Task
Enrich the fuel-air mixture for a short time after a cold start to ensure that the engine runs smoothly.

Design/function
Post-start enrichment is dependent on:
^ Coolant temperature at start
^ Duration after start
^ Selector lever position
^ Correction programming

Post-start enrichment compensates for the fuel which precipitates on the cylinder walls. It is enriched sufficiently until a certain engine speed has stabilized (e.g. 1400 rpm with no gear engaged at +30 °C coolant temperature for about 30 s).
