=MDFUE Function Description=
The torque msol_w that is to be set on the charge path at base ignition and base efficiency is translated, in torque misopl1_w, which corresponds to the optimum torque for lambda = 1. With the help of the characteristic map [[KFMIRL]] obtain the charge, which is part of this operating point.

This charge is limited to the minimum permissible value rlmin_w, in this case, the idle speed control, the Condition B_mdmin set, which then stops the integrator. In the case of a turbocharger is a limit to the maximum  permissible charge rlmax_w. Naturally aspirated engines that size does not exist!                                                          

Result ones their desired charge rlsol_w.

Addition of application-interface:
<pre>CWRLAPPL = 0:     fct. as before: rlsol generated from the limited KFMIRL.
CWRLAPPL.1    =1: rlsol_w = RLSOLAP
CWRLAPPL.2    =1: rlsol_w = wped_w * FWPEDRLS</pre>

=MDFUE Application Notes=
The map [[KFMIRL]] is inverse to the map [[KFMIOP]] in the section %MDBAS. Application information %MDBAS.
