INLET MANIFOLD FOR NORMAL INDUCTION OR SUPERCHARGED INTERNAL COMBUSTION ENGINES FEATURING INDIRECT FUEL INJECTION

摘要

Each intake passage of the manifold is divided into two symmetrical passages (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.
