Abstract
A fuel metering system of an internal combustion engine is regulated by a data processor which has stored data prescribing the proper amount of fuel to be metered out for particular positions of the throttle valve and for particular values of the engine rpm. This preliminary adjustment is further refined by providing the data processor with feedback data concerning actual engine operating parameters, e.g. the exhaust gas composition, engine speed fluctuation and temperature. The feedback data is used by the data processor to override and further adjust the fuel quantity metered out to the engine.
