    Abstract: 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.

    Abstract: 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.
