ABSTRACT:
An electronically controlled fuel metering system for an internal combustion engine is proposed which has mixture regulation which can be switched on and off depending upon the operational state of the engine. The system for mixture regulation includes an integrator with an alternating integration direction which can be switched on during steady and quasi-steady operational states. It is further proposed that the integrator time constant be selected in accordance with operating characteristics of the engine and time during the regulation period. For mixture metering, average values are used based on switching values, for instance of a .lambda. sensor in the exhaust pipe. The proposed system is also useable in connection with learning regulating systems, in which corrected values for .lambda.=1 or values for .lambda..noteq.1 computed on that basis and these values then serve as initial values for new regulating cycles.
