[0034] like Figure 1-9 As shown, in one embodiment of the present invention, a vertical axis engine is provided, comprising a body 10, two oil drain bolts 20 and two oil filling pipes 30. The body 10 has a first side 11 and a second side 12 opposite to each other. Figure 2 The first side 11 is on the right side of the engine body 10, and the second side 12 is on the left side of the engine body 10. A crankshaft cavity is provided within the engine body 10, and two oil drain holes 13 are provided on the engine body 10. The two oil drain holes 13 are connected to the crankshaft cavity, and the two oil drain holes 13 are arranged on the first side 11 and the second side 12, respectively. Two oil drain bolts 20 are threadedly engaged with the corresponding oil drain holes 13. Two oil filler pipes 30 are provided on the first side 11 and the second side 12, respectively, and the oil filler pipes 30 are connected to the crankshaft cavity.

[0035] When the engine oil needs to be added, the user can add the engine oil into the crankcase from the first side 11 or the second side 12 of the engine body 10. When the engine oil needs to be replaced, the user can unscrew the oil drain bolt 20 from the first side 11 or the second side 12 of the engine body 10 to drain the engine oil in the crankcase.

[0036] This embodiment discloses a vertical axis engine. By designing an oil filler pipe 30 and an oil drain bolt 20 on the first side 11 and second side 12 of the engine body 10, respectively, the user can add or drain oil from either side 11 or 12. This allows oil filling and draining operations to be performed independently of the engine's installation location, eliminating the need to move the engine body 10. This solves the maintenance inconvenience associated with conventional vertical axis engines designed with only one side for oil filling and draining, and improves the convenience of subsequent maintenance.

[0037] In one embodiment, in order to facilitate the user to check the oil capacity in the crankshaft cavity, a detachable pipe cover 40 is provided at the pipe mouth of the oil filling pipe 30, and an oil dipstick 50 is inserted and fixed on the pipe cover 40. The oil dipstick 50 passes through the oil filling pipe 30 and extends into the crankshaft cavity.

[0038] In one embodiment, the outer wall of the oil filler pipe 30 at the mouth is provided with two limiting grooves 31 and two notches 32. The limiting grooves 31 extend along the circumference of the oil filler pipe 30 and are arranged symmetrically about the axis of the mouth of the oil filler pipe 30. The notches 32 extend through the end wall of the mouth of the oil filler pipe 30 and communicate with the corresponding limiting grooves 31. The inner wall of the pipe cover 40 is provided with two limiting protrusions 41, which cooperate with the notches 32 and the limiting grooves 31.

[0039] To install the pipe cover 40 onto the oil filler pipe 30, the user simply aligns the two stopper protrusions 41 on the pipe cover 40 with the two notches 32, inserting the stopper protrusions 41 into the stopper grooves 31. The pipe cover 40 is then rotated until the stopper protrusions 41 abut against the wall of the stopper groove 31, away from the notches 32. This structural design ensures a tight fit between the pipe cover 40 and the oil filler pipe 30 and facilitates user operation of the pipe cover 40.

[0040] In one embodiment, the oil filler pipe 30 is integrally formed with a lug 33 having a through-hole 34. The lug 33 on the first side 11 of the oil filler pipe 30 is secured to the starter bracket, while the lug 33 on the second side 12 of the oil filler pipe 30 is secured to the air scoop. The lug 33 on the oil filler pipe 30 ensures a secure fit.

[0041] In one embodiment, the opening of the oil filler pipe 30 is tilted away from the engine body 10. This prevents the opening of the oil filler pipe 30 from being too close to other components of the engine body 10, thereby preventing oil leaking during refueling from adhering to the engine body 10. Furthermore, the tilted oil filler pipe 30 does not excessively occupy the side space of the engine body 10, thereby optimizing the overall structural layout of the engine.

[0042] In one embodiment, the two oil drain holes 13 are staggered. The oil drain hole 13 on the first side 11 is opened on the foot of the oil pan of the engine body 10, and the oil drain hole 13 on the second side 12 is opened on the oil pan of the engine body 10.

[0043] In one embodiment, the bottom of the crankshaft cavity is recessed to form a first groove 14 and a second groove 15. The first groove 14 communicates with the oil drain hole 13 located on the first side 11, and the second groove 15 communicates with the oil drain hole 13 located on the second side 12. The design of the first groove 14 and the second groove 15 facilitates the sedimentation of impurities in the crankshaft cavity, thereby facilitating the discharge of oil from the oil drain hole 13 during oil draining.

[0044] In one embodiment, in order to improve the structural strength of the oil pan of the engine body 10 , a plurality of reinforcing ribs 16 are provided at the bottom of the crankshaft cavity.

[0045] In one embodiment, the outer wall of the engine body 10 is provided with a plurality of heat dissipation ribs 17, which extend to the bottom of the oil pan of the engine body 10. These ribs 17 increase the contact area between the engine body 10 and the air, thereby enhancing the heat dissipation performance of the engine body 10. Furthermore, these ribs 17 can increase the structural strength of the engine body 10, providing it with a certain degree of impact resistance.

[0046] In the specification of the present invention, a large number of specific details are described. However, it is understood that the embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
