摘要： As such in one approach a method for operating an engine including a DPF is provided. The method including adjusting a post fuel injection amount based on a rate of change of engine torque during DPF regeneration. As one example, the adjusting includes reducing the amount when the rate of change is positive, and increasing the amount when the rate of change is negative. Furthermore, the method may also include delivering exhaust gas to a turbocharger turbine, to an oxidation catalyst, and then a DPF, the adjusting of the post fuel injection further based on thermal inertia of the turbocharger.

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： Modification of reductant (e.g., diesel exhaust fluid, DEF) tank location, for example during vehicle up-fitting may result in less than optimal operation of the DEF system due to inaccurate DEF system calibration. In one example approach, the above issue can be at least partially addressed by adjusting control system parameters for system control and diagnostics based on an input indicative of, or any modification to, the DEF tank location. In this way, DEF tank location flexibility is maintained, while also maintaining emission control and diagnostic accuracy.

摘要： A method of managing vapors generated from an ammonia-containing reductant delivery system for a vehicle is described. The method may include storing ammonia containing vapors generated in the reductant delivery system during engine-off and then purging said stored ammonia into an exhaust of the engine to react in a catalyst in the exhaust flow during engine operation.

摘要： Systems and methods are described for controlling an engine in a vehicle. One example method includes, after a threshold duration of engine idling, continuing engine idle operation when an exhaust NOx sensor indicates a NOx level below a NOx threshold, and stopping engine idle and shutting down the engine when the exhaust NOx sensor indicates the NOx level is above the NOx threshold.

摘要： Systems and methods are described for controlling an engine in a vehicle. One example method includes, after a threshold duration of engine idling, continuing engine idle operation when an exhaust NOx sensor indicates a NOx level below a NOx threshold, and stopping engine idle and shutting down the engine when the exhaust NOx sensor indicates the NOx level is above the NOx threshold. In this way, when the exhaust emissions are below the NOx threshold, it is possible to prolong engine idling operation using the exhaust NOx sensor.
