Abstract

Abstract Translated from German 1. Bei bekannten Drallsicheln kann nach dem Gießen des Zylinderkopfes der Drall bzw. die Wirbeldrehzahl des ein­strömenden Gases nicht mehr verändert werden. Die erfin­dungsgemäße Drallsichel soll auch nach der Fertigung des Zylinderkopfes eine leicht zu verändernde Wirbeldrehzahl aufweisen. 2. Erfindungsgemäß ist die Drallsichel (2) abdrehbar ausgebildet. Die Breite (b) der Drallsichel (2) liegt nach dem Gießen des Zylinderkopfes (11) oberhalb des für den gewünschten Dralls erforderlichen Sollwertes. 3. Zylinderkopf einer Brennkraftmaschine 1. In known twist sickles, the swirl or the vortex speed of the inflowing gas can no longer be changed after casting the cylinder head. The swirl sickle according to the invention should also have an easily variable vortex speed after the production of the cylinder head. 2. According to the invention, the twist sickle (2) is designed to be rotatable. After casting the cylinder head (11), the width (b) of the twist sickle (2) is above the desired value required for the desired twist. 3. Cylinder head of an internal combustion engine
