    摘要: A method of controlling an engine of a vehicle having a particulate filter and operable in an air restriction mode wherein air inflow to an air intake throttle is restricted includes determining if the engine is operating in the air restriction mode, sensing a position of an accelerator pedal, and sensing a speed of the vehicle. The method further includes removing the restriction to the air intake throttle when the engine is operating in the air restriction mode, one of a change in position of the accelerator pedal over a period of time is greater than a pre-defined pedal acceleration rate or the position of the accelerator pedal is equal to a pre-defined pedal limit, and the speed of the vehicle is less than a pre-defined speed limit.

    摘要: A method of operating an engine having an after-treatment system that treats exhaust gas from the engine with an oxidation catalyst includes adjusting the operation of the engine to increase the temperature of the exhaust gas, continuously sensing a cylinder pressure with a pressure sensor disposed at at least one cylinder of the engine to identify a unstable combustion event, i.e., an engine misfire, and adjusting the operation of the engine to prevent a future unstable combustion event when the unstable combustion event is detected.

    摘要: A method of defining a target regeneration temperature setpoint for exhaust gas upstream of a particulate filter of an exhaust gas treatment system includes as defining the regeneration temperature setpoint to include an idle temperature setpoint when the current vehicle operating mode is classified as an idle mode, and defining the regeneration temperature setpoint to include a driving temperature setpoint when the current vehicle operating mode is classified as a driving mode. The idle temperature setpoint and the driving temperature setpoint are derived individually of and separately from each other, and are based on different criteria.

    摘要: A method of controlling an exhaust gas treatment system includes measuring a quantity of fuel used by the vehicle during a defined time period of a regeneration event, and estimating a quantity of particulate matter being burnt from a particulate filter during the defined time period to define a particulate matter burn rate. The quantity of fuel used is compared with the calculated particulate matter burn rate to define a regeneration fuel efficiency ratio. The regeneration fuel efficiency ratio is compared to a minimum regeneration fuel efficiency rate to determine if the regeneration event is an efficient use of fuel or is not an efficient use of fuel. The regeneration event is stopped prior to an estimated completion of the regeneration event when the comparison of the regeneration fuel efficiency ratio to the minimum regeneration fuel efficiency rate indicates that the regeneration event is not an efficient use of fuel.
