Abstract (en)

In a cylinder head for multi-cylinder internal combustion engines with single cylinder heads of cast iron or steel to be fixed on the cylinder block, the single cylinder heads (1) are cast into a common light-alloy outer casing (18). In this way optimum cooling in the critical areas at the base of the cylinder head is achieved, thereby preventing valve seat distortions and suppressing the tendency to knocking in spark ignition engines. <IMAGE>

Abstract (de)

Bei einem Zylinderkopf für mehrzylindrige Brennkraftmaschinen mit am Zylinderblock zu befestigenden Einzylinderköpfen aus Gußeisen oder Stahl, sind die Einzylinderköpfe (1) in ein gemeinsames Mantelgehäuse (18) aus Leichtmetall eingegossen. Dadurch wird eine optimale Kühlung an den kritischen Bereichen des Zylinderkopfbodens erreicht und dadurch Ventilsitzverzüge vermieden und die Klopfneigung bei Ottomotoren hintangehalten. <IMAGE>
