用于铸造气缸盖的具有隔热间隙的隔热套筒
摘要：
提供了一种铸造气缸盖，其具有由隔热套筒加衬的端口。隔热套筒包括内部套筒，该内部套筒设置在外部套筒内，以在内部套筒和外部套筒之间限定隔热间隙。内部套筒包括入口凸缘表面和出口凸缘表面，其结合于外部套筒的入口凸缘表面和出口凸缘表面，以由此提供经密封的隔热间隙。隔热间隙可包含隔热材料或真空。外部套筒包括外表面，熔融金属铸造到该外表面上以形成铸造气缸。外部套筒的外表面包括肩部，以将隔热套筒固定在铸件内的固定预定位置内。
摘要（英）：

A cast cylinder head having a port lined with an insulating sleeve is provided. The insulating sleeve includes an inner sleeve disposed within an outer sleeve defining an insulating gap between the inner sleeve and outer sleeve. The inner sleeve includes an inlet flange surface and an outlet flange surface joined to an inlet flange surface and an outlet flange surface of the outer sleeve, therebyproviding a sealed insulating gap. The insulating gap may contain an insulating material or a vacuum. The outer sleeve includes an exterior surface onto which a molten metal is casted to form the castcylinder. The exterior surface of the outer-sleeve includes a shoulder to fix the insulating sleeve within a fixed predetermined position within the casting.
