    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： 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.
