Engine cylinder block capable of sealing locating type oil tube

The utility model discloses an engine cylinder block capable of sealing a locating type oil tube. The engine cylinder block comprises a cylinder body and a lubricating oil path longitudinally arranged along the cylinder body, and the lubricating oil path is formed by a lubricating oil tube longitudinally penetrating through the cylinder body. According to the engine cylinder block capable of sealing the locating type oil tube, an existing integrated lubricating oil pipeline is replaced by the lubricating oil pipe, leakage of lubricating oil is avoided, sanitary use conditions can be guaranteed, the lubricating oil is saved, and an engine can work normally for a long time; an original lubricating oil path of the cylinder body can be used as a hole path for passing of the lubricating oil pipe, and therefore the engine cylinder block is convenient and simple and saves cost; and meanwhile, the lubricating oil pipe can extend upwards to be matched with a lubricating oil inlet on a cylinder head directly, the effec
