An injection valve 30 is arranged in the intake pipe 20 of the internal combustion engine 15 in order to adjust the value (ON; 1) to the value (ON; 1).
The injection valve 30 is controlled depending on the output signal of the exhaust gas detector 37' disposed in the exhaust gas current of
A time (limit) element 31 is provided for delivering a predetermined output pulse, the duration of the unstable switching (operating) state in said time (limit) element 31 being determined by a limit value switch 36. The limit value switch is configured to be controlled in accordance with the output signal of the exhaust gas detector 37' via an integrator 35 connected upstream of the exhaust gas detector 37.
