<p>A regeneration system for a particulate trap (2) provided in an exhaust pipe (1a) of an engine in which the regeneration is initiated when the pressure loss across the trap (2) has reached a preset value. Then the preset value is renewed when the peak value of the trap temperature through the regeneration resides out of a predetermined range or when the pressure loss after the regeneration exceeds the preset value even though the peak value resides within said predetermined range. The initial value of said preset value is determined on the basis of the minimum value within the variation of the pressure loss of cleaned traps.</p> |
