Method and device for layouts of the discharge of gas in a collector of an internal-combustion engine of an internal combustion engine

摘要

Method and exhaust manifold for damping the pressure oscillations in an exhaust manifold of an internal combustion engine, consisting in throttling the gas flow in the vicinity of the cylinder outlet and then in accelerating the gases flowing in the manifold by providing a uniform flow section in the manifold substantially smaller than that of the cylinder bore.
