Abstract
An improved intake manifold and plenum construction for an electronic fuel injected engine. The manifold includes a plurality of parallel runners, with each runner having a lower end communicating through a port in the cylinder head with a cylinder of the engine, and an open upper end. A fuel injector is mounted in each runner for injecting fuel into the runner. A plenum is mounted on the manifold and includes an upper wall and a lower wall which is spaced from the upper wall to define an air chamber, The upper ends of the runners communicate with the chamber, so that air is drawn from the chamber through the runners to the cylinders. A flange is spaced from the upper end of each runner, and the lower wall of the plenum is supported on the flanges so that the upper end of each runner projects into the plenum chamber, Hollow posts extend between the upper and lower walls of the plenum and bolts extend through the hollow posts and are threaded into the flanges on the runners to connect the plenum to the manifold.
