摘要： Termination of regeneration of a particulate filter may be based on a variable percent threshold of stored particulate, where the percent threshold of stored particulate depends on a current soot burn rate. In one example approach, a method for controlling regeneration of a diesel particulate filter comprises: terminating regeneration based on a particulate burning rate; wherein the particulate burning rate is based on operating conditions of the diesel particulate filter; the operating conditions including an amount of stored particulate in the diesel particulate filter and a temperature of the diesel particulate filter.

摘要： Systems and methods for updating the PF soot load of an engine are provided herein. In one embodiment, the method may include performing regeneration in response to both pressure-based measurements as well as estimated soot loading independent of the pressure-based measurements, where during conditions in which the pressure-based measurements may be inaccurate, the soot load is estimated based on operating conditions and previous pressure-based measurements that occurred during previous conditions in which the pressure-based measurements are more accurate. In this way, more continuous monitoring of particulate filter loading is provided, while taking advantage of pressure-based measurements from the most recent accurate reading, for example, and operating conditions that have transpired since such reading, including transient conditions. Thus, more appropriately timed regeneration may be provided.
摘要翻译：这里提供了用于更新发动机的PF烟灰负荷的系统和方法。在一个实施例中，该方法可以包括响应于基于压力的测量以及估计的烟灰负载执行再生，而与基于压力的测量无关，其中在基于压力的测量可能不准确的条件下，烟炱负载为基于在基于压力的测量更准确的先前条件下发生的基于操作条件和先前基于压力的测量来估计。以这种方式，提供了对颗粒过滤器负载的更连续的监测，同时利用来自最近的精确读数（例如，由于这种读取，包括瞬态条件）而发生的操作条件的压力测量。因此，可以提供更合适的定时再生。

摘要： Methods for monitoring and detecting undesired exotherms which may occur in an exhaust aftertreatment system coupled to a lean burning combustion engine are described. In one particular approach, an undesired exotherm may be indicated based on an expected oxygen depletion along a length of an exhaust aftertreatment system in the direction of exhaust gas flow of exhaust gas. For example, during DPF regeneration, a certain amount of oxygen is expected to be utilized for removing soot. If less oxygen is actually found in the exhaust downstream of the exhaust system, then an undesired exotherm may be present, as unintended reductant may be present in the exhaust and reacting exothermically with oxygen. Various mitigation actions may then be initiated in response to the indication of an undesired exotherm.
摘要翻译：描述了用于监测和检测可能发生在联合到稀燃燃烧发动机的排气后处理系统中的不期望的放热的方法。在一种特定方法中，可以基于排气后处理系统沿废气排气方向的长度的预期氧耗竭来指示不需要的放热。例如，在DPF再生期间，预期将一定量的氧用于除去烟灰。如果在排气系统下游的排气中实际发现氧少，则可能存在不需要的放热，因为排气中可能存在非预期的还原剂，并与氧气放热反应。然后响应于不期望的放热的指示可以启动各种缓解动作。

摘要： A system and method for controlling an engine control an EGR cooler bypass valve to divert at least a portion of EGR flow around an EGR cooler when operating under cooler fouling/plugging conditions, such as during idle, off-idle, exhaust system warm up and DPF regeneration or other post injection operation with EGR gas temperature below a corresponding threshold or with EGR low-temperature coolant temperature below a corresponding threshold. The system and method reduce exhaust gases passing through the EGR cooler that contain a high concentration of unburned or partially unburned fuel when the temperature in the EGR system is lower than the fuel condensation temperature.

摘要： Systems and methods for controlling regeneration of a diesel particulate filter in a vehicle engine exhaust include detecting a distance of an object from the exhaust and controlling a regeneration event if the distance is less than a threshold value. The system and method may include a particulate filter disposed in the exhaust of the vehicle and a proximity sensor disposed adjacent an exhaust opening and positioned to detect presence of an object near the opening. A controller in communication with the proximity sensor is adapted for controlling regeneration of the particulate filter in response to the proximity sensor detecting the object near the opening.
