Filed:
Dec 27, 2007
Appl. No.:
11/965057
Inventors:
Layne K. Wiggins - Plymouth MI, US

International Classification:
G06F 19/00
F02M 25/07
F02B 75/12
G06F 17/10
US Classification:
701103, 701110, 702182
Abstract:
An engine control system comprises a first factor calculating module that calculates a first factor based on intake cam position (ICAM), exhaust cam position (ECAM), engine speed (RPM) and first calibration factors. A second factor calculating module calculates a second factor based on ICAM, ECAM, RPM and second calibration factors. A residual gas fraction (RGF) estimating module estimates a RGF value based on the first factor adjusted for altitude and said second factor. A method comprises calculating a first factor based on intake cam position (ICAM), exhaust cam position (ECAM), engine speed (RPM) and first calibration factors; calculating a second factor based on ICAM, ECAM, RPM and second calibration factors; and estimating a residual gas fraction (RGF) value based on the first factor adjusted for altitude and said second factor. At least one engine operating parameter is adjusted based on the RGF value.

International Classification:
F02D 41/30
US Classification:
701109, 123672
Abstract:
A fuel control system of an engine includes a simulation module and a control module. The simulation module generates a simulated pre-catalyst exhaust gas oxygen (EGO) sensor signal based on a simulated oxygen concentration of an exhaust gas. The simulation module determines a simulated pre-catalyst equivalence ratio (EQR) for the exhaust gas based on the simulated pre-catalyst EGO sensor signal. The control module generates a desired pre-catalyst EGO sensor signal based on a desired oxygen concentration of the exhaust gas. The control module determines a desired pre-catalyst EQR based on the desired pre-catalyst EGO sensor signal. The control module determines a cost function based on the simulated pre-catalyst EQR and the desired pre-catalyst EQR. The fuel control system is calibrated based on the cost function.

International Classification:
F02D 41/30
F02D 41/00
US Classification:
701109, 123672
Abstract:
A fuel control system of an engine system comprises a pre-catalyst exhaust gas oxygen (EGO) sensor and a control module. The pre-catalyst EGO sensor determines a pre-catalyst EGO signal based on an oxygen concentration of an exhaust gas. The control module determines at least one fuel command and determines at least one expected oxygen concentration of the exhaust gas. The control module determines a final fuel command for the engine system based on the pre-catalyst EGO signal, the fuel command, and the expected oxygen concentration.

Filed:
May 4, 2007
Appl. No.:
11/744495
Inventors:
Byungho Lee - Ann Arbor MI, US
Yann G. Guezennec - Upper Arlington OH, US
International Classification:
G06F 19/00
US Classification:
701 59
Abstract:
A method of mapping and modeling an engine during an engine development process includes testing the engine over a plurality of actual engine operating conditions and gathering actual engine data corresponding to the actual engine operating conditions. A plurality of parameter functions are determined based on the actual engine data, each of the plurality of parameter functions correspond to an engine operating parameter. A plurality of combustion parameters are generated for a plurality of engine operating conditions that include the plurality of actual engine operating conditions and a plurality of virtual engine operating conditions. An engine simulation model is calibrated based on the plurality of combustion parameters and a plurality of engine maps are generated using the simulation model.

Delay Compensation Systems And Methods

US Patent:
8113187, Feb 14, 2012
Filed:
Sep 30, 2009
Appl. No.:
12/570251
Inventors:
Jason Meyer - Dayton OH, US
Shawn W. Midlam-Mohler - Columbus OH, US
Kenneth P. Dudek - Rochester Hills MI, US
Stephen Yurkovich - Columbus OH, US
Yann G. Guezennec - Upper Arlington OH, US
International Classification:
F02D 41/00
F02D 41/02
US Classification:
123703, 701109
Abstract:
A steady-state (SS) delay module determines a SS delay period for SS operating conditions based on an air per cylinder. A dynamic compensation module determines a predicted delay period based on first and second dynamic compensation variables for dynamic operating conditions, the SS delay period, a previous predicted delay period. The first dynamic compensation variable corresponds to a period between a first time when fuel is provided for a cylinder of an engine and a second time when exhaust gas resulting from combustion of the fuel and air is expelled from the cylinder. The SS and predicted delay periods correspond to a period between the first time and a third time when the exhaust gas reaches an exhaust gas oxygen sensor located upstream of a catalyst. A final equivalence ratio module adjusts fuel provided to the cylinder after the third time based on the predicted delay period.

Fuel Control System And Method For Improved Response To Feedback From An Exhaust System

US Patent:
8186336, May 29, 2012
Filed:
Nov 24, 2009
Appl. No.:
12/624779
Inventors:
Jason Meyer - Dayton OH, US
Shawn W. Midlam-Mohler - Columbus OH, US
Kenneth P. Dudek - Rochester Hills MI, US
Stephen Yurkovich - Columbus OH, US
Yann G. Guezennec - Upper Arlington OH, US
International Classification:
F02D 41/00
US Classification:
123695, 123696
Abstract:
An engine control system includes a proportional correction module and a variable proportional gain determination module. The proportional correction module generates a proportional correction for a fuel command to an engine based on a variable proportional gain and a difference between expected and measured amounts of oxygen in exhaust gas produced by the engine. The variable proportional gain determination module determines the variable proportional gain based on a nominal gain and an amount of time since a polarity of the difference has changed, wherein the nominal gain is based on engine operating parameters.

US Patent:
8224557, Jul 17, 2012
Filed:
Jan 14, 2010
Appl. No.:
12/687484
Inventors:
Sai S. V. Rajagopalan - Sterling Heights MI, US
Jason Meyer - Dayton OH, US
Shawn W. Midlam-Mohler - Columbus OH, US
Kenneth P. Dudek - Rochester Hills MI, US
Stephen Yurkovich - Columbus OH, US
Yann G. Guezennec - Upper Arlington OH, US
International Classification:
F02D 41/14
US Classification:
701109, 701103, 123672, 123703
Abstract:
A system includes a cylinder equivalence ratio (EQR) module, a location estimation module, a sensor module, and a fuel control module. The cylinder EQR module determines a first EQR corresponding to a first exhaust gas expelled from a first cylinder and determines a second EQR corresponding to a second exhaust gas expelled from a second cylinder. The location estimation module determines when the first and second exhaust gases mix in an exhaust manifold to form a third exhaust gas having a third EQR. The sensor module estimates an EQR of a fourth exhaust gas based on the third EQR. The fourth exhaust gas is located at an oxygen sensor in the exhaust manifold. The fuel control module controls an amount of fuel supplied to an engine based on a difference between the estimated EQR and an EQR corresponding to measurements from the oxygen sensor.
