    • Increasing the diameter of cylinder bores in a cylinder block requires a longer and heavier cylinder block to accommodate the larger bores. If the cylinder block is not lengthened it is difficult to accommodate the water jacket between the outermost cylinder bore and the cylinder block end wall. The cylinder block of the present invention has an upper part including a number of cylinder bores surrounded by a water jacket. The upper part also has first and second end walls which are generally co-planar with first and second end walls of a lower part of the block, but include projecting portions adjacent the top deck. The projecting portions may curve outwardly from the first and second end walls and generally follow the curvature of the two outermost cylinder bores on the block. By providing the projecting portions on the first and second end walls, a minimum width of water jacket can be accommodated without significantly increasing the length and overall size of the block.
    • 增加气缸体中的气缸孔的直径需要更长和更重的气缸体以适应较大的孔。 如果气缸体不延长,则难以将水套容纳在最外侧气缸孔和气缸体端壁之间。 本发明的气缸体具有由水套包围的多个气缸孔的上部。 上部还具有第一和第二端壁,该第一和第二端壁通常与块的下部的第一和第二端壁共面,但包括邻近顶层的突出部分。 突出部分可以从第一和第二端壁向外弯曲并且通常沿着块上的两个最外侧的气缸孔的曲率。 通过在第一和第二端壁上设置突出部分,可以容纳最小宽度的水套,而不会显着增加块的长度和总体尺寸。

    • A method of improving the quality of liquid coming from a well that has a pump and pipe assembly. The method includes identifying a region of the well that is low in contamination and a region of the well that is high in contamination, and modifying the pump and pipe assembly so that suction of the assembly is enhanced in the region that is low in contamination and inhibited in the region that is high in contamination. Modifying the pump and pipe assembly can include coupling a suction control device to the pump and pipe assembly, and positioning the suction control device in the region of low contamination. In addition, modifying the assembly can include positioning a flow control disk in a location that is substantially between the region of low concentration and the region of high concentration.
    • 一种改善来自具有泵和管道组件的井的液体的质量的方法。 该方法包括识别污染低的井的区域和污染物高的区域,以及修改泵和管道组件,使得在低污染的区域提高组件的吸力,并且 在污染高的地区受到抑制。 修改泵和管道组件可以包括将抽吸控制装置连接到泵和管道组件,并将抽吸控制装置定位在低污染的区域中。 此外,修改组件可以包括将流量控制盘定位在基本上在低浓度区域和高浓度区域之间的位置。
