Patent number: 11598237Abstract: A diesel engine system includes an engine, an exhaust system connected to the engine, and a water-fuel separator. The exhaust system has an aftertreatment device, an exhaust pipe upstream of the aftertreatment device, and a fuel injector connected to the exhaust pipe. The water-fuel separator has a filter configured to separate water from fuel and a reservoir configured to store the separated water. The reservoir is in fluid communication with the fuel injector.Type: GrantFiled: March 15, 2021Date of Patent: March 7, 2023Assignee: Ford Global Technologies, LLCInventors: Brien Lloyd Fulton, Carlos Armesto

Patent number: 11130083Abstract: Embodiments for a fuel filter are provided. In one example, a diesel fuel filter comprises a header having an inlet port, an outlet port, a recirculation inlet port, and a recirculation outlet port; and a filter body made having different material than the header, the filter body coupled with the header and housing a filter membrane. In this way, electrostatic discharge may be reduced.Type: GrantFiled: October 28, 2015Date of Patent: September 28, 2021Assignee: Ford Global Technologies, LLCInventors: Paul Chretien, Carlos Armesto, Guido Barta

Patent number: 9366206Abstract: A fuel-air separator includes a chamber with an interior side-wall surface and adjacent interior top and bottom surfaces. An inlet of the fuel-air separator opens to the interior side-wall surface to admit fuel and air and to cause the fuel and air to flow helically down and along the interior side-wall surface. A diptube opens to the bottom surface and extends along an axis of the interior side-wall surface to a fuel outlet, while the separated air is released to the atmosphere.Type: GrantFiled: December 17, 2012Date of Patent: June 14, 2016Assignee: Ford Global Technologies, LLCInventors: Eric Myers, Yi Zhang, Syed K. Ali, Mike Dong, Carlos Armesto
