Abstract: Each intake passage of the manifold is divided into two symmetrical passa (3 and 3') which taper gently down toward a restriction (6) beneath the point (7) where fuel is injected. The axes of the two passages converge in V-formation toward the injection point and the division is created by a web (5) incorporated into the initial stage of the intake passage and exhibiting an upturned pear-drop profile when seen in section.
