Abstract (en)

[origin: DE4416611A1] The proposal is for a process and device for controlling an internal combustion engine in which a lean fuel-air mixture is supplied in at least a first operating range. When the driver requires more power, e.g. in non-idling operation or in the neighbourhood of full-load running, a stoichiometric mixture is supplied, in which, during the transition, the change in torque owing to the change in the fuel-air mixture is substantially offset by a corresponding adjustment of the air supply to the internal combustion engine.
