Abstract
An electronically controlled or regulated fuel metering system for an internal combustion engine having one sensor each for the air flow in the intake tube and for the throttle valve position is proposed. In accordance with the signals of these sensors, influence can be exerted upon at least one of the operating states of lambda regulation, full load and fuel quantity limitation. The fundamental concept is that not only the air flow rate signal or only the signal relating to an opened throttle valve should be evaluated as a full-load signal but that the full-load state is presumed to exist when, with the throttle valve opened, the air throughput in the intake tube simultaneously exceeds a predetermined value as well. The same condition applies to full-load enrichment. The overall result is cleaner exhaust gas.
