The output signals for ignition and injection
are amplified in the control module by integrated
output transistors. The transistors
switching on and off activates the fuel injector
solenoid valves and the primary ignition
coil windings.
The cold-start control works with an actuator
with a worm gear pair that directly actuates
the two throttle valves in the intake
manifold. The control signal is calculated
from the signals of the engine temperature
and from the speed of the crankshaft with
response.
The ideal positions of the throttle valves are
set for all operational states by means of an
adaptive control adjustment maintained by
the control module.

The fuel injectors are small and light weight.
They inject fuel once per crankshaft revolution
in parallel.
To achieve optimal running of the engine
during the start-up and warming phase, fuel
enrichment is provided by activating the
injectors twice as often during starting
phase, then switching over to the once per
crankshaft revolution injection scheme with
a longer ontime to proved enrichment. As
the engine warms the on time is reduced.
When the maximum engine speed of 7000
rpm has been reached, the injection time is
interrupted in order to limit the speed.
