Abstract
A tuned intake manifold is provided for OTTO cycle engines and includes a plenum having an aperture through which a gaseous fuel mixture can be received. First and second branch openings are disposed at opposite points across the plenum, with respective first and second branch conduits connected thereto. Each branch conduit divides into a plurality of runner conduits all terminating at a head flange. The various gaseous paths, each defined by one of the branch conduits and one of the runner conduits, have substantially the same length, substantially the same volume, and substantially the same radius and arc-length of curvature.
