Abstract: The present invention concerns an engine block (1) of a metal material for a multicylinder internal combustion engine, with a housing (2), in which cylinder boreholes (5) are provided, whereby the outer surfaces of side walls (6) of cylinder boreholes (5) are distanced from the wall (3) of housing (2), so that cooling channels (9) arranged between wall (3) and cylinder boreholes (5) result. It is provided according to the invention that cylinder boreholes (5′) are shortened such that the height (h2) of the shortened cylinder boreholes (5′) is smaller than the height (h1) of the unshortened cylinder boreholes (5). The present invention also concerns a cylinder bushing (10) with a sleeve (11) and a collar (12), whose outer diameter is larger than the outer diameter of sleeve (11).

Abstract translation: 本发明涉及一种用于多缸内燃机的金属材料的发动机缸体（1），其具有壳体（2），其中设有气缸钻孔（5），由此缸体的侧壁（6）的外表面 钻孔（5）与壳体（2）的壁（3）分开，从而导致布置在壁（3）和气缸钻孔（5）之间的冷却通道（9）。 根据本发明提供的是，气缸钻孔（5'）被缩短，使得缩短的气缸钻孔（5'）的高度（h2）小于未启动的气缸钻孔（5）的高度（h1）。 本发明还涉及一种具有套筒（11）和轴环（12）的气缸衬套（10），其外径大于套筒（11）的外径。
