The map KFLBTS which specifies lambda values as a function of engine speed and
cylinder charge controls enrichment of target lambda. This only activates when
several variables which represent modelled temperatures (a) at the exhaust
manifold, (b) in the catalytic converter, (c) near the catalytic converter (d)
at the cylinder head or (e) near the lambda probe, in a sub-function
LAMBTSENABLE have exceeded their threshold and a start-up delay time has
expired. Apart from the cylinder head temperature which is 200°C, these values
are typically 900-950°C.

Enrichment can be deployed in desired areas, attenuated or eliminated by means
of the map KFFDLBTS (Kennfeld für Faktor Delta Lambdasoll für Bauteileschutz,
map for the multiplication factor for the change in target lambda for component
protection) with units (x,y,z): RPM, % load, multiplication factor.

In addition to LAMBTS, the ATR module controls the general enrichment at high
load and speed (full load enrichment). EGT control is applied only if the
controlled enrichment is insufficient which improves fuel economy. Unlike
LAMBTS which uses modeled temperatures, ATR takes an actual temperature input
from the EGT sensor. The set point for EGT regulation in the ATR function is
given by constant TABGSS (Sollwert Abgastemperatur für
Abgastemperaturregelung).
