A Feedback Controlled Carburetion System Using Air Bleeds 770352

A feedback controlled carburetion system has been developed that maintains a flow of exhaust gases of uniform composition. This is a requirement if three-way or dual bed catalytic converters are to be used in meeting projected emission standards. Exhaust gas uniformity depends upon delivery of a constant air-fuel ratio by the carburetor. Instead of metering fuel directly, Carter Carburetor finds that precise and responsive control of the air-fuel ratio is obtained by using variable air bleeds in the carburetor fuel circuits.
