摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device of an internal combustion engine capable of accurately estimating an ash deposit quantity after finishing complete regeneration of a DPF (diesel particulate filter). SOLUTION: Regeneration operation is performed up to the time t2 while erecting a regeneration performing flag as it is even after the time t1 when the complete regeneration of the DPF is finished. DPF differential pressure is measured up to t2 from the tine t1, and the ash deposit quantity in the DPF is estimated from a differential pressure value, and a characteristic between longitudinal differential pressure and a PN despot quantity in the DPF is corrected based on an estimate value. Since the regeneration operation is continued up to t2 from the tine t1, an exhaust flow rate is sufficient, and a DPF differential pressure value is improved in accuracy without reducing. Since the regeneration operation is further continued up to t2 from the time t1, PM is not deposited again, and the DPF differential pressure value is not influenced by redeposit of the PM. Thus, the ash deposit quantity can be accurately calculated from the DPF differential pressure value up to t2 from the time t1. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：提供能够在完成DPF（柴油机微粒过滤器）的完全再生后能够精确地估计灰分沉积量的内燃机的废气排放控制装置。解决方案：直到时刻t2执行再生操作，同时在DPF的完全再生完成之后的时间t1之后立即再生再生执行标志。 DPF压差从峰值t1测量达到t2，DPF中的灰分沉积量由差压值估计，DPF中的纵向压差和PN特殊量之间的特性基于估计值被校正值。由于再生操作从齿数t1持续到t2，所以排气流量就足够了，并且DPF差压值在不降低的情况下提高了精度。由于再生操作从时间t1进一步延续到t2，所以不再沉积PM，并且DPF压差值不受PM再沉积的影响。因此，从时间t1起，可以从DPF差压值直到t2精确计算灰沉积量。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device for an internal combustion engine capable of avoiding an excessive temperature rise of a DPF by properly selecting a manner for increasing an exhaust gas flow rate and transferring the heat of the DPF to a downstream side and a manner for throttling air intake and restraining the combustion of particulate matters (PM) while the PMs are burned in the DPF. SOLUTION: When a DPF temperature and a PM accumulation amount are larger than respective predetermined values in a non-injection operating state (S40:YES) and an engine speed is higher than a predetermined value (S60:YES), intake control 1 is executed for setting an intake throttle to be fully (or almost) opened and an EGR valve to be fully (or almost) closed (S70). When the DPF temperature and the PM accumulation amount are larger than respective predetermined values in a non-injection operating state (S40:YES) and the engine speed is lower than a predetermined value (S60:NO), intake control 2 is executed for setting the intake throttle to be fully (or almost) closed and the EGR valve to be fully (or almost) opened (S80).

摘要： PROBLEM TO BE SOLVED: To calculate an accumulation state based on a volume flow rate and pressure difference of a particulate filter and make regeneration time of the particulate filter appropriate. SOLUTION: An ECU 51 calculates the amount of pressure loss on an exhaust passage 3 in the downstream side of the particulate filter 32 fluctuating in accordance with an operating condition of an internal combustion engine, as the amount of the pressure loss on the exhaust passage 3 constituting part of difference between absolute pressure of exhaust gas flowing through the particulate filter 32 and the atmospheric pressure, on the basis of the operating condition of the engine, and converts the mass flow rate of the exhaust gas flowing through the particulate filter 32 into the volume flow rate, based on the obtained absolute pressure. Accordingly, the volume flow rate is accurately obtained regardless of the fluctuation of the operating condition, and the accumulation state of exhaust particulates can be highly accurately grasped. This can make the regeneration time more appropriate. COPYRIGHT: (C)2005,JPO&NCIPI
