Fuel Injector Spray Pattern For Direct Injection Spark Ignition Engines
view source
US Patent:

7418940, Sep 2, 2008
Filed:

Aug 30, 2007
Appl. No.:

11/847381
Inventors:

Jianwen James Yi - Canton MI, US
Claudia Olivia Iyer - Canton MI, US
Brad Alan VanDerWege - Canton MI, US
Steven Wooldridge - Saline MI, US
Assignee:

Ford Global Technologies, LLC - Dearborn MI
International Classification:

F02B 17/00
US Classification:

123295
Abstract:

A system and method for operating an internal combustion engine include injecting fuel through a plurality of fuel jets of a fuel injector directly into a corresponding cylinder with at least a first plurality jets oriented to primarily support operation in a stratified mode and a second plurality of jets oriented to primarily support operation in a homogeneous mode. The first plurality of jets is oriented to spray fuel generally downward toward the piston bowl and the second plurality of jets is oriented to spray fuel generally across the cylinder toward the exhaust valves. The spray jets reduce or eliminate valve, liner, and piston wetting while providing good mixing in homogeneous mode and good combustion stability for light stratified charge during cold starts to achieve desired targets for feedgas emissions and combustion efficiency.

Oct 2, 2007
Appl. No.:

11/865748
Inventors:

Jianwen James Yi - Canton MI, US
Steven Todd Wooldridge - Saline MI, US
George Carver Davis - Ypsilanti MI, US
Assignee:

US Classification:

701105, 701104, 123299, 123480
Abstract:

A system and method for controlling operation of a multiple cylinder direct injection internal combustion engine include injecting fuel directly into the combustion chamber during the exhaust stroke at high engine speeds and loads to reduce the effect of intake airflow on the injection spray and improve fuel-air mixture homogeneity.

Assignee:

Ford Global Technologies, LLC - Dearborn MI
International Classification:

F02P 15/08
US Classification:

123636, 1231793, 1231795, 12333911, 12340653, 12340625
Abstract:

A method for operation of a vehicle having an internal combustion engine is provided. The internal combustion engine may include one or more combustion chambers, a fuel delivery system including a direct fuel injector coupled to each combustion chamber, an ignition system including one or more spark plugs coupled to each combustion chamber, a piston disposed within each combustion chamber, and an intake and an exhaust valve coupled to each combustion chamber, the internal combustion engine providing motive power to the vehicle. The method may include discontinuing combustion operation within the internal combustion engine responsive to idle-stop operation. The method may further include, during a direct-start, performing multi-strike ignition operation per combustion cycle via one or more selected spark plug(s) for at least a first combustion cycle in a combustion chamber following the discontinuation of combustion operation, the one or more selected spark plug(s) coupled to the combustion chamber.

Filed:

Oct 29, 2010
Appl. No.:

12/915666
Inventors:

Alex O'Connor Gibson - Ann Arbor MI, US
Jianwen James Yi - Canton MI, US
Brad Alan VanDerWege - Canton MI, US
Joseph Norman Ulrey - Dearborn MI, US
Cindy Zhou - Canton MI, US
Steven Todd Wooldridge - Saline MI, US

International Classification:

F02P 15/08
US Classification:

123636, 1231793, 1231795, 12333911, 12340625, 12340653
Abstract:

A method for engine starting is provided. The method may include performing idle-stop operation, and during a subsequent re-start, applying multi-strike ignition operation for a first combustion cycle. In this way, improved engine starting may be achieved with reduced emissions.

Shallow Piston Bowl And Injector Spray Pattern For A Gasoline, Direct-Injection Engine

US Patent:

8056531, Nov 15, 2011
Filed:

Jun 24, 2010
Appl. No.:

12/822296
Inventors:

Zheng Xu - Canton MI, US
Jianwen James Yi - Canton MI, US
Steven Wooldridge - Saline MI, US
David Bruce Reiche - Livonia MI, US
Neal James Corey - Canton MI, US
Stephen George Russ - Canton MI, US
Steven Paul Penkevich - New Hudson MI, US
Claudia Olivia Lyer - Canton MI, US
Assignee:

Ford Global Technologies LLC - Dearborn MI
International Classification:

F02B 5/00
F02F 3/00
US Classification:

123305, 123280
Abstract:

A combustion system for a direct-injection, spark-ignition engine is disclosed. A side-mounted fuel injector located outboard the intake valves directs multiple fuel jets into a shallow, spherical bowl formed in a domed piston. Both good mixing to facilitate good air utilization with early injection and an ignitable mixture at the spark plug with late injection to facilitate cold start are provided with such a combustion system. Because the bowl is smooth and shallow, the surface area of the combustion chamber is less than with a deeper bowl of complicated shape. Lowering surface area in the combustion chamber leads to improved fuel economy.

International Classification:

F01L 13/08
US Classification:

1231821, 123685, 1231797, 1231798
Abstract:

A method for improving starting of an engine that may be operated with fuels having varying alcohol concentrations is presented. In one embodiment, the method adjusts a compression ratio of an engine in response to a number of combustion events after an engine stop and a concentration of alcohol in a fuel supplied to the engine. The method may make engine starting more repeatable at lower engine temperatures.
