<p>PURPOSE:To carry out the regeneration of a filter member safely and securely by feeding a catalytic additive for assisting the combustion of particulates into an intake system in accordance with the accumulated quantity of the particulates in exhaust gas collected by a filter member provided in an exhaust system. CONSTITUTION:A filter member 11 for collecting particulates in exhaust gas is provided in an exhaust system 3 of an exhaust manifold, etc. of a diesel engine 1. On the other hand, a device 7 for feeding a catalytic additive for assisting the combustion of the particulates is provided on the intake system 2 of an intake manifold, etc. Also, a device 5 detects the rise in the pressure of an exhaust gas on the upper course side of the filter member 11 accompanying the accumulated quantity of the particulates collected by the filter member 11. And, signals from the detecting device 5, etc. are inputted into an electric control device 10. Thereby, a proper quantity of a catalytic additive corresponding to the accumulated quantity of the particulates can be fed into an intake air from the feeding device 7.</p> |
