Procedure to dampen pressure oscillations in the Exhaust manifold of an Engine and the corresponding Manifold

摘要

Procedure to dampen pressure oscillations in the Exhaust manifold of an internal combustion engine with several Cylinders (Certificate of addition of n 466.294 Patent).Wherein the tubular Connecting piece (3) between each Cylinder and the collector (4), configured as a Pipe section or section, presents an effective step of real gases in the neck the vein, whose surface is between 0.6 and 1,7 times the surface area of the theoretical cross section of the pipe section; because the surface of the collector is between 0.6 and 1.7 times the surface area of the theoretical section of the collector; and because the collector has a modular Structure consisting of several sectors. Identical means.
