G04839890

After a cold start the fuel-air mixture is enriched for a short time to ensure that the engine runs smoothly.

Post-start enrichment compensates for the fuel which has precipitated on the cylinder barrels.

The post-start enrichment is dependent on:

  Fuel injection valve, location/task/design/function   GF07.03-P-5004KE
  Crankshaft position sensor, location/task/design/function   GF07.04-P-4116AM
