This invention provides improvements in method of and apparatus for reducing an emitted amount of particulates by collecting the particulates contained in the exhaust gas from a diesel engine by a trapper. According to the invention, firstly, an excess amount of the particulates which have adhered to the trapper is detected, and thereafter, temperature of the trapper being within a range of self-burning temperature of the particulates is detected. When necessity for regenerating the trapper is ascertained based on the both detections described above, the inlet side of the trapper is heated to a range of igniting temperature of the particulates, whereby a large igniting energy required for propagating combustion is accumulated. Thereafter, secondary air is supplied to the trapper to ignite the particulates, and combustion is propagated to the particulates being within the range of self-burning temperature thereof by the secondary air continuously supplied, to thereby regenerate the trapper.
