Aug 21, 2006

Appl. No.:

11/507345

Inventors:

Stephane Cochet - Saint Jean de Braye, FR
Adam Wolf - Cedar Falls IA, US

Assignee:

Deere & Company - Moline IL

International Classification:

F02D 23/00

US Classification:

60602, 606052, 123564

Abstract:

An internal combustion engine is associated with a remote load indicator which provides an output signal, corresponding to an impending increase in mechanical load. The internal combustion engine includes an air supply system and an electrical processing circuit. The electrical processing circuit is coupled with the load indicator and receives the output signal. The electrical processing circuit controls the air supply system to initiate an increase in an air supply to the internal combustion engine prior to the increase in mechanical load.

US Classification:

701108, 7311402, 701103, 7311406

Abstract:

A system for detecting individual cylinder misfire in a multiple cylinder internal combustion (IC) engine having exhaust gas recirculation (EGR). The system includes: a device for predicting EGR flow rate on a cylinder to cylinder basis; a device for sensing actual EGR flow rate on a cylinder to cylinder basis with all cylinders firing; and a device for comparing the predicted EGR flow rate to the actual EGR flow to determine individual cylinder misfire.
