Claim 19:
20. A system comprising:
a reductant injection system for injecting reductant into an exhaust gas based on an injection parameter or a supply parameter; and
a controller configured to:
access a current exhaust gas condition parameter and 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,
determine one or more control parameters based on a control model and as a function of the accessed current exhaust gas condition parameter and the accessed current reductant condition parameter, and
modify a value of the injection parameter or the 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 the reductant injection system so as to provide a target spray droplet distribution or a target spray distribution.
