Crankshaft hole.
Specifically, the contact surface of Yu Suoshu main beating cap or/and the main bearing seat opens up a crankshaft oil passage, the crankshaft
Oil duct is connected to the crankshaft hole to the cylinder body main oil gallery.
Specifically, the crankshaft oil passage is opened in the bottom surface of the main bearing seat of the upper cylinder body.
Specifically, the crankshaft oil passage includes that an interconnected cylindrical groove, one first square groove and one second are rectangular
Slot, first square groove are connected to the cylindrical groove to the cylinder body main oil gallery, and the second square groove is connected to the cylindrical groove
To the crankshaft hole.
As a preferred embodiment, the cylindrical groove is cylindrical groove.
As another preferred embodiment, at plane, the side of the cylindrical groove is curved surface for the bottom surface of the cylindrical groove.
The utility model also provides a kind of engine, which includes engine cylinder block as described above.
Compared with prior art, engine cylinder block provided by the utility model, by the way that cylinder body main oil gallery to be moved to down
On cylinder body and upper cylinder body faying face, the draft direction of cylinder body main oil gallery is had changed, the casting technique of cylinder body main oil gallery is simplified；Together
When have changed the draft direction of upper cylinder body faying face main oil gallery and lower cylinder body faying face main oil gallery, the diameter of section of cylinder body main oil gallery
It is not influenced by its length；Upper cylinder body and lower cylinder body assembly rear-bank rotor housing main oil gallery do not need the sealing of bowl-type plug in engine interior,
The bowl-type plug Leakage for avoiding the cylinder body main oil gallery of engine, reduces engine cost.

Specific embodiment
The embodiments of the present invention are described referring now to the drawings, similar element numbers represent similar member in attached drawing
Part.
The utility model is intended to provide a kind of engine and its cylinder block, has that casting technique is simple, cylinder body main oil gallery is cut
Face diameter is not influenced by its length, avoids the advantages of bowl-type plug oil leak.
As shown in Fig. 2 ~ 5, engine cylinder block 120 includes a upper cylinder body 100 and a lower cylinder body 110, upper cylinder body 100
Bottom surface combined with the top surface of lower cylinder body 110, the bottom surface of upper cylinder body 100 offers a upper cylinder body faying face main oil gallery 1, lower cylinder
