Through the above setting, when the cylinder head cover 1591 is connected to the cylinder head 1592, the sealant at the first position receives the extrusion back, makes the sealant that overflows by the extrusion converge to holding gluey groove 1598 in to promote engine 15's leakproofness, avoid sealed gluey landing to engine 15 in simultaneously, reduce the risk that causes the pollution to engine 15, promoted engine 15's life.
In one implementation, the cylinder head 1592 is coupled to the cylinder block 1593 by fasteners and sealant fit, and the attachment surface 107 is at least partially formed between the cylinder head 1592 and the cylinder block 1593.

Through the above setting, when cylinder head 1592 is connected to cylinder block 1593, the sealed glue of first position receives the extrusion back, makes the sealed glue that overflows by the extrusion converge to holding in the gluey groove 1598 to promote engine 15's leakproofness, avoid sealed glue landing to engine 15 in simultaneously, reduce the risk that causes the pollution to engine 15, promoted engine 15's life.

More specifically, since the second bearing housing 1594e is disposed in the receiving space of the engine 15, when the first position is disposed on the second bearing housing 1594e, the glue receiving groove 1598 may be disposed on one side or both sides of the first position on the second bearing housing 1594e, and at the same time, the glue receiving groove 1598 may be disposed on the same side or opposite sides of the connection surface 107 between the cylinder block 1593 and the crankcase 1594. Specifically, because second bearing frame 1594e sets up in engine 15 accommodation space, when cylinder block 1593 is connected to crankcase 1594, the sealed glue in first position on second bearing frame 1594e receives the extrusion back, can spill over to the both sides of second bearing frame 1594e, all sets up glue containing groove 1598 through the both sides in first position on second bearing frame 1594e to avoid the sealed glue that spills over to slide to in the engine 15, promoted engine 15's life.

In a first predetermined orientation perpendicular to the outer wall of first portion 1596. Wherein the first predetermined direction is shifted along the tangential direction of the first portion 1596 due to the first portion 1596 being an irregular outer wall portion of the outer housing assembly. The glue holding groove 1598 extends along the first preset direction for a first length D1, the first portion 1596 extends along the first preset direction for a wall thickness D2, and a ratio of the length D1 of the glue holding groove 1598 to the wall thickness D2 of the first portion 1596 is greater than or equal to 0.2 and less than or equal to 0.3. Further, a ratio of a length D1 of glue holding tank 1598 to a wall thickness D2 of first portion 1596 is greater than or equal to 0.23 and less than or equal to 0.28. More specifically, the ratio of the length D1 of glue reservoir 1598 to the wall thickness D2 of first portion 1596 is equal to 0.25. Through the above arrangement, the sealant is prevented from overflowing, the risk of pollution inside the engine 15 is reduced, and the service life of the engine 15 is prolonged.
When glue holding tank 1598 is disposed in second portion 1597, glue holding tank 1598 may be disposed on one or both sides of second portion 1597. Among them, the second portion 1597 includes a first bearing housing 1594d, a second bearing housing 1594e, and a third bearing housing 1594f, and the second portion 1597 is not limited to the first bearing housing 1594d, the second bearing housing 1594e, and the third bearing housing 1594f described in this embodiment, and also includes other components provided with a glue receiving groove 1598 in the receiving space. In a second predetermined orientation perpendicular to the inner wall of second portion 1597. Here, since the second portion 1597 is a component disposed in the receiving space of the engine 15, the second preset direction is changed in a tangential direction of the second portion 1596. Glue receiving groove 1598 extends along a second predetermined direction for a length D3 and second portion 1597 extends along a second predetermined direction for a length D4. The ratio of the length D3 of glue holding groove 1598 to the length D4 of second portion 1597 is greater than or equal to 0.2 and less than or equal to 0.42. Further, a ratio of length D3 of glue receiving groove 1598 to length D4 of second portion 1597 is greater than or equal to 0.22 and less than or equal to 0.38. More specifically, the ratio of the length D1 of glue holding tank 1598 to the length D3 of second portion 1597 is equal to or greater than 0.24 and equal to or less than 0.34. Through the setting, the overflow of the sealant is effectively avoided, the risk of pollution inside the engine 15 is reduced, and the service life of the engine 15 is prolonged.
As shown in fig. 13 and 14, as an implementation manner, an end face 1598a of a glue holding groove 1598 is formed on the outer housing assembly 159, and the end face 1598a of the glue holding groove 1598 may be provided in one of the following shapes, or a combination of the following shapes. Wherein, the shape of the end face 1598a of the glue holding groove 1598 may be set as: a plane, an arc surface, a right-angle surface or an irregular curved surface.
When end face 1598a of glue holding groove 1598 is disposed flat, an angle α is formed between end face 1598a of glue holding groove 1598 and the predetermined direction. When face 1598a of glue groove 1598 is configured as an arc, the arc of face 1598a is β. An included angle alpha between the end face 1598a of the glue containing groove 1598 and the preset direction is more than or equal to 0 degree and less than or equal to 90 degrees; the arc β of end face 1598a is greater than 0 ° and less than 180 °. When the end face 1598a of the glue container 1598 is configured as an arc, the arc may be recessed toward the first portion 1596 of the outer housing component 159 or toward the engine 15 receiving space. Through the above arrangement, the sealant is prevented from overflowing, the risk of pollution inside the engine 15 is reduced, and the service life of the engine 15 is prolonged.
It will be understood that modifications and variations are possible to those skilled in the art in light of the above teachings and that all such modifications and variations are considered to be within the purview of the invention as set forth in the appended claims.
