Claim 12:
13. A method comprising:
receiving a signal from an exhaust gas sensor;
determining a current exhaust gas condition parameter based on the signal, wherein the current exhaust qas condition parameter comprises at least one of an exhaust qas pressure, an exhaust qas density, an exhaust qas temperature, an exhaust qas mass flow, or an exhaust qas vorticity;
determining one or more control parameters based on a control model and as a function of the accessed current exhaust gas condition parameter;
modifying a value of an injection parameter or a supply parameter based on the one or more control parameters to control a reductant spray momentum, a reductant droplet momentum, or a reductant momentum vector from a reductant injection system so as to provide a target spray droplet distribution or a target spray distribution; and
commanding the reductant injection system to inject reductant into an exhaust gas based on the injection parameter or a reductant supply system to supply reductant to the reductant injection system based on the supply parameter.
