Abstract: Aspects of the invention relate to a customer authentication system for authenticating a customer making a request related to a customer account. The customer authentication system may include multiple application level data receiving and processing mechanisms for receiving customer requests and collecting customer data. The customer authentication system may additionally include a central authentication system for receiving the customer requests and customer data from the multiple application level data receiving and processing mechanisms, the central authentication system determining, based on authentication policy, whether the collected customer data is sufficient to authenticate each customer in order to fulfill the customer request. The central authentication system may return its conclusions and instructions to the multiple application level data receiving and processing mechanisms.

Abstract: The systems and method described above in the present disclosure allow for regeneration of a diesel particulate filter while a vehicle is in stationary power take-off mode. Described is a method of: during select power take-off conditions, reducing an EGR rate responsive to an indication to regenerate a diesel particulate filter.

Abstract: A method of operating an internal combustion engine having a reductant delivery and storage system in an emission control system, comprising of correlating a change in a monitored operating condition with a refill event to determine whether a reductant-diluting substance has been added to the reductant storage system; and limiting vehicle operation based on the correlation.

Abstract: A turbine engine assembly includes a turbine engine case, a gearbox and a plurality of gearbox mounts that connect the gearbox to the case. The case extends along an axis between an upstream end and a downstream end. The gearbox mounts include an axial mount that extends axially in an upstream direction from the gearbox to the case.

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 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.

Abstract: A method is provided for managing vapor generation in a reductant storage and delivery system. In one example, urea vapors generated from liquid in a storage device are temporarily stored and later purged to the exhaust system of the engine.

Abstract: A method for operating an internal combustion engine Exhaust Gas Recirculation (EGR) system that includes producing an EGR valve position signal to decrease the amount of exhaust gas passed to the EGR cooler when a processor determines the EGR cooler efficiency is less than the predetermined level and producing an EGR coolant valve position signal to decrease the amount of coolant passed to the EGR cooler when such processor determines the EGR cooler efficiency is less than the predetermined level. The processor produced EGR valve and the EGR coolant valve position signals result in regeneration within the cooler, returning the effectiveness of the cooler to a near “clean” condition.

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.
