ABSTRACT:
A method of regulating the fuel/air ratio of an internal combustion engine, in which the output voltage of an oxygen measurement probe, located in the exhaust pipe of the engine, is used to regulate the fuel/air ratio in the manner that, upon a sudden change of the output voltage of the oxygen measurement probe, a signal jump takes place which is dependent on the direction of the sudden change, followed then by a change, which is substantilly continuous in time, of a correcting variable for the fuel/air ratio. Under substantially steady-state operating conditions the times of the jumps are controlled independently of the sudden changes in the output voltage of the oxygen measurement probe in the manner that the times between the jumps are smaller than the times between previous sudden changes in the output voltage of the oxygen measurement probe.
