This paper outlines the design features of the 4-cyl, overhead camshaft 1.6-liter Dodge Colt engine together with four other single and double overhead camshaft engines in the same family.
These engines have been developed for high performance with a compact size and reduced weight. The Dodge Colt engine, in particular, has been designed to be in compliance with stringent 1972 United States emissions standards.
Emission controls achieved with this engine, such as improved combustion chamber design of small surface/volume ratio and various control systems, are described in some detail.
