An apparatus, system, and method are disclosed for reducing nitrogen oxide
emissions in a combustion engine. The method includes a shift detection
module determining an out of gear (OOG) indicator for a manual
transmission. The method further includes an engine speed module
determining an engine speed target based on at least one operating
condition of the engine. The method continues with a load determination
module determining an engine load target in response to the OOG indicator
and an engine acceleration module determining a desired net torque based
on the engine speed target and the engine load target. Finally, the
method concludes with an emissions module determining a minimum fuel
target based on the desired net torque and an actuation module generating
a fueling signal to engage an engine fueling.
