GF07.61-P-3011AMG ME-SFI Post-Start Enrichment, Function







After a cold start the fuel-air mixture is enriched for a short time. The fuel which precipitates on the cylinder walls and the intake ports is compensated for by this enrichment and the engine runs smoothly. It is enriched sufficiently until a certain engine speed has stabilized (e.g. 1400 rpm for drive position "P" or "N" and a 30 °C coolant temperature for about 30 seconds).

The post-start enrichment is dependent on:
- Coolant temperature at start
- Combustion cycles (period after start
- Drive position
- Correction programming with STAR DIAGNOSIS
