Appl. No.:

11/298221

Inventors:

John Rollinger - Sterling Heights MI, US
Karen Willard - Grosse Pointe Farms MI, US
Paul Pietrzyk - Beverly Hills MI, US
Michael J. Cullen - Northville MI, US

Assignee:

Ford Global Technologies, LLC - Dearborn MI

International Classification:

G01M 15/00

US Classification:

731181, 731182

Abstract:

A drive system. The drive system includes an engine configured to convert chemical energy into mechanical energy, an electronically-controlled air throttle configured to regulate air delivery to the engine, a supercharger configured to selectively increase pressure of the air delivered to the engine, and a supercharger diagnostic system configured to diagnose supercharger over-boosting or under-boosting.

International Classification:

G01M 15/00

US Classification:

731182

Abstract:

A method for determining airflow to a cylinder of an internal combustion engine, such airflow passing to the cylinder through an intake manifold. The method includes providing a model of the intake manifold, such model providing a relationship between expected output airflow from the intake manifold in response to airflow into the intake manifold; determining from the model the expected output airflow from the intake manifold from a previous commanded airflow into the intake manifold; determining a compensation airflow required for the input airflow to the intake manifold to drive the expected output from the intake manifold towards the desired cylinder airflow; and providing such compensation airflow to the intake manifold.

International Classification:

F02B 33/00

US Classification:

1235593, 123564

Abstract:

A drive system. The drive system includes an engine configured to convert chemical energy into mechanical energy, an electronically-controlled air throttle configured to regulate air delivery to the engine, an electronically-controlled supercharger configured to selectively increase pressure of the air delivered to the engine, and a controller configured to variably engage the supercharger based on an operating parameter of the drive system.

International Classification:

F02D 41/04
F02D 41/22

US Classification:

701111, 701103, 123435, 123690

Abstract:

Methods and systems are provided for mitigating engine pre-ignition based on a feed-forward likelihood of pre-ignition and feedback from a pre-ignition event. In response to an indication of pre-ignition, a cylinder may be enriched while an engine load is limited. The enrichment may be followed by an enleanment to restore exhaust catalyst feed-gas oxygen levels. The mitigating steps may be adjusted based on engine operating conditions, a pre-ignition count, as well as the nature of the pre-ignition.

International Classification:

B60K 15/03
G01F 23/00

Abstract:

A method and a system for indicating more than three different fluid levels in a fluid reservoir is described for a system that includes a fluid level sensor having only two output levels. In one example, the more than three different fluid levels are determined via output of the fluid level sensor and output of one or more sensors that indicate acceleration or orientation of a vehicle.
