Title:
排気ガス浄化システムの制御方法及び排気ガス浄化システム
Document Type and Number:
Japanese Patent JP4175282
Kind Code:
B2
Abstract:
An exhaust gas control system (1) comprised with a continuous regeneration-type DPF (13), an exhaust throstle valve (16) and a DPF control means (30C), wherein the regeneration control is suspended, the multi injection control is performed, and the exhaust throttle valve is closed, when detecting a stop condition of the vehicle during the regeneration control of the continuous regeneration-type diesel particulate filter device (13) by the regeneration means. Thereby, concerning the regeneration of the continuous regeneration-type DPF device (13), the DPF can be regenerated securely by burning PM efficiently even in a traveling pattern of frequent waiting for the traffic lights to change in urban areas.
