PCT No. PCT/DE88/00047 Sec. 371 Date Oct. 4, 1989 Sec. 102(e) Date Oct. 4, 1989 PCT Filed Feb. 2, 1988 PCT Pub. No. WO88/08077 PCT Pub. Date Oct. 20, 1988.In a fuel-metering system for internal combustion engines, the fuel metering is stopped during the overrun operation of the engine and, after overrun cutoff, is increased temporarily with respect to the metering necessary for normal operation and the instantaneous operating point of the engine, in order to accelerate with this fuel enrichment the build-up again of the fuel film in the intake pipe without impairing the composition of the fuel/air mixture. For exact apportioning of the fuel enrichment, the output signal of a lambda probe (21) characterizing the "rich mixture" is used as cutoff criterion for the fuel enrichment.
