    摘要: A system and method for controlling an internal combustion engine senses differential pressure across the diesel particulate filter to monitor at least one of soot cake permeability and filter wall permeability as a function of exhaust temperature and mass flow velocity. The system and method preferably respond to both porous wall and soot cake permeabilities to determine when the soot level matches a threshold at which an operator may be warned, or at which a remedial operation may be triggered, or at which a more protective action taken by the engine control module.

    摘要: A method for cold start white smoke protection of a hydrocarbon after treatment device, and method of engine operation to effect the same. The method comprises a) determining the temperature of the hydrocarbon after-treatment device during cold start conditions; b) determining hydrocarbon emissions in the hydrocarbon after-treatment device; and c) modifying engine operating conditions to raise the hydrocarbon after-treatment temperature at a pre-determined rate to a temperature sufficient to permit controlled oxidation of the hydrocarbons in the hydrocarbon after treatment device.
