Abstract

Bei einem Zylinderkopf (1) eines Kolbenmotors besteht ein wärmeisolierendes Bauteil mit Öffnungen zur Aufnahme von Ventilsitzen, Zündkerzen, Einspritzdüsen aus einer kreis­ förmigen Aluminiumtitanatplatte (2), die in einen flachen und im Zylinderkopf (1) eingespannten oder eingeschrumpften Kreisring (12) aus Zirkonoxid eingeschrumpft ist. Die kreis­ förmige Platte (2) aus Aluminiumtitanat bildet den größten Teil des Zylinderkopfbodens (9). In the case of a cylinder head (1) of a piston engine a heat-insulating component with openings for receiving of valve seats, spark plugs, injectors from a circle shaped aluminum titanate plate (2), which is in a flat and clamped or shrunk in the cylinder head (1) Circular ring (12) is shrunk from zirconium oxide. The circle shaped plate (2) made of aluminum titanate forms the largest Part of the cylinder head base (9).
