摘要： A method of controlling a system having an internal combustion engine, a filter in an exhaust passage, a reduction catalyst downstream of said filter capable of reducing nitrate oxide contained in the exhaust gas with reductant supplied thereto is provided. The method may include, in a first mode, combusting a first amount of particulate matter trapped in said filter and supplying a first amount of reductant to said reduction catalyst when an amount of particulate matter trapped in said filter is less than a predetermined trapping amount (α). The method may further include, in a second mode, combusting a second amount of particulate matter that is greater than said first amount of particulate matter and supplying a second amount of reductant to said reduction catalyst when an amount of particulate matter trapped in said filter is equal to or greater than said predetermined trapping amount (α).

摘要： A system for controlling performance of an internal combustion engine. The system may include an internal combustion engine having an exhaust system for processing gases exhausted from the internal combustion engine. The exhaust system may be comprised of at least one mixing device, at least one emission control device, and a delivery apparatus for delivering an agent affecting operation of the emission control device into the exhaust system. The at least one mixing device may be located downstream of the internal combustion engine and upstream of the at least one emission control device, and the delivery apparatus may be located upstream of the emission control device. The system may include a controller to adjust at least one engine parameter in relation to an operating condition of the mixing device.
