Task 

Enriching 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 engine start
• Estimated time after start
• Selector lever position
• Correction programming

Post-start enrichment compensates for the fuel which precipitates on the cylinder walls. The fuel-air mixture is enriched sufficiently until a certain engine speed has stabilized (e.g. 1500 rpm with no gear engaged at +30 °C coolant temperature for about 30 s).
