Title:
CONTROL SYSTEM FOR DPF REGENERATION BY EXHAUST PIPE INJECTION, AND REGENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2013/077028
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a DPF travel-time regeneration control system capable of stably raising the temperature even during travel and capable of decreasing the frequency of DPF regeneration when the vehicle is stopped. In this control system, if the DPF (5) needs to be regenerated, the vehicle is travelling on cruise control, and the exhaust temperature detected by an exhaust temperature sensor (11) is higher than a threshold value, then fuel is injected into the exhaust pipe by a fuel injection means (7), and if the exhaust temperature is lower than the threshold value, the exhaust temperature is raised by operating the exhaust brake without injecting fuel into the exhaust pipe.
