摘要： An exhaust gas cleaning device estimates a deposition amount of exhaust particulate matters in a collector based on deposition characteristics correlating the deposition amount with a pressure loss at the collector. The deposition characteristics define a first range from an initial point, at which the deposition amount is zero, to a transitional point and a second range over the transitional point. The pressure loss increases more gradually in the second range than in the first range as the deposition amount increases. The exhaust gas cleaning device corrects the deposition characteristics such that the transitional point approaches the initial point, the pressure loss at the initial point increases and an increase ratio of the pressure loss to the increase of the deposition amount in the second range increases as an ash deposition amount increases.

摘要： In an exhaust gas purifying apparatus for a diesel engine having a diesel particulate filter provided in an exhaust pipe, a pressure loss at the filter is detected. An accumulated amount of diesel particulates in the filter is calculated based on the pressure loss and a map for a relationship between the pressure loss and the accumulated amount. A compulsory re-generating operation is carried out when the calculated accumulated amount reaches at a predetermined threshold value, which is decreased to a smaller value depending on a combustion amount of the diesel particulates which are combusted and removed from the filter as a natural re-generating operation.

摘要： An exhaust gas purifying device for an engine includes a particulate filter midway in an exhaust passage for collecting particulate matters. A control means calculates an accumulating amount of particulate matters on the particulate filter. An accumulating amount calculating means calculates the accumulating amount in accordance with an accumulating characteristic and differential pressure of the particulate filter detected using a differential pressure detecting means. When the accumulating amount becomes a predetermined regeneration demand amount, the control means performs a forcible regeneration, in which particulate matters on the particulate filter are burned and removed to regenerate the particulate filter.
