Abstract
The present application relates to mitigating NOx emissions, and more particularly, to vehicles including a selective catalytic reduction (SCR) system in the exhaust of a diesel or gasoline engine. In one example a method includes temporarily increasing a liquid reductant dosing value injected by an injector from a first dosing value to a second dosing value, the temporary increase in response to a change from injecting liquid reductant onto a first impact location on a disperser device to injecting onto a second impact location on the disperser device.
