Note:
Via the 02 BLM PART THR., learnt multiplicative deviations from the
ideal mixture (e. g., caused by changes in the air density; changes to the
density and quality of the fuel; injection faults, etc.) are detected by the
control unit and stored in the permanent memory. The learning process only
occurs when oxygen control is active and the engine is operating normally.
The multiplicative correction
factor is effective in the entire characteristic curve range, but
predominantly in the medium and upper engine speed ranges.
Using the 02 BLM PART THR., the values learnt by the
system can be evaluated.
To evaluate a deviation of the 02 BLM PART THR., the 02 INTEGRATOR must be observed.
If this is also outside the
tolerance range, a statement about the engine mixture condition can be made.
