Abstract
A fuel metering system having a .lambda. regulation device in which the delay periods known per se from the prior art are variable upon the switchover of the integration direction of an integrator included in the .lambda. regulation system. This variation produces a shortening of the delay period, as a result of which it is possible to prevent an excessive enrichment of the mixture. The invention relates to a controllable reduction of the individual delay signal as well as a control of the total duration of control exerted on the delay signals as they appear. The invention is independent of whether it is realized by either analog or digital circuit technology.
