Method And Apparatus For Reducing Combustion Engine Emissions
View pageUS Patent:
20030209007, Nov 13, 2003
Filed:
May 10, 2002
Appl. No.:
10/142343
Inventors:
Anthony Furman - Scotia NY, US
Michael Cueman - Niskayuna NY, US
Penelope Markatou - Phoenixville PA, US

International Classification:
F01N003/00
F01N003/10
F01N003/10
US Classification:
060/275000, 060/300000
Abstract:
An apparatus for reducing emissions of a combustion engine is disclosed, the apparatus comprising: an energy converter adapted to convert mechanical energy to electrical energy, but having no mechanical coupling to any drive shaft of the combustion engine; and an exhaust aftertreatment device adapted to receive the electrical energy from the energy converter, receive exhaust gases from the combustion engine, and remove pollutants from the exhaust gases.

Abstract:
An exhaust gas purification system for lowering the content of impurities in a lean exhaust gas of an internal combustion engine comprising, a feeding device that feeds ammonia or a compound decomposable to ammonia into an exhaust gas stream containing nitrogen oxides; a selective catalytic reduction catalyst comprising vanadium (V-SCR catalyst) which catalyzes the nitrogen oxides with ammonia in a temperature range of about 150 C. to about 400 C. and at an NO/NOratio of about 0.3 to about 0.9; and a downstream system comprising a diesel oxidation catalyst.

Assignee:
JOHNSON MATTHEY PUBLIC LIMITED COMPANY - London
International Classification:
G01N 21/78
B01D 53/94
B01D 53/94
Abstract:
A diagnostic system for an exhaust system of an internal combustion engine is disclosed. The diagnostic system comprises a catalyst component and a marker that undergoes a physical transition above a transition temperature of the marker. A method for determining if a catalyst component in an exhaust system for an internal combustion engine has been exposed to a deactivating temperature is also disclosed.

Abstract:
Provided is a catalytic article comprising (a) a flow through honeycomb substrate having channel walls; (b) a first NH-SCR catalyst composition coated on and/or within the channel walls in a first zone; and (c) a second NH-SCR catalyst composition coated on and/or within the channel walls in a second zone, provided that the first zone is upstream of the second zone and the first and second zones are adjacent or at least partially overlap; and wherein the first NH-SCR catalyst comprises a first copper loaded molecular sieve having a copper to aluminum atomic ratio of about 0.1 to 0.375 and the second NH-SCR catalyst comprises a second copper loaded molecular sieve having a copper-to-aluminum atomic ratio of about 0.3 to about 0.6.
