US Patent:

6347519, Feb 19, 2002
Filed:

Aug 17, 2000
Appl. No.:

09/641256
Inventors:

Admir M. Kreso - Northville MI
Assignee:

Detroit Diesel Corporation - Detroit MI
International Classification:

F02D 2300
US Classification:

60602, 606052
Abstract:

A system and method for measuring the flow rate of recirculated exhaust gas in a compression ignition engine including a plurality of engine sensors having outputs indicative of current engine conditions and a turbocharger. The system includes an exhaust gas recirculation (EGR) valve mounted in the exhaust pipe upstream of the turbocharger for diverting a selectable portion of the exhaust gas for recirculation and combination with the charge air, one or more sensors for sensing current conditions of the recirculated exhaust gas, including temperature and pressure, one or more sensors for sensing current conditions of the intake air, and control logic for determining the flow rate of the recirculated exhaust gas as a function of the sensed conditions. In one embodiment, the system includes an obstruction in the flow path of the recirculated exhaust gas and a differential pressure sensor for determining the pressure differential between a point upstream of the obstruction and a point downstream of the obstruction and control logic for determining the flow rate of the recirculated exhaust gas as a function of the current intake manifold pressure, the recirculated exhaust gas temperature, and the differential pressure drop across the obstruction.

US Patent:

7076953, Jul 18, 2006
Filed:

Sep 19, 2002
Appl. No.:

10/474883
Inventors:

Admir Kreso - Canton MI, US
Assignee:

Detroit Diesel Corporation - Detroit MI
International Classification:

F02B 33/44
US Classification:

606052, 12356811, 12356821
Abstract:

A method for controlling an internal combustion engine is provided. The engine includes a variable geometry turbocharger (VGT) system and an exhaust gas recirculation (EGR) system. In a boost mode, the VGT system is controlled with a closed loop based on boost pressure. In an EGR mode, the VGT system is controlled with a closed loop based on EGR rate. Further, in the EGR mode, the EGR system is controlled with a closed loop based on boost pressure. Preferred control techniques are also provided including non-linear compensation and adaptive feed forward control.

US Patent:

7461504, Dec 9, 2008
Filed:

Dec 21, 2004
Appl. No.:

11/018314
Inventors:

Oliver A. Warner - Brighton MI, US
Admir Kreso - Canton MI, US
Michael A. Balnaves - Canton MI, US
Assignee:

Detroit Diesel Corporation - Detroit MI
International Classification:

F01N 3/00
US Classification:

60286, 60274, 60295, 60300, 60311, 123 9015
Abstract:

Method, system, and controller for controlling exhaust gas temperatures by adjusting exhaust valve timing and/or fueling for one or more cylinders wherein normal operating cylinders receive additional fuel to compensate for the adjusted cylinders, thereby increasing exhaust gas temperatures. The method, system, and controller may be applicable in systems having an engine which emits exhaust gases having particulates which are captured by the particulate filter.

Filed:

Mar 10, 2005
Appl. No.:

11/076718
Inventors:

Ravishankar Ramamurthy - Westland MI, US

Admir Kreso - Canton MI, US
Assignee:

Detroit Diesel Corporation - Detroit MI
International Classification:

F02D 23/00
F02B 33/44
US Classification:

060602000, 060605200
Abstract:

A method for controlling exhaust gas particulate emissions from a compression ignition internal combustion engine having a variable geometry turbocharger (VGT) includes the steps of determining backpressure across the engine and air mass flow into the engine, closing vanes of the VGT to provide air mass flow increase when backpressure is increasing, and stopping the step of closing the vanes of the VGT when a decrease in rate of change of air mass flow is determined.

Abstract:

A method to operate an electronically controlled air compressor powered by an internal combustion engine, wherein the air compressor is selectively activated when the air compressor minimum threshold value differs from the air compressor minimum threshold hysteresis by a predetermined value, and is deactivated when the air compressor maximum threshold value and the air compressor maximum threshold value hysteresis value differ by a predetermined value.

US Patent:

63051672, Oct 23, 2001
Filed:

Mar 31, 2000
Appl. No.:

9/540017
Inventors:

Steve Miller Weisman - Farmington Hills MI
Admir Kreso - Canton MI
Andrew May - Ann Arbor MI
Assignee:

Detroit Diesel Corporation - Detroit MI
International Classification:

F02B 3724
F02M 2507
US Classification:

60602
Abstract:

A method of controlling an internal combustion engine includes determining an exhaust gas recirculation (EGR) command signal based on at least one engine condition, and determining a variable geometry turbocharger (VGT) command signal based on at least one engine condition and at least partially based on the EGR command signal. Advantageously, the EGR system and VGT system may be continuously and simultaneously controlled, taking into account the effects of each system on the other, to provide improved and more precise control over engine air flow. In an alternative embodiment, an engine may be controlled with a feedback control system where engine intake chemical composition is the feedback variable.
