Systems and methods for controlling a gasoline urea selective catalytic reductant catalyst are described. In one example, an observer is provided that corrects an estimate of an amount of NHthat is stored in a SCR. The amount of NHthat is stored in the SCR is a basis for generating additional NHor ceasing generation of NH.

Methods and system for controlling selective catalytic reductant catalyst of a gasoline engine

Various systems and methods are described for deactivation and reactivation of a cylinder bank in a V-engine. In one example, the cylinder bank is deactivated responsive to an indication of misfire based on crankshaft acceleration and exhaust air fuel ratio. The cylinder bank is reactivated sequentially based on exhaust catalyst temperature.

Methods and systems for cylinder bank misfire detection and reactivation

Systems and methods for diagnosing operation of a catalyst are presented. In one example, threshold limits for catalyst variables are adjusted in response to attributes of a catalyst monitor sensor that may vary with sensor age. The catalyst variables may provide insight into whether or not the catalyst is degraded or operating as intended.

Systems and methods for improving catalyst diagnostics in the presence of sensor degradation

Methods are provided for determining ice formation during cruising under cold weather conditions at the intake manifold or throttle body of an engine system and for enabling engine misfire diagnostics upon detection of dissipation of the formed ice.

Method of inferring start-up misfires due to the build-up of ice and melt water in the intake system of a vehicle engine

A method of monitoring catalyst performance may comprise applying a set of parameter readings for a given sample to a support vector machine to generate a classification output, clustering the set of parameter readings to reduce a number of support vectors, computing a total fuel mass following a deceleration fuel shut-off event and an exhaust gas oxygen sensor switch and indicating catalyst degradation based on the total fuel mass.

Integrated fuel catalyst monitor

A method of monitoring evaporative emissions of a vehicle includes the steps of establishing a baseline pressure within a vehicle evaporative emission system during the occurrence of a vehicle-off condition, detecting a change in the baseline pressure during the vehicle-off condition, and indicating whether the change in the baseline pressure is within a desirable limit.

Diagnostic method for vehicle evaporative emissions

A fuel weathering method for an evaporative emission system of a motor vehicle includes determining a current temperature of liquid fuel inside the evaporative emission system, determining a fuel residency time representing the amount of time the fuel has resided above the current temperature, and performing a system diagnostic test of the evaporative emission system only if the fuel residency time exceeds a minimum fuel residency time.
