Air/Fuel Mixture: Specifications
With vehicles whose control unit is programmed for operation with an oxygen sensing system and catalytic converter, adaptation of the air/fuel
mixture takes place when the engine is running. This means that the control unit together with the oxygen sensing system compensates deviations from
the programmed injection precontrol by correcting the injection period.
As a result, engine-specific tolerances are corrected when the mixture is being produced. Adaptation of the fuel/air mixture also means that it is not
necessary to adjust the idle CO to a basic setting.
