A method for an exhaust system is provided, comprising adjusting reductant injection responsive to a reductant concentration, the reductant concentration based on concentration sensor readings and vehicle motion. If the reductant freezes, the reductant may stratify, leading to inaccurate concentration sensor readings. Vehicle motion may mix the reductant, thereby ensuring an accurate concentration measurement which may then be used to adjust reductant injection.

Systems and methods for managing diesel exhaust fluid stratification

A venting system for a filler pipe coupled to a diesel exhaust fluid tank in a vehicle is provided. In one example approach the venting system comprises a plurality of cut-outs in an interior surface of the filler pipe along the interior diameter of the filler pipe in a top surface of the filler pipe.

Venting system for a diesel exhaust fluid filler pipe

Various methods are provided for notifying a vehicle operator of various parameters based on an exhaust fluid level sensor of an exhaust fluid storage tank. In one example, the parameter is a consumption rate of the exhaust fluid. In another example, the parameter is an amount of fluid to be added to the exhaust fluid storage tank.

Methods for an exhaust fluid level sensor

Methods and systems are provided for conditioning fuel for diesel engine. The system may include a fuel pump located within a fuel tank configured to pump fuel to the diesel engine. The system may also include a fuel filter located outside of the fuel tank operatively located upstream of a flow of fuel from the fuel pump. A method may include directing fuel from inside of the fuel tank through a fuel filter located outside of the fuel tank into a vacuum chamber positioned inside the fuel tank, before directing the fuel to the diesel engine.

Diesel fuel system conditioning

A method of supplying fuel vapor to an exhaust aftertreatment device of a motor vehicle is provided. The method includes evaporating fuel on a voltage-biased, resistive heating element, the element set in an enclosure configured to release fuel vapor to the exhaust-aftertreatment device, and indicating that the element is degraded if a current flowing through the element is less than a threshold current. In some embodiments, the threshold current is based on the ambient temperature and/or the amount of fuel in the enclosure.

Method to detect fuel vaporizer coking

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.

System and method for monitoring reductant quality

A system for injecting from an injector into a duct of an engine system is provided. The system may include a first flange on a duct connection side, a second flange on an injector connection side, a stand-off separating the first flange from the second flange to form an air gap therebetween, and a seal offset from at least one of the first and the second flanges and located within the airgap and between the first flange and the second flange.

Liquid injector assembly with a flanged connector connection

A method is described for managing vapors generated from an ammonia-containing reductant delivery system. The method may include generating ammonia vapors in a first storage device and storing said generated ammonia vapors in a second storage device. Further, the method may include purging the stored vapors from the second storage device to upstream of a combustion chamber of the engine during a first condition and downstream of the combustion chamber during a second condition.

Ammonia vapor management system and method

A system comprises a fuel system for delivering fuel to an engine for combustion and a reductant storage system for delivering reductant to the exhaust stream for an SCR catalyst for NOx reduction. The fuel system further comprises a water separator for separating water-based fluid from fuel in the fuel tank, and a separation reservoir to collect the separated water-based fluid. Based on readings of a water-in-fuel sensor positioned within the reservoir, a type of degradation (e.g., water build-up, high-water-content fuel, mis-filling of the reductant, etc.) may be determined and indicated.

Contamination detection in fuel system

An exhaust system for an internal combustion engine for a vehicle is provided. The system comprises an exhaust passage with an angled injector and a plurality of mixing devices.
