20130239550 | FLEXIBLE REGENERATION TIME OF DIESEL PARTICULATE FILTER BASED ON FUEL EFFICIENCY - 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. | 09-19-2013 |

The idle temperature setpoint and the driving temperature setpoint are derived individually of and separately from each other, and are based on different criteria. | 09-19-2013 |
20130291520 | METHOD OF ESTIMATING A VARIATION OF A QUANTITY OF SOOT ACCUMULATED IN A DIESEL PARTICULATE FILTER - A method of estimating a variation of a quantity of soot accumulated in a diesel particulate filter coupled to an internal combustion engine is provided. The method includes a passive-regeneration check for checking whether a passive regeneration of the diesel particulate filter is occurring and, if this check yields that a passive regeneration is actually occurring, the method includes determining an initial quantity of soot that was accumulated in the diesel particulate filter when the passive regeneration began and determining a rough variation of the quantity of soot accumulated in the diesel particulate filter. An engine speed and an engine load are determined and, using the engine speed, the engine load, and the initial quantity of soot, a correction is determined. The variation of the quantity of soot accumulated in the diesel particulate filter is calculated as a function of the rough variation and the correction. | 11-07-2013 |
20140283502 | METHOD OF CONTROLLING AN EXHAUST GAS TEMPERATURE OF AN INTERNAL COMBUSTION ENGINE - A method of controlling an exhaust gas temperature at a particulate filter inlet is disclosed. The particulate filter is located in an exhaust system of an internal combustion engine. The method of controlling exhaust gas temperature at the particulate filter inlet includes a late injection, whose quantity is estimated as function of an exhaust gas volumetric flowrate. | 09-25-2014 |
20140338434 | ADAPTIVE SOOT MASS ESTIMATION IN A VEHICLE EXHAUST AFTER-TREATMENT DEVICE - A method of estimating a total amount of soot in a diesel particulate filter includes monitoring a pressure differential across the diesel particulate filter; monitoring an engine speed and an engine load from an engine in fluid communication with the diesel particulate filter; determining a first soot mass estimate from the monitored pressure differential, the first soot mass estimate having an associated confidence indicator based on the monitored engine speed and engine load; determining a second soot mass estimate from the monitored engine speed and engine load; and outputting the first soot mass estimate if the confidence indicator is above a predetermined threshold, and outputting the second soot mass estimate if the confidence indicator is below the predetermined threshold. | 11-20-2014 |
20150267590 | SYSTEM TO MONITOR REGENERATION FREQUENCY OF PARTICULATE FILTER - An exhaust treatment system to treat exhaust gas includes a particulate filter configured to trap soot contained in the exhaust gas, and a pressure sensor that outputs a pressure signal indicative of a pressure differential of the particulate filter. A soot mass module is configured to determine a soot mass indicative of an amount of soot stored in the particulate filter based on the pressure differential. The soot mass is selectively determined according to a first soot model or a second soot model. An adaptation soot load module corrects the first soot model based on the second soot model such that the first soot model is adapted to the second soot model. A frequency regeneration module determines an actual rate at which the first soot model is corrected. The frequency regeneration module further determines the particulate filter is excessively regenerated based on the actual rate and a threshold. | 09-24-2015 |
