Publication number: 20180119593Abstract: The present disclosure provides a method for operating an exhaust gas aftertreatment device for cleaning an exhaust gas flow of a motor vehicle with an internal combustion engine operated in normal mode with oxygen surplus. An oxygen store arranged downstream of an NOx storage catalyst of the exhaust gas aftertreatment device receives oxygen in normal mode, and during a regeneration mode emits oxygen for converting breakthrough hydrocarbons and/or carbon monoxide. The oxygen store is assigned to a particulate filter and/or an oxidation catalyst of the exhaust gas aftertreatment device. The particulate filter and/or the oxidation catalyst is arranged downstream of the NOx storage catalyst.Type: ApplicationFiled: October 30, 2017Publication date: May 3, 2018Applicant: Ford Global Technologies, LLCInventors: Jan Harmsen, Mario Balenovic

Patent number: 9926820Abstract: An example oil system is provided, including at least one oil chamber forming an oil sump, an oil reservoir, which is arranged separately from the oil chamber, and at least partially arranged at the same geodetic height as the oil chamber, and at least one fluid connection which connects the oil chamber to the oil reservoir. An electric shut-off unit may block the fluid connection of the oil chamber to the oil reservoir in a blocking state and at least partially release the same in a release state. In order to extend oil changing intervals, a number of regeneration operations and an estimate of an instantaneous degree of dilution of oil present in the oil chamber, may be used for activating the electric shut-off unit to connect or block the fluidic connection between the oil chamber and the oil reservoir.Type: GrantFiled: April 22, 2016Date of Patent: March 27, 2018Assignee: Ford Global Technologies, LLCInventors: Hans Guenter Quix, Brendan Patrick Carberry, Mario Balenovic

Publication number: 20160251012Abstract: The present disclosure relates to an operating method for a motor vehicle having a hybrid drivetrain where in a demand check, at least one exhaust-gas after-treatment actual value, which characterizes a current exhaust-gas after-treatment actual state, is compared with an exhaust-gas after-treatment setpoint value, and if, in the event of a deviation of the exhaust-gas after-treatment actual value from the exhaust-gas after-treatment setpoint value, a demand for a measure is detected.

Patent number: 8869753Abstract: An engine and related control system determine an amount of fuel diluting the engine oil in the oil pan. Such information can be used to recommend an oil change and to estimate a fraction of biodiesel in the fuel supplied to the engine. According to one embodiment, actual oil volume in the oil pan is based on a signal from a level sensor in the oil and a theoretical oil volume is determined based on initial oil volume and fuel entering the oil in the oil pan, fuel leaving the oil pan due to evaporation, and oil being consumed in the combustion chamber. Based on the difference between the actual and theoretical oil volumes, a proportion of heavy fuel components or biodiesel can be determined and transmitted to an engine control system.Type: GrantFiled: September 14, 2012Date of Patent: October 28, 2014Assignee: Ford Global Technologies, LLCInventors: Matthew Allen Schneider, Yasser Mohamed sayed Yacoub, Mario Balenovic
