ME-Motronic with ETC
The principal function of the engine-man-
agement system is to set the driver’s torque
input whilst at the same time achieving
optimum fuel consumption and the lowest
possible emission level. The ME-Motronic
engine-management system combines
all the sub-systems required for this: The
electronic throttle control (EGAS) sets
the amount of air needed to generate this
torque. The corresponding fuel mass is con-
trolled in the gasoline injection sub-system
and the ignition sub-system sets the appro-
priate ignition point as well as the neces-
sary ignition energy.
In combination with other electronic sys-
tems in the vehicle, the ME-Motronic also
enhances ride comfort and user safety. If,
for example, an ABS or ESP system requires
a specific engine torque to provide vehicle
traction, the ME-Motronic sets the neces-
sary torque.
The sub-systems have become more closely
integrated in order to deal with this wide
range of engine-management tasks. Carbon canister
