fuel vapor recovery system during boosted conditions, and indicating degradation based on one or more of a change in a pressure value, or based on a change in flow in the fuel vapor recovery system.Type: GrantFiled: November 19, 2012Date of Patent: July 15, 2014Assignee: Ford Global Technologies, LLCInventors: Ross Dykstra Pursifull, Allan J. Lippa, John D. Russell, Gopichandra Surnilla, Joseph Norman Ulrey

Patent number: 8495874Abstract: A method for providing intake air to an engine in a vehicle comprises delivering compressed fresh air and EGR to the engine via first and second throttle valves coupled to an intake manifold of the engine. During a higher engine-load condition, an EGR exhaust flow is cooled in a heat exchanger and the cooled EGR exhaust flow is admitting to the intake manifold. During a lower engine-load condition, fresh air is warmed in the heat exchanger, and the warmed fresh air is admitted to the intake manifold.Type: GrantFiled: November 14, 2011Date of Patent: July 30, 2013Assignee: Ford Global Technologies, LLCInventors: Allan J. Lippa, Ross Dykstra Pursifull, Allan J. Kotwicki

Patent number: 8335632Abstract: A fuel delivery system for an internal combustion engine and a method of operating the fuel delivery system is described. As one example, the method includes delivering a first fuel blend from a first fuel tank to the engine; delivering a second fuel blend from a second fuel tank to the engine, the proportion of said second fuel blend delivered to the engine to said first fuel blend delivered to the engine being related to the desired engine output; transferring said first fuel blend from said first fuel tank to said second fuel tank to prevent an amount of said first fuel blend and said second fuel blend in said second fuel tank from falling below a predetermined level; and boosting air delivered to the engine, the amount of boosting being related to latent heat of vaporization of said second fuel blend delivered to the engine.Type: GrantFiled: June 24, 2011Date of Patent: December 18, 2012Assignee: Ford Global Technologies, LLCInventors: Allan J.

Patent number: 7974765Abstract: A fuel delivery approach for an engine includes delivering a first fuel blend from a first, lower alcohol fuel tank to a port injector; delivering a second, higher alcohol, fuel to a direct injector, and transferring the first fuel from the first tank to the second tank so that the first tank is emptied before the second. In this way, at least some fuel is available for direct injection even when the higher alcohol fuel is exhausted prior to the lower alcohol fuel. Thus, it is possible to at least obtain charge cooling benefits of direct injection, and therefore the engine may be operated with a greater amount of boost.Type: GrantFiled: September 23, 2010Date of Patent: July 5, 2011Assignee: Ford Global Technologies, LLCInventors: Allan J.
