ABSTRACT:
An exhaust emission control device for an internal combustion engine is provided with a main catalyst activated with heat of exhaust gas, a self-exothermic type auxiliary catalyst activated with electric current energy and a silencer, which are connected in series and in sequence from an upstream side to a downstream side in an exhaust system leading from an engine body. Thus, noxious components included in the exhaust gas can be converted and the gas is purified by using the main and auxiliary catalysts in combination but with the auxiliary catalyst being subject to less heat from the exhaust gas than the main catalyst.
