Abstract
Zur Kühlung eines Vierventil-Zylinderkopfes für ei
nen Viertaktmotor und insbesondere zur Kühlung eines
über dem Brennraum liegenden, einen grossen Material
querschnitt aufweisenden Teils des Zylinderkopfes ist
zwischen dessen Auslass und dessen Einlass ein gerade
verlaufender, zur Auslassseite hin trichterförmig ausge
bildeter und sich in seinem mittleren Teil erweiternder
Durchgang vorgesehen, von dessen mittleren Teil auf
Höhe der Zündkerze eine seitliche, sich nach aussen
hin konisch verbreiternde Ansaugöffnung abzweigt. Hier
bei sind zur Vergrösserung der wärmeabgebenden Flä
che die auslassseitigen Kühlrippen des Zylinderkopfes
wesentlich tiefer ausgebildet als die einlassseitig ange
ordneten Kühlrippen.
