<p>Through the use transfer functions, or other modeling types, directed toward the individual operation of an engine and after-treatment subsystems, an optimizer determines the trade-offs between fuel consumption, urea consumption, and reduction of NOx and PM emissions for each component of the integrated system. Evaluation of these trade-offs permits the optimizer to dictate how each component should be controlled, or adjusted, to achieve optimal fuel (and. urea) consumption while meeting the constraints bounding the solution. Response characteristics can be triggered. by adjusting certain engine operating levers in order to achieve optimal performance of the integrated system.</p> |
