| 摘要 |
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).
