Abstract
A fuel metering system for an internal combustion engine meters out fuel in dependence on the pressure in a fuel supply container. This pressure is controlled by a valve or valves which provide communication with different regions of the induction tube of the engine. The control valves are electro-magnetic valves under the control of a suitably processed and amplified signal from an exhaust gas measuring probe which determines the concentration of oxygen.
