Abstract: An active regeneration method for a gasoline particulate filter includes determining if a particulate filter soot load level is greater than a predetermined soot load level threshold and, if so, determining if the particulate filter's temperature is greater than a predetermined burn off temperature threshold. A particulate filter heating phase is initiated when the particulate filter's temperature is not greater than a predetermined burn off temperature threshold and a soot burning phase is started when the particulate filter's temperature is greater than a predetermined burn off temperature threshold.

IPC: F02D41/02
Abstract: A method and system for regenerating a gasoline particle filter of an internal combustion engine is provided in which a value (Q) for a quantity of soot collected inside of the gasoline particle filter and a value (T) for a temperature of the gasoline particle filter are determined. The internal combustion engine is operated in a lean mode when the value (Q) for the soot quantity is greater than a first threshold, and the value (T) for the temperature of the gasoline particle filter is greater than a threshold.

Abstract: A method and system controls a regeneration of a particle filter of an internal combustion engine. A first value is measured for the oxygen content in exhaust gas upstream from the particle filter. A second value is measured for the oxygen content in exhaust gas downstream from the particle filter. The particle filter is determined to be free of soot when the second value for the oxygen content is equal to the first value for the oxygen content.

Abstract: Methods and systems are provided for generating a predictive tachometer profile at a tachometer of a vehicle. An engine speed offset can be generated based on a commended engine torque and engine inertia. A predictive tachometer profile displayed at the tachometer can then be generated based on the engine speed offset and a previous predictive tachometer profile.

Abstract: The method determines whether soot loading of a gas particulate filter (GPF) requires regeneration. If it does, the temperature of the GPF is read to determine whether it is sufficiently high to achieve particulate (soot) burning. If it is not, an engine control module is commanded to adjust variables such as spark timing, fuel injection timing and valve timing. If the temperature of the particulate filter is sufficiently high that regeneration can occur, other variables may be adjusted such as leaning the air/fuel mixture, retarding the spark timing, the fuel injection and valve timing. Because the latter adjustments may limit or reduce either engine speed or power, messages in a message center are provided indicating, first, that the driver should continue driving for GPF regeneration and, subsequently, under certain conditions, that the engine power has been reduced. Operation of the motor vehicle proceeds until, based upon sensed conditions or pre-determined experimental or empirical data, the filter has been regenerated.
