Title:
エンジン駆動発電機における排気ガス後処理装置の再生方法及び再生装置
Document Type and Number:
Japanese Patent JP6405207
Kind Code:
B2
Abstract:
In a continuous regeneration type exhaust gas post-processing apparatus equipped with an oxidation catalyst (DOC) and a diesel particulate filter (DPF), reliably removing particulate matter (PM) deposited to the DOC for maintaining the activity performance of DOC. The present invention relates to a method of forcibly regenerating a continuous regeneration type exhaust gas post-processing apparatus installed in an engine-driven generator equipped with a generator body driven by a diesel engine. When the engine is in a predetermined light load running state during forced regeneration in which intake gas to the engine is restricted to increase a temperature of exhaust gas, a heater actuated with electricity generated by the generator body switches ON in order to increase a load on the engine and thus a DOC inlet temperature of the exhaust gas post-processing apparatus to a burning temperature of PM deposited in the DOC or more.
