Abstract

Official abstract text for this publication.

An exhaust gas purifying apparatus for a diesel engine includes a diesel particulate filter (DPF) in an exhaust system in the diesel engine. The exhaust gas purifying apparatus is constructed to execute regeneration of the DPF by raising a temperature of the DPF in a case where a predetermined DPF regeneration condition is fulfilled, interrupt the regeneration of the DPF, execute idling stop, automatically restart the diesel engine and then restart the regeneration of the DPF, and when shifting to the idling operation is carried out during regeneration of the DPF, delay execution of the idling stop until a temperature of the DPF at a time at which the idling stop is started becomes not less than a temperature of the DPF at a time at which shifting to an idling operation is carried out even in a case where the predetermined idling stop condition is fulfilled.

First claim
