(ZH) 排气净化系统的控制装置
要約
(EN) The present invention addresses the problem of suppressing the execution of a filter regeneration process in conditions that could induce an excessive temperature increase in a particulate filter, when there is a discrepancy between the amount of PM sediment determined by an ECU and the actual amount of PM sediment, as a result of an action such as replacing the ECU or the particulate filter. In order to overcome this problem, it is assumed in the present invention that a value measured by a differential pressure sensor is a value for when only PM has accumulated in a particulate filter when the difference between an estimated amount of PM sediment estimated from the operation history for an internal combustion engine and the amount of PM sediment calculated from the value measured by thedifferential pressure sensor is equal to or greater than a threshold value. If the measured value is equal to or less than a prescribed upper limit value, a first regeneration process is executed, which is a process of oxidizing and removing PM accumulated in the particulate filter, and if the measured value is greater than the prescribed upper limit value, a second regeneration process is executed without executing the first regeneration process.
(ZH) 本发明提供排气净化系统的控制装置,课题在于抑制在以ECU、颗粒过滤器的更换等为起因而导致由ECU求出的PM堆积量与实际的PM堆积量发生了背离的情况下,在有可能招致颗粒过滤器的过度升温的状态下执行过滤器再生处理。为了解决该课题,在本发明中,在根据内燃机的运转历史记录推定的推定PM堆积量与根据差压传感器的测定值运算的PM堆积量之差为预定的阈值以上的情况下,假定所述差压传感器的测定值是在颗粒过滤器仅堆积有PM的状态的值,若该测定值为预定的上限值以下,则执行将堆积于所述颗粒过滤器的PM氧化及除去的处理即第一再生处理,并且,若所述测定值大于所述预定的上限值,则不执行所述第一再生处理而执行第二再生处理。
