摘要： A combustion face insert is provided for connection to a bottom wall of an aluminum cylinder head adjacent a combustion chamber in an internal combustion engine which includes an insert body formed of a material having a predetermined hardness. The insert body includes a lower surface facing the combustion chamber and extending radially outwardly to form an outer peripheral extent having a predetermined size necessary to cause the lower surface to be positioned for engagement with an annular combustion seal to effectively seal the combustion chamber. This design allows a greater power density to be achieved in a heavy duty diesel engine utilizing an aluminum cylinder head, increases the thermal fatigue resistance of the valve bridge area and increases the resistance of an aluminum cylinder head to indentation by the combustion seal of the head gasket during deflection of the aluminum cylinder head. Hardened valve seats, which include either a hardened portion of the insert body or a hardened valve seat insert connected to the insert body, are positioned around intake and exhaust openings formed in the insert body for sealing abutment by respective intake and exhaust valves.

摘要： A reinforcing insert for an engine block formed of an engine block material is provided which is positioned in the bearing saddle area of the block for increasing the strength and stiffness of the bearing saddle area to ensure a secure connection of the main bearing cap throughout engine operation thereby ensuring proper crankshaft support and operation. The reinforcing insert is formed of a material having a higher modulus of elasticity than a modulus of elasticity of the engine block material. The insert includes a lower transverse surface for positioning at a lowermost position in the engine block, an upper surface positioned farthest from the crankshaft, a first and second linear side surfaces for positioning on opposite sides of the crankshaft. The linear sides extend from the lower surface along respective planes in nonparallel relation to each other. The linear sides may extend either in a converging or a diverging manner from the lower surface. Alternatively, the insert may include two cylindrical inserts positioned in bores formed in the block on opposite sides of the crankshaft. These insert designs provide strengthening and stiffening of the block over an optimum area while permitting secure attachment of a main bearing cap to the block.
摘要翻译： 提供一种用于由发动机块体材料形成的发动机缸体的加强插入件，其位于该块体的轴承座部区域中，以增加轴承座鞍区域的强度和刚度，以确保主轴承盖在整个发动机运行中的牢固连接 从而确保正确的曲轴支撑和操作。 加强插入件由具有比发动机缸体材料的弹性模量高的弹性模量的材料形成。 插入件包括用于定位在发动机缸体中的最低位置的下横向表面，位于最远离曲轴的上表面，用于定位在曲轴的相对侧上的第一和第二线性侧表面。 线性侧面从相互平行的各个平面的下表面彼此延伸。 线性侧面可以从下表面以会聚或发散的方式延伸。 或者，插入件可以包括两个圆柱形插入件，其位于在曲轴的相对侧上形成在块体中的孔中。 这些插入物设计在最佳区域上提供块的加固和加强，同时允许将主轴承盖牢固地附接到块。

摘要： A reinforcing insert for an engine block formed of a lightweight material is provided which is positioned in the bearing saddle area of the block for increasing the strength and stiffness of the bearing saddle area to ensure a secure connection of the main bearing cap throughout engine operation thereby ensuring proper crankshaft support and operation. The reinforcing insert is formed of a material having a higher modulus of elasticity than a modulus of elasticity of the lightweight engine block material. The insert includes a lower transverse surface for positioning at a lowermost position in the engine block, an upper surface positioned farthest from the crankshaft, a first and second linear side surfaces for positioning on opposite sides of the crankshaft. The linear sides extend from the lower surface along respective planes in nonparallel relation to each other. The linear sides may extend either in a converging or a diverging manner from the lower surface. Alternatively, the insert may include two cylindrical inserts positioned in bores formed in the block on opposite sides of the crankshaft. These insert designs provide strengthening and stiffening of the block over an optimum area while permitting secure attachment of a main bearing cap to the lightweight block.
