摘要： A method for improving the effectiveness of filters by increasing accuracy of an estimate of particulate matter loading remaining in the filter after cleaning. In one embodiment, the disclosed method includes removing soot from the DPF by cleaning, and measuring parameters for a set of predetermined criteria. The amount of soot present in the DPF is then estimated based on delta pressure. The resulting estimated soot load value accounts for the noise factors such as ash loading after extended operation. The value is then used to adjust for future measurements of soot loading in the DPF after subsequent regeneration treatments and/or used to diagnose the effectiveness of the cleaning. The method can also be applied to diagnostics of the DPF. When discrepancies between DPSLE and model-based soot load estimate are observed in healthy regenerations, failure modes such as plugged filter, extreme ash loading or substrate melting can be detected.
摘要翻译：一种通过提高清洁后残留在过滤器中的颗粒物质负载的估计精度来提高过滤器有效性的方法。在一个实施例中，所公开的方法包括通过清洁从DPF去除烟灰，以及测量一组预定标准的参数。然后，基于δ压力来估计存在于DPF中的烟灰量。所得到的估计的烟灰负荷值解释了延长操作后的灰分负荷等噪声因素。然后，该值用于随后的再生处理和/或用于诊断清洁的有效性，以便将来测量DPF中的烟灰负荷。该方法也可以应用于DPF的诊断。在健康再生中观察到DPSLE和基于模型的烟灰负荷估计之间的差异，可以检测到堵塞过滤器，极端灰分负载或底物熔化等故障模式。

摘要： A system, method and computer operable code is disclosed for reducing HC and liquid accumulation in an exhaust gas treatment system. A timer is used to monitor the amount of time the system spends in either absorption mode or desorption mode. If the exhaust gas temperature at the inlet of a oxidation catalyst device is below an absorption threshold, the timer is instructed to count up. If the exhaust gas temperature is above a desorption threshold, the timer is instructed to count down. At a predetermined timer threshold value, the engine is instructed to enter a thermal management mode operable to reduce accumulation of HC and liquid in the exhaust gas management system.

摘要： In a system, an engine includes an exhaust system with a particle filter operable to collect particulate matter in exhaust produced by the engine, a sensor arrangement, a controller, and one or more engine control devices. The sensor arrangement provides a first sensor signal representative of oxygen in the exhaust and a second sensor signal representative of a temperature of the particle filter. The controller regulates operation of the particle filter in response to the sensor arrangement. The controller is structured to generate one or more output signals corresponding to a minimum exhaust flow rate as a function of the first and second sensor signals. The control devices are responsive to the one or more output signals to provide the minimum exhaust flow rate to the filter.

摘要： A method includes providing a system having a fluid flow, a fuel injector and an oxygen sensor disposed in the fluid flow, where the oxygen sensor is downstream of the fuel injector. The method includes determining a first air fuel ratio, changing an injection rate of the fuel injector and determining a second air fuel ratio, and determining a fault value for the fuel injector from the first air fuel ratio and the second air fuel ratio. The method further includes determining the fault value for the fuel injector by determining a difference between the first air fuel ratio and the second air fuel ratio, and by determining that the fault value is positive in response to the difference being lower than a passing threshold value. The method includes changing injection rates of the fuel injector for specified periods of time short enough to significant disruption of system temperatures.
