Abstract

An induction system for a multi valve engine that facilitates operation in a lean burn mode over a large range of speeds and loads by employing a smaller cross sectional branch passages in several induction passages serving a common combustion chamber and a valve arrangement that progressively opens flow first through the branch passages and finally through both the main and branch passages so that maximum power can also be obtained.
