摘要： A cylinder block for an internal combustion engine which, in use, supports a rotary crankshaft 40, the block having pairs of opposed lock width surfaces 37 formed thereon for forming an interference fit with respective co-operating lock width surfaces 38 on the crankshaft bearing caps 34 which in use are secured to respective bearing cap support surfaces 36 also formed on the block 31. The lock width surfaces 37, 38 are spaced from the respective bearing cap support surfaces 36 so as to improve stress cracking resistance of the block 31.
摘要翻译： 一种用于内燃机的气缸体，其在使用中支撑旋转曲轴40，所述块具有形成在其上的成对相对的锁定宽度表面37，用于与曲轴轴承盖上的相应配合的锁定宽度表面38形成过盈配合 34，其在使用中固定到也形成在块31上的相应的轴承盖支撑表面36.锁定宽度表面37,38与相应的轴承盖支撑表面36间隔开，以提高块31的抗应力开裂性。
