Abstract:
1. System for controlling particulate filter temperature, the system comprising: an internal combustion engine producing exhaust gas at an exhaust gas outlet; a particulate filter having a filter inlet fluidly coupled to said exhaust gas outlet and a filter outlet; means for determining a volumetric flow rate of said exhaust gas entering said filter inlet; means for determining a pressure differential between said filter inlet and said filter outlet; a transmission coupled to said engine, said transmission including a number of automatically selectable gear ratios; and a control circuit determining a regeneration parameter as a function of said pressure differential and said volumetric flow rate, said control circuit controlling automatic shifting of said transmission as a function of said regeneration parameter.
