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.

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： 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： An example emissions-control system of a vehicle includes a reservoir configured to contain a reductant solution, and an SCR device disposed in the exhaust system and configured to consume the reductant solution. The example emissions-control system further includes a base sensor responsive to whether a volume of the reductant solution exceeds a base volume, wherein the base volume is a sum of a dead volume of the reservoir plus a standard volume, and one or more elevated sensors corresponding to one or more elevated volumes. The example emissions-control system further includes an emissions sensor responsive to a NOX level in the exhaust system, and a misformulation indicator operatively coupled to the emissions sensor and to at least one of the base sensor and an elevated sensor, and configured to indicate when an excess NOX emission follows, within an interval, an increase in the volume of the reductant solution above the base volume or an elevated volume. The example emissions-control system may further include an insufficiency indicator operatively coupled to the base volume sensor and configured to indicate when the volume of the reductant solution becomes less than the base volume.
