ABSTRACT:
An air intake manifold comprises a manifold body having a plenum formed with a convexly-curved floor, opposed sidewalls and a radiused inlet which collectively define a plenum interior. A number of air passageways or runners each have an inlet at the plenum interior and an outlet connected to one cylinder of the internal combustion engine where a fuel injector is mounted to combine atomized fuel with the flow of air through such runners. An air guide extends outwardly from the plenum floor in a generally convexly arcuate shape which is effective to smoothly direct the flow of air entering the plenum interior into each of the runners so that turbulence within the runners is substantially reduced thus allowing a maximum amount of air to flow into the cylinders of the engine at both low engine speeds and high engine speeds.
