Abstract

PURPOSE:To effectively reduce a noxious exhaust gas created at burning of an exhaust gas fine particles collective filter for restoration, by bypassing an exhaust gas flow and reducing EGR at said restoration time of the filter. CONSTITUTION:Normally, some exhaust gas from an engine 1 runs from a branch pipe 7a into a particle collective fileter 8 for purification and then is discharged, while the other is led from the outlet of the filter 8 by a pipe 11 into a suction pipe 3 via a control valve 12 for exhaust gas recirculation (EGR). The control valve 12 is controlled by a controller 13 according to engine states. When the filter 8 is choked, the controller 13 changes over a switch valve 9 so that the exhaust gas flow may runsthrough a bypass pipe 7b to bypass the filter 8, and activates a combustor 10 to burn particles in the filter 8. In addition, the controller 13 throttles the control valve 12 to reduce the EGR and supplies a little exhaust gas which contains a combustion gas being recreated, thereby providing effective EGR.
