US Patent:

20140069394, Mar 13, 2014

Filed:

Sep 11, 2012

Appl. No.:

13/610720

Inventors:

Robert Roy Jentz - Westland MI, US
Mark W. Peters - Wolverine Lake MI, US
Michael Casedy - Ann Arbor MI, US
Aed M. Dudar - Canton MI, US

Assignee:

FORD GLOBAL TECHNOLOGIES, LLC - Dearborn MI

International Classification:

F02M 33/00

US Classification:

123520

Abstract:

Methods and system are provided for identifying unintended closing (or corking) of a mechanical valve coupled to a fuel tank. If tank vent valve corking is identified during a leak test, fuel tank pressure data collected during the leak test is disregarded and not used to determine a fuel system leak. Instead, a fuel system leak test is repeated to improve reliability of test results.

International Classification:

F02D 41/04
G06F 15/00
G01N 33/00

US Classification:

123672, 73 106, 702182

Abstract:

A method of monitoring an exhaust gas sensor coupled in an engine exhaust is provided. The method comprises indicating exhaust gas sensor degradation based on a difference between a first set of estimated parameters of a rich operation model and a second set of estimated parameters of a lean operation model, the estimated parameters based on commanded lambda and determined lambda values collected during selected operating conditions. In this way, sensor degradation may be indicated with data collected in a non-intrusive manner.

Michael Casedy - Ann Arbor MI, US

International Classification:

F01N 3/18
F01N 13/00
F01N 11/00
F01N 3/035

Abstract:

Methods and systems are provided for differentiating an exhaust air leak from a catalyst monitor sensor degraded with a slow-response. In one example, a pressure proximate an exhaust system particulate filter less than a threshold pressure may indicate an exhaust air leak and responsive to the indication of the exhaust air leak, the thresholds for monitoring the catalyst monitor sensor response may be adjusted. In this way, the impact of an exhaust air leak on catalyst monitor output may be accounted for so that subsequent monitoring for threshold catalyst may continue to be performed accurately in the presence of an exhaust air leak.

Appl. No.:

14/512967

Inventors:

- Dearborn MI, US
Imad Hassan Makki - Dearborn Heights MI, US
Brent Edward Sealy - Plymouth MI, US
Michael Casedy - Ann Arbor MI, US

International Classification:

F01N 11/00

Abstract:

A method is provided for monitoring an emission control device coupled to an engine. In one example approach, the method comprises, following a deceleration fuel shut-off (DFSO) duration, indicating degradation of an emission device based on an amount of rich products required to cause a sensor to become richer than a first threshold, the indicating carried out when DFSO duration is greater than a second threshold. The method also comprises an integration which is based on inlet air-fuel ratio, the integration starting only after a pre-catalyst sensor reaches stoichiometry.

International Classification:

F02D 41/14
F02D 41/22

Abstract:

Methods and systems are described for evaluating presence of fuel shifts in an engine. In one example, a method comprises indicating a fuel shift based on a time delay of an exhaust gas sensor during an entry into and an exit out of deceleration fuel shut off (DFSO).

International Classification:

F02D 41/02
F01N 3/20
F01N 11/00

Abstract:

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.

G01M 15/10

Abstract:

A method for monitoring an exhaust gas sensor coupled in an engine exhaust is provided. In one embodiment, the method comprises indicating exhaust gas sensor degradation based on shape of a distribution of extreme values of a plurality of sets of lambda differentials collected during selected operating conditions. In this way, the exhaust gas sensor may be monitored in a non-intrusive manner.

International Classification:

F02D 41/30

US Classification:

123672

Abstract:

Methods and systems are provided for converting an asymmetric degradation response of an exhaust gas sensor to a more symmetric degradation response. In one example, a method includes adjusting fuel injection responsive to a modified exhaust oxygen feedback signal from an exhaust gas sensor, the modified exhaust oxygen feedback signal modified by transforming an asymmetric response of the exhaust gas sensor to a more symmetric response. Further, the method may include adjusting one or more parameters of an anticipatory controller of the exhaust gas sensor based on the modified symmetric response.
