After-Treatment Component Detection System

View page
US Patent:
8186146, May 29, 2012
Filed:
Aug 27, 2008
Appl. No.:
12/230326
Inventors:
Amit Jayachandran - Peoria IL, US
Mary Lou Kesse - Hanna City IL, US
Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
F01N 3/00
US Classification:
60277, 60274, 60286, 60297, 60311
Abstract:
An after-treatment component detection system may include an exhaust system configured to include an after-treatment component configured to remove one or more constituents of the exhaust gases. The detection system may include an upstream temperature sensor configured to measure temperature upstream from the after-treatment component, a downstream temperature sensor configured to measure temperature downstream from the after-treatment component, and a controller. The controller may be configured to receive signals indicative of upstream temperature measurements from the upstream sensor and signals indicative of downstream temperature measurements from the downstream sensor and determine an upstream rate of temperature change and a downstream rate of temperature change. The controller may also be configured to compare the upstream rate of temperature change to the downstream rate of temperature change and generate a fault if the upstream rate of temperature change and the downstream rate of temperature change differ by less than a predetermined amount.

Integrated Engine And Exhaust After Treatment System And Method Of Operating Same

View page
US Patent:
8209963, Jul 3, 2012
Filed:
May 20, 2008
Appl. No.:
12/154064
Inventors:
Mary L. Kesse - Hanna City IL, US
Wade D. Scrivner - Washington IL, US
Amit Jayachandran - Peoria IL, US
Liangtao Zhu - Dunlap IL, US
Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
F01N 3/00
F01N 3/10
US Classification:
60295, 60286, 60301
Abstract:
An engine system includes an integrated engine and aftertreatment control system via an electronic aftertreatment controller that is in communication with the electronic engine controller. An aftertreatment control algorithm is operable to generate an exhaust control signal and a reductant dosing control signal. The dosing control signal is used to control a flow rate of a reductant (e. g. urea) injection rate into the exhaust system for facilitating a reduction reaction with NOx in the exhaust flow at a suitable downstream catalyst location. The exhaust control signal is communicated to the electronic engine controller, which responds by altering engine operation to change some aspect of the engine exhaust. In one specific example, an ammonia slip event precondition is detected by the electronic aftertreatment controller, and an exhaust control signal in the form of an increase NOx request is communicated to the engine controller, which responds by altering engine operation to increase NOx output in the hopes of preempting the expected ammonia slip event prior to its actual occurrence to maintain undesirable emissions low at the tailpipe.
