Abstract
Official abstract text for this publication.
In a case where DPF regeneration is restarted after an engine is automatically restarted from interruption of the DPF regeneration, DPF regeneration control is corrected so as to suppress temperature rise due to the DPF regeneration in consideration of an increment in oxygen concentration in exhaust gas which is caused due to the interruption of the DPF regeneration. Specifically, restart of the DPF regeneration is prohibited during a predetermined prohibition time ΔT1 from a time t1 at which the engine is automatically restarted, and a post injection amount of fuel is corrected to the side of reduction.
First claim
Opening claim text (preview).
The invention claimed is: 1. An exhaust gas purifying system for a diesel engine that carries out idle stop to automatically stop the diesel engine during an idling operation, the exhaust gas purifying system comprising: a diesel particulate filter (DPF) disposed in an exhaust system of an engine and serving to trap particulate matter present in exhaust gas; and a controller configured to control: a DPF regeneration section to execute DPF regeneration for the diesel particulate fil…
