ABSTRACT:
An exhaust emission control system for a diesel engine including a trap in the form of a filter formed of heat-resistant material for trapping carbon particulates. The trap has no directionality with respect to air permeability, and combustion gas, for heating the trap or a fuel for activating a catalyst provided to the trap, is supplied to the trap from a direction substantially perpendicular to a direction in which an exhaust gas flows from the engine to the trap. Upon a blocking of the trap as a result of an accumulation of the trapped carbon particulates, the trapped carbon particulates can be removed by oxidation treatment, to thereby enable regeneration of the trap to be effected with a high degree of efficiency.
