Process and Control for Producing Anti-Emission Carburetors

The advent of emission controls for automobiles in California in 1966 triggered a period of expansion in carburetion technology. The industry's design and application engineers have been diligently developing carburetors that satisfy the early California and the 1968 nation-wide emission limits while maintaining performance characteristics. The present paper explains the need for improved carburetor uniformity; describes a program currently in operation to achieve uniformity; and illustrates process changes being generated as a result of the program.
