49909390 Beginning of regulation of composition of working mix

1. A phase of "the closed regulation chain".
Regulation of composition of working mix begins спутя some time after start of the engine if temperature of cooling liquid is above 10 °C (cars with the mechanical transmission) and 25 °C (cars with the automatic transmission).
2. Phase of "disconnection of a chain of regulation".
At regulation of composition of fuel mix EBU does not consider sensor signal tension size in the following cases:
– when pressing against the stop an accelerator pedal;
– at considerable loadings and high frequency of rotation of a bent shaft;
– at delay if there is information on the released accelerator pedal;
– at failure of the oxygen sensor.
