ABSTRACT:
A flow duct, particularly an intake duct in an intake system and a cylinder head of an internal-combustion engine has a defined flow profile by means of which the flow rate of the gas flow is accelerated continuously, specifically until it reaches a cross-sectional transition area of the intake duct which--viewed in the flow direction--is situated upstream of a valve stem. After that, the flow rate of the gas flow is reduced whereby a lower approach flow speed of the valve is achieved. This causes an optimized volumetric efficiency which has a favorable effect on the power and the consumption of the internal-combustion engine.
