Filed:

Dec 15, 2005

Appl. No.:

11/305263

Inventors:

Hugh Fader - Royal Oak MI, US
Christopher Warren - Farmington Hills MI, US

Assignee:

Ford Global Technologies, LLC - Dearborn MI

International Classification:

F02M 7/28

US Classification:

123435, 123295

Abstract:

An internal combustion engine having a plurality of combustion cylinders configured to operate in a compression ignition mode. A pressure sensor is provided to sense pressure within a combustion cylinder of the engine. A combustion control system, including an electronic engine controller, is configured to receive electrical signals from the pressure sensor and, based on such signals, determine a maximum rate of pressure increase occurring in the combustion cylinder during a first time interval. Based on the determined maximum rate of pressure increase, the combustion control system is configured to control one or more charge inputs to the combustion cylinder during a second time interval.

Ronald Lee Martelli - Ann Arbor MI
Christopher Warren - Farmington Hills MI
William Francis Stockhausen - Northville MI

Assignee:

Ford Global Technologies, Inc. - Dearborn MI

International Classification:

F02B 1700

US Classification:

123295

Abstract:

A variable valve controlled engine causes the inducted exhaust residual to flow from the exhaust port(s) into specific regions of the combustion chamber and remain substantially separate from the air-fuel mixture, thereby creating stratification. The exhaust gas remains substantially on the piston surface and along the entire cylinder wall for at least a portion of the cylinder, with the air-fuel mixture occupying the remaining portion of the chamber.
