CHARGE INTAKE SYSTEM FOR A MULTI-INTAKE VALVE PER CYLINDER ENGINE

摘要

An automotive type fuel injection engine has for each cylinder a single intake manifold runner or log connected by single flow passages to multiple side-by-side intake ports in the cylinder head. A fuel injector is installed in the runner upstream of the dividing portion of the runner. A single constant diameter bore is provided through the cylinder head close to the intake ports intersecting the siamesed flow passages at right angles. The bore contains a one-piece rotatable paddle-like valve with a thin plate in a flow passage, the valve being variable rotatable to close off the passage for fuel economy and power control. The valve is self-contained with sealing and guidance disks. 5868F/88-358
