ABSTRACT:
A fuel supply system for mixture-comprising, externally ignited internal combustion engines is proposed, which serves to apportion a fuel quantity corresponding to the induced air quantity. The fuel supply system includes an air flow rate meter disposed in the air intake line which actuates a fuel apportionment valve in accordance with the induced air quantity. The restoring force of the air flow rate meter is effected by a control element which is acted upon by pressure fluid, whereby the control element and the pressure control valve each have an air chamber separated from a fuel chamber by a yielding element and in each fuel chamber the same fuel pressure upstream of the fuel apportionment valve and in each air chamber the same pressure in the air intake line upstream of the air flow rate meter prevails as is also effective downstream of the fuel apportionment valve.
