Abstract
Fuel is added to exhaust gasupstream of a catalytic regeneration type particulate filterin an exhaust pipe. The fuel added is oxidized on a flow-through type oxidization catalystbefore the particulate filterto generate exothermic heat with which captured and accumulated particulates in the particulate filterare burned off to forcibly regenerate the particulate filter. When the driving is being performed in light-load engine operation areas upon forcible regeneration of the particulate filter, a retarderis activated, with an accelerator pedal retaining its on-state, and an amount of fuel injected is increased to compensate reduction of torque due to such activation of the retarder
