Abstract
The invention is directed to an arrangement for a fuel metering system for an internal combustion engine. The arrangement includes a computer unit for generating a fuel metering signal in dependence on the operating parameters of the internal combustion engine. The arrangement includes an oxygen sensor and a filter to which the sensor signal is applied, and a subsequent evaluation circuit for additionally influencing the fuel metering signal, preferably in a multiplicative manner. The filter output quantity and engine speed information are utilized together for an additional additive speed-dependent and an additive speed-independent influencing of the fuel metering signal via at least one control function. This arrangement permits a nearly ideal anticipatory control of the fuel metering signal which has an advantageous effect on the engine operating behavior and the exhaust gas quality, in particular with the internal combustion engine in a state of transition and the lambda control circuit deactivated.
