Requirements of federal and state agencies to control the exhaust emissions of motor vehicles defined performance standards for 1968. Consideration of economics and practicality motivated a full scale design and development program to meet this required performance without the use of a secondary control system. An analysis of new low quench type combustion chambers compared with the standard chambers used on two displacements of a 6-cylinder engine family in prior model years is presented in terms of parameters related to exhaust emission and to conventional engine design.The engine induction system, with special emphasis on carburetor characteristics, is contrasted for application to non-emission controlled engines with application to emission controlled engines.
