摘要：
Methods are disclosed for reducing the variability of particulate emissions in an exhaust stream from an internal combustion engine using a lambda error and/or a NOx error to control an exhaust gas recirculation fraction and/or a mass charge flow control. The methods include operating a controller to adjust the engine gas recirculation fraction and/or the mass charge flow control.
