Patent number: 8868283Abstract: An oil-life monitoring system includes an engine revolution counter configured to provide an output corresponding to the rotation of a component of an engine, and a controller in communication with the engine revolution counter. The controller is configured to determine the composition/properties of a fuel being combusted by the engine, and select a fuel quality penalty factor from a table, with the fuel quality penalty factor corresponding to the determined composition/properties of the fuel. Additionally, the controller is configured to compute an adjusted revolution count by multiplying the rotations of the component of the engine by the fuel quality penalty factor, and aggregate the adjusted revolution count.Type: GrantFiled: May 3, 2012Date of Patent: October 21, 2014Assignee: GM Global Technology Operations LLCInventors: Yunpeng Geng, Andrew E. Buczynsky

Patent number: 8527127Abstract: A method and system of determining a maximum oil change limit for an engine considering the engine operating environment and location is provided. An engine location indicator is generated in response to a trigger, using a locating device in communication with a controller. The locating device may include a global positioning system (GPS) receiver. The engine may be an internal combustion engine on a vehicle configured as one of a hybrid vehicle and an extended range electric vehicle. The trigger may be one of a calendar time, a key-on event, an oil change event, and a signal provided by the controller. The controller may generate the maximum oil change limit of the engine using one or more oil change indices, each defined by the engine location and/or time in location. The maximum oil change limit and/or an oil change limit alert may be provided as an output of the controller.Type: GrantFiled: February 10, 2011Date of Patent: September 3, 2013Assignee: GM Global Technology Operations LLCInventors: Robert Lionel Jacques, Matthew J. Snider, Andrew E. Buczynsky

Patent number: 8152866Abstract: In various aspects, a synthetic diesel fuel composition is provided that comprises at least three C10-C18 hydrocarbon compounds selected from the group consisting of decane, butylcyclohexane, hexylbenzene, hexylcyclohexane, octylbenzene, octylcyclohexane, decylbenzene, decylcyclohexane, dodecylbenzene, and dodecylcyclohexane. The synthetic diesel fuel composition also comprises at least one aromatic hydrocarbon compound at greater than or equal to about 10 vol. % of the total composition. Such synthetic diesel fuel compositions have a cetane number of greater than 40, a freeze point of less than or equal to about ?20° C. (about ?4° F.), and a density of greater than or equal to about 0.81 g/ml (about 6.8 lb/gal) and may be synthesized from biomass or other alternative fuel sources.Type: GrantFiled: May 13, 2009Date of Patent: April 10, 2012Inventor: Andrew E.

Patent number: 7878182Abstract: An evaporative emissions system may include a first passage selectively providing fluid communication between a fuel vapor region of a vehicle fuel reservoir and an engine air intake system, a second passage in fluid communication with the fuel vapor region and ambient air, and a filter assembly. The filter assembly may be impermeable to at least one of oxygen and hydrocarbons and may be located in the second passage between the fuel vapor region and ambient air. The filter assembly may prevent the at least one of oxygen and hydrocarbons from traveling between the fuel vapor region and ambient air.Type: GrantFiled: May 1, 2009Date of Patent: February 1, 2011Assignee: GM Global Technology Operations LLCInventors: Pui-Kei Yuen, Andrew E.
