Provided is an exhaust purification system for an internal combustion engine. The exhaust purification system comprising: a nox purifying catalyst arranged in an exhaust passage of the internal combustion engine, wherein the nox purifying catalyst comprises a base metal supported on a catalyst support; an oxygen sensor arranged at the downstream side of the nox purifying catalyst in the exhaust passage; and an air-fuel, ratio control means for controlling the air-fuel ratio of exhaust gas flowing into the nox purifying catalyst; wherein when the nox purifying catalyst suffers from predetermined oxygen poisoning, the air-fuel ratio control means controls the air-fuel ratio of the exhaust gas, which flows into the nox purifying catalyst, to a first air-fuel ratio wherein the first air-fuel ratio is richer than a theoretical air-fuel ratio, and then the air-fuel ratio control means switches the air-fuel ratio of the exhaust gas, which flows into the nox purifying catalyst, to a second air-fuel ratio on the basis of an output value from the oxygen sensor wherein the second air-fuel ratio is leaner than the first air-fuel ratio..
|System and method for catalyst heat utilization for gas turbine with exhaust gas recirculation|
A system includes a turbine combustor, a turbine, an exhaust gas compressor, a flow path, and at least one catalytic converter. The turbine is driven by combustion products from the turbine combustor.
|Methods and systems for an exhaust gas treatment system|
Various systems and methods are described for an engine system with an exhaust gas treatment system including a particulate filter. In one example method, accumulated hydrocarbons are removed from the exhaust gas treatment system by increasing an exhaust gas temperature to a first temperature responsive to a particulate filter regeneration request during extended cold idle operation.
|Device and method for an exhaust system of a motor vehicle|
A device for an exhaust system of a motor vehicle includes baffle wall, a passage, and a body having a sidewall with an exhaust conduit extending therethrough. The baffle wall has a bore in fluid communication with the exhaust conduit.
|Coherent-structure fuel treatment systems and methods|
Fuel efficiency in a combustion engine is increased by treating the fuel in a reaction chamber prior to delivering the fuel into the combustion chamber of the engine. The method includes the step of entraining a stream of exhaust gas to travel upstream through the reactor chamber in a first flow pattern.
|Air cooling system and method for a heat recovery steam generator inlet|
The air cooling system and method for a heat recovery steam generator (hrsg) inlet provides a combined cycle power plant utilizing a powerful fan coupled to ductwork connected to pipes that enter the hrsg inlet duct coupled to an exhaust duct of a combustion turbine (ct) for lowering the temperature of the ct exhaust gas provided to the heat recovery steam generator by the ct. The cool air injection system is utilized during low load operation or startup of the ct to ensure that spray water from an inter-stage desuperheater in an hrsg is fully evaporated prior to entering the downstream superheater or reheater.
