Abstract

As a means of providing improved control of the air-fuel ratio to an internal combustion engine for, in turn, maintaining control of the exhaust gas properties there is a regulation of fuel input responsive to a pressure exerted on the fuel in the carburetor float chamber. Sensing means are provided to be responsive to ambient conditions and/or to a given exhaust gas component. Such sensors, along with transmitter means, are integrated into the system to have fuel flow increased or decreased by pressure in the float chamber proportional to the net effect of having an increasing or decreasing quantity of O2 present.
