Claim 22:
23. A method comprising:
accessing a current exhaust gas condition parameter;
accessing a current vehicle condition parameter which comprises at least one of a vehicle speed, a vehicle tire pressure, a vehicle inclination angle, a vehicle drive gear selection, a vehicle mass, a vehicle weight, a vehicle trailer weight, or a vehicle air line pressure;
accessing a current reductant condition parameter which comprises at least one of a reductant temperature, reductant momentum based on an injection supply pressure, a reductant density, a reductant air supply pressure, a reductant air supply flow rate, or a reductant spray cone angle;
determining one or more control parameters based on a control model and as a function of the accessed current exhaust gas condition parameter, the accessed current vehicle condition parameter, and the accessed current reductant 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.
