Title:
REGENERATION DEVICE FOR EXHAUST-GAS PURIFYING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/027736
Kind Code:
A1
Abstract:
In order to effectively raise the temperature of exhaust gas by combusting, in a cylinder, fuel supplied through post-injection, the present invention provides a regeneration device for an exhaust-gas purifying device 40 that is provided in an exhaust-gas system 20 of an internal combustion engine 10, the regeneration device including: an injector 11 that injects fuel into a cylinder; a glow plug 12 that produces heat through energization, thus increasing the temperature in the cylinder; and a regeneration control unit 50 that controls fuel injection of the injector 11 and energization of the glow plug 12 to execute regeneration processing for recovering the purification capacity of the exhaust-gas purifying device 40. When executing regeneration processing, the regeneration control unit 50 controls the fuel injection of the injector 11 through multistage injection, including at least post-injection, and also energizes the glow plug 12 at a predetermined duty ratio, thus combusting, in the cylinder, fuel supplied through post-injection.
