Filed:

Dec 9, 2002

Appl. No.:

10/314671

Inventors:

Michael P. Kennedy - Wheaton IL
Michael J. McNulty - Lombard IL
James T. Beaucaire - Glen Ellyn IL
David V. Rodgers - Bloomingdale IL

Assignee:

International Engine Intellectual Property Company, LLC - Warrenville IL

International Classification:

F02M 2507

US Classification:

12356821, 123492, 701108

Abstract:

Engine speed data N and engine fueling data MFDES are processed by a strategy ( ) that multiplies ( ) fueling transient data MFDES TRANSIENT and speed-based modifier data EGR_N_TRANS_MULT to develop speed-based fueling transient data. The speed-based fueling transient data is then processed according to a function ( ) that correlates values of a fueling transient modifier with values of speed-based fueling transient data to develop exhaust gas recirculation modifier data. The exhaust gas recirculation modifier data and basic exhaust gas recirculation data are multiplied ( ) to develop modified exhaust gas recirculation data, and exhaust gas is recirculated in accordance with the modified exhaust gas recirculation data. Using engine speed as a determinant of the extent to which the basic EGR rate should be modified during a fueling transient enables better control over certain exhaust emissions over certain speed ranges.

11/270006

Inventors:

Michael J. McNulty - Lombard IL, US
Christopher R. Ciesla - Palos Heights IL, US
Christopher M. Kaas - Niles IL, US

Assignee:

International Engine Intellectual Property Company, LLC - Warrenville IL

International Classification:

F01N 3/00

US Classification:

60285, 60274, 60276, 60277, 60284

Abstract:

Testing of temperature sensors () in an emission control system, such as in an exhaust system () of a diesel engine, serves to condition further component and/or system testing by determining that sufficient sensor cooling has occurred and that no sensor is “stuck within range” using a strategy ().

US Classification:

60612, 606052, 60611, 123562

Abstract:

A control system for operating vanes of a turbocharger turbine (T) and for operating a turbine-shunting bypass valve () according to a strategy wherein a processor executes an algorithm for selectively unenabling the control system to operate the bypass valve when the control system is operating the vanes to adjust exhaust back-pressure on the engine within a range of effectiveness for the vanes to control the exhaust back-pressure and enabling the control system to operate the bypass valve when the control system has operated the mechanism to a limit of the range of effectiveness.

Appl. No.:

13/641205

Inventors:

Matthew Joseph Seiberlich - Elgin IL, US
Michael James McNulty - Lombard IL, US

Assignee:

Intemational Engine Intellectual Property Company, LLC. - Lisle IL

International Classification:

F02D 41/00

US Classification:

701108

Abstract:

An engine control system () apportions smoke and NOx in engine-out exhaust gas by a strategy () that corrects a target percentage for fresh air and a target percentage for exhaust gas to recalculate a set-point for fresh air mass flow. The target percentage for fresh air mass flow is calculated as a function of engine speed (N) and an engine output torque request (TQI_DRIV).

Appl. No.:

13/877802

Inventors:

Michael James McNulty - Lombard IL, US
Michael A. Makewski - Joliet IL, US

Assignee:

International Engine Intellectual Property Company, LLC - Lisle IL

International Classification:

F02B 47/08
F02M 25/07

US Classification:

12356819

Abstract:

A method of operating an engine is provided. Output of an engine speed sensor, a mass air flow sensor, an exhaust gas temperature sensor, and an engine torque estimator are monitored with an electronic control module. It is determined if the engine is operating in one of either a transient condition and a non-transient condition based upon output of at least one of the sensors and the torque estimator. Fuel injection timing is set based upon if the engine is operating in a transient condition. An exhaust gas recirculation valve position is set upon if the engine is operating in a transient condition. An intake throttle position is set based upon if the engine is operating in a transient condition. The fuel injection timing, exhaust gas recirculation valve position, and the intake throttle position are set to minimize NOx emissions when the engine is operating in a transient condition.

International Classification:

F02D 41/34

US Classification:

123478

Abstract:

A method of controlling a fuel injector is provided. Engine speed is monitored. Engine torque output is monitored. It is determined if the engine speed is within one of a plurality of predefined engine speed ranges. It is determined if the engine torque output is within one of a plurality of predefined engine torque output ranges. One of a plurality of injector coking factors is assigned based on the determined predefined engine speed range and the determined predefined engine torque output range. A total injector coking factor is calculated based upon total operating time within each of the plurality of injector coking factors. A duration of a fuel injection is increased based upon the calculated total injector coking factor.
