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).
