Abstract
An intake port for an internal-combustion engine is composed of an inlet duct which is constructed in the cylinder head and has a more curved section close to the combustion space and a flat or less curved section away from the combustion space. The inlet duct is adjoined by an intake connection piece which is fastened to the cylinder head and is connected wit the intake system. In the intake port formed of the intake connection piece and the inlet duct, a guiding device is constructed which is arranged in the inlet duct and extends into the more curved area of the inlet duct. The guiding device includes a movable section to differently guide the inlet duct flow as a function of engine operating conditions.
