Claim 0:
1. 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, which comprises at least one of an exhaust gas pressure, an exhaust gas density, an exhaust gas temperature, an exhaust gas mass flow, or an exhaust gas vorticity,
determine one or more control parameters based on a control model and as a function of the accessed current exhaust gas 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.
