The Design Evolution of the Quadrajet Carburetor

This paper describes the technical evolution from contemporary four-barrel carburetors to the new Quadrajet by citing details of construction and their relation to functional requirements. The critical design function recognizes valuable concepts in past practice, optimizes their design, and invents a unified assembly that will best satisfy the future market. The design and its definition must complement new processing techniques in order to achieve maximum quality at reasonable cost. By understanding these engineering principles, it is hoped that the reader will gain a broad viewpoint of carburetor design and be stimulated to establish the proper perspective for further technical growth.
