    • A cylinder liner has reduced wall thickness in a piston pin plane of the liner. A conventional wall thickness of the cylinder liner is maintained in piston thrust plane regions of the liner, where side-to-side motions of a piston reciprocating within the liner tend to produce deflections of the liner, and of a head gasket which bears against the liner. The piston pin plane of the liner is normally orthogonal to the piston thrust plane. The reduced wall thickness affects only external dimensions of the liner; the interior bore of the liner remains fully cylindrical. The exterior of the liner is slightly elliptical, having its minor axis aligned with the plane of the piston pin. The reduced exterior dimension permits an engine designer to reduce engine length due to shortened bore spacing requirements along the piston pin plane, and or to enlarge the space for coolant flow between individual liners.
    • 气缸套在衬套的活塞销平面上具有减小的壁厚。 气缸套的常规壁厚保持在衬套的活塞推力平面区域中,其中在衬套内往复运动的活塞的侧向运动倾向于产生衬套的偏转和头枕头 衬垫。 衬套的活塞销平面通常与活塞推力平面正交。 壁厚减小仅影响衬套的外部尺寸; 内衬的内孔保持完全圆柱形。 衬套的外部略微椭圆形,其短轴与活塞销的平面对准。 减小的外部尺寸允许发动机设计者由于沿着活塞销平面缩短的孔间距要求而减小发动机长度,并且或者扩大在各个衬套之间的冷却剂流动的空间。

    • An apparatus for controlling spillage from a well head or other fluid conducting means comprising a channel member having a fluidic conduit and a dynamic collar surrounding at least a portion of the channel member. The channel member and dynamic collar have a total diameter that is less than the well head or other fluid conducting means diameter. Also disclosed is a method for minimizing fluid spillage from a well head opening or other fluid conducting means opening comprising: a) providing the apparatus of the present invention; b) inserting the device into the opening; c) introducing an expansive material into the dynamic collar to expand the collar sufficiently to seal the opening; and d) optionally, collecting the emerging fluids.
