Cold Start Control

OPERATION
During the start phase, fuel is injected several times for each cylinder group per crankshaft revolution. The quantity of fuel is adapted dependent on the engine temperature and the engine speed.

In addition. the ignition timing is shifted in the retard direction the higher the temperature and the lower the start engine speed.

During the initial period after engine start, the initially injected quantity is reduced depending upon the temperature and engine speed in order to avoid an excessively rich mixture. If start is repeated within one minute, the complete initial quantity is no longer injected.

During the warm-up phase, the injection timing and the ignition timing are correspondingly varied also dependent upon engine speed and temperature.

These measures are intended to ensure a lower fuel consumption, good throttle response and smooth engine operation.
