[0002] Alcohol hydrogen engine, as the name implies, is an engine that uses alcohol hydrogen as fuel; however, the current alcohol hydrogen engine, the cylinder head and the cylinder body are fixed by bolts. This method of fixing with bolts, when the alcohol hydrogen fuel in the engine is burning, the air pressure in the engine cavity is high, so the force on the bolts is relatively large, resulting in greater wear on the threads, making it difficult to remove the bolts during later maintenance; and due to the effect of air pressure, the bolts are prone to loosening, which is not conducive to the normal operation of the engine and poses a safety hazard. Summary of the invention

[0029] Under the action of the fastening mechanism, the engine block 1 and the engine cylinder head 2 clamp the sealing ring 3.

[0030] The fastening mechanism comprises a circular ring 44 rotatably connected to the engine cylinder head 2, an L-shaped driving rod 45 is welded to the outer wall of the circular ring 44, and an L-shaped locking rod 46 is welded to the outer wall of the L-shaped driving rod 45;

[0031] The fastening mechanism further comprises a locking support block 47 welded to the engine cylinder block 1, and an arc-shaped slide groove 471 is formed on the locking support block 47, and the depth of the arc-shaped slide groove 471 from the center to both sides becomes lower and lower;

[0032] When the L-shaped locking rod 46 contacts the center of the arc-shaped sliding groove 471 , the engine cylinder block 1 and the engine cylinder head 2 clamp the sealing ring 3 .

[0033] A first fixing block 41 and a second fixing block 42 are welded on the engine cylinder head 2. The first fixing block 41 and the second fixing block 42 are symmetrically arranged, and the first fixing block 41 and the second fixing block 42 are rotatably connected to the pin shaft 43 through a bearing. The ring 44 is sleeved on the pin shaft 43.

[0034] When the ring 44 rotates on the pin 43 , the L-shaped locking rod 46 slides in the arc-shaped sliding groove 471 .

[0035] The first fixing block 41 is provided with a first through hole 411 for mounting a bearing, and the second fixing block 42 is provided with a through hole symmetrical to the first through hole 411 and having the same hole diameter as that of the first through hole 411 .

[0036] The ring 44 is provided with a second through hole 441 , and the diameter of the second through hole 441 is equal to the diameter of the pin shaft 43 .
