摘要： A diesel particulate filter (DPF) for trapping exhaust particulates is located in an exhaust passage of a diesel engine. Deposit amounts of a soluble organic fraction (SOF) as an organic solvent soluble component and soot as a solid carbon component of exhaust particulate components deposited in the DPF are estimated respectively. When the SOF deposit amount reaches an SOF elimination execution deposit amount, the DPF is heated to or over relatively low SOF combustion temperature to execute SOF elimination treatment. When the soot deposit amount reaches a soot elimination execution deposit amount, the DPF is heated to or over relatively high soot combustion temperature to execute soot elimination treatment. The SOF elimination treatment is executed before the SOF becomes excessive to prevent rapid combustion of the soot due to combustion of the SOF.

摘要： The amount of accumulated particulate matter, which is accumulated in a particulate filter, is computed based on the amount of exhausted particulate matter, which is exhausted from an engine, and the amount of reduced particulate matter, which is reduced in the filter. The amount of reduced particulate matter includes the amount of reduced particulate matter, which is reduced through oxidizing reaction of the accumulated particulate matter with NO2. At the time of computing this amount, reduction of the particulate matter through oxidizing reaction with adsorbed NO2, which is adsorbed by the accumulated particulate matter, is concerned in addition to reduction of the particulate matter through oxidizing reaction with NO2, which is present in the surrounding atmosphere around the accumulated particulate matter.

摘要： A method is disclosed for estimating an amount of deposited particulates (PM) in a collector of an internal combustion engine. The method includes estimating the amount of inflow of PM into the collector and estimating a basic amount of decreased PM that flows into the collector and is burned and decreased. The method also includes estimating the amount of ash deposited on the collector. The method further includes correcting the basic amount of decreased PM based on the estimated amount of ash. Moreover, the method includes estimating an amount of deposited PM by a history expression based on the estimated amount of inflow of PM and the corrected amount of decreased PM. A related device is also disclosed.

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.
