DPF再生控制装置
摘要：
本发明目的在于提供一种能够比以往更高效地防止DOC的封堵、并且即使在DOC实际封堵的情况下也能够可靠地从封堵状态恢复的DPF再生控制装置，DPF再生控制装置(10)具备：DPF升温部件(10A)，其由使DPF(37)升高至规定温度的第1升温部件(12)、以及与该第1升温部件协同而使DPF升高至比所述规定温度高的第2升温部件(14)构成；DOC封堵检测部件(10D)，在自动再生的执行中检测出的与DOC(35)的封堵相关的封堵参数超过预先确定的封堵阈值规定时间时，检测为DOC已封堵；以及DOC封堵对策部件(10C)，在检测为DOC已封堵时，该DOC封堵对策部件中止自动再生，并且报告催促相比于自动再生使DPF升高至更高温的手动再生的执行的信息。
摘要（英）：

An object is to provide a DPF regeneration control device whereby it is possible to prevent clogging of a DOC more efficiently than conventional techniques, and to recover the DOC securely from a clogging condition even if the DOC is actually clogged. A DPF regeneration control device (10) includes: a DPF temperature-increase unit (10A) including a first temperature-increase unit (12) configured to heat a DPF (37) to a predetermined temperature, and a second temperature-increase unit (14) configured to heat the DPF to a temperature higher than the predetermined temperature in cooperation with the first temperature-increase unit; a DOC clogging detection unit (10D) configured to detect that a DOC (35) is clogged if a clogging parameter detected during execution of the automatic regeneration exceeds a clogging threshold value determined in advance for a predetermined period, the clogging parameter being related to clogging of the DOC , and a DOC clogging countermeasure unit (10C) configured to stop the automatic regeneration and issue an alert to prompt execution of the manual regeneration, if the clogging of the DOC is detected.
