Automotive Engine Having Catalytic Exhaust Aftertreatment Device And Secondary Air Injection Control System For Minimum Catalyst Light-Off Time
US Patent:
5410872, May 2, 1995
Filed:
Oct 4, 1993
Appl. No.:
8/131222
Inventors:
Andrew A. Adamczyk - Dearborn MI
Clifford N. Montreuil - Dearborn MI
Scott C. Williams - Dearborn MI

Assignee:
Ford Motor Company - Dearborn MI
International Classification:
F01N 320
US Classification:
60274
Abstract:
An automotive engine and exhaust aftertreatment system includes an engine, a catalytic exhaust aftertreatment device for receiving exhaust gas from the engine, and an air source for supplying air to the exhaust stream entering the catalyst. An exhaust gas oxygen sensor determines the amount of oxygen contained in the exhaust entering the catalyst, and an engine control computer connected with the air source and with the oxygen sensor monitors the amount of oxygen contained in the exhaust and controls the amount of air supplied to the exhaust stream by the air source such that the available oxygen is slightly in excess of the stoichiometric requirement. In this manner, the light-off time of the catalyst is minimized.

International Classification:
F01N 300
US Classification:
60274
Abstract:
A catalytic converter having a first highly loaded palladium or trimetal catalytic element containing palladium of relatively large particle size closely coupled to the engine exhaust manifold, followed by one or more second catalytic elements having high oxygen storage capacity to provide protection against warmed-up engine emissions break through, is efficient in reducing cold-start emissions through early catalyst light-off. The catalytic converter is advantageously used in conjunction with an engine strategy employing oscillative spark retard during warm up to further reduce catalyst light-off and transient spark advance dampening to eliminate spiking of HC and CO during engine transients. When employed in conjunction with secondary air injection, the engine EEC is programmed to delay air injection for a period following cold-start sufficient to assure that catalyst light-off is rapidly attained.

International Classification:
F01N 3/023
US Classification:
60274, 60277
Abstract:
Systems and methods for controlling regeneration of a diesel particulate filter in a vehicle engine exhaust include detecting a distance of an object from the exhaust and controlling a regeneration event if the distance is less than a threshold value. The system and method may include a particulate filter disposed in the exhaust of the vehicle and a proximity sensor disposed adjacent an exhaust opening and positioned to detect presence of an object near the opening. A controller in communication with the proximity sensor is adapted for controlling regeneration of the particulate filter in response to the proximity sensor detecting the object near the opening.
