摘要： A cylinder head for an engine is provided comprising a monolithic structure forming an upper deck, a fire deck, at least one coolant jacket and a cavity to accommodate a fuel injector or an ignitor therein, the cavity defined by a wall connecting the fire deck with the upper deck. The wall connecting the fire deck with the upper deck, as well as other features of the cylinder head, are preferably arranged to support the fire deck against a deflection thereof by transmitting a mechanical load introduced on a flame face of the fire deck to the upper deck. A method of increasing the stiffness of the cylinder head is also provided.

摘要： A hybrid ceramic/sand casting method of manufacturing a metal part. The method is especially suitable for parts having one or more very small internal gaps, such as might occur with a linear passage or round opening. These parts are formed using a hybrid core having at least one ceramic section and at least one sand section, with the ceramic section being used to create the internal gap. A mold cavity is created for the part, and the hybrid core is positioned in the mold. Molten metal is introduced into the mold, and after the metal cools, the core is removed, thereby forming the part with the internal gap.
