Description of the invention: [Technical field to which the invention pertains] The present invention relates to a water-cooled engine, a steam-red structure, in particular, a type that can enhance the heat dissipation of the head, and an anti-knocking strength of the cylinder head. [Previous technology] According to the general vehicle operation, such as locomotives, all-terrain vehicles, etc., it is to mix the fresh line and fuel imported from the outside I into the oil test, and the county oil and gas input engine generates the power of the explosion. The piston is pushed to reciprocate, and the belt shifting mechanism is driven by the crankshaft to drive, so as to achieve the purpose of traveling. The engine has two types of heat dissipation methods: a sub-domain cold type (four) and a water-cooled engine, among which, the water-cooled type is known. The engine i, as shown in Figures 1 and 2, is mainly composed of a cylinder body 1 1 and a flying cylinder head 12. The cylinder head 12 is provided with a cylinder head 12 above, and the fly red body 1 1 is a piston 14 is provided, the cylinder body 11 is provided with a cold water squirrel σ111 and a cooling water passage 112; a cymbal 13 is disposed between the cylinder body 11 and the cylinder head 12; a cymbal 13 is provided with a perforation 131; the steam red head 12 is provided with - intake passage 121 - an exhaust passage 12 2 having a combustion chamber below the cylinders 1 and 12; and a cylinder head 12 2 further provided with a cooling water outlet 12 3, whereby the cylinder body crucible and the cooling in the cylinder head i 2 The water will heat up to the radiator (not shown) to cool the engine 1. Since the a rainbow head 12 is generally made by casting, the sand core in the cooling underpass 124 is made. It can be discharged smoothly, but will open above the cylinder head 12. Also /3⁄4 stone; /, hole 1 2 5, this sand core can be completed from the sand hole 丄 2 5, and then H piece 2 The correction hole 1 2 5 is shouted to form a cooling water passage 124 for the cooling water to flow. The conventional steam head 丄 2 can be cooled by the cooling water passage 12 4 . However, as I am It is known that the engine 丄 红 red head 1 2 must be provided with at least three perforations communicating with the combustion chamber 丄 5 for the passage of the spark plug 16, the intake valve 17 and the exhaust 丄 8 respectively. 1 = The powertrain uses her oil to ignite in the combustion chamber. After the explosion, the fuel is generated by the blasting force. Therefore, when the fuel is in the combustion chamber 丨5 After the explosion, its blasting power is divided by the α push = base 14 > the combustion chamber 丨 5 of the head 12 is also subject to the pressure of the fuel blasting force. Therefore, the cylinder 2 is the cooling water passage 124 to the combustion chamber 1 $ = The thickness of il 2 6 thick directly affects the anti-knock strength of steam (four) and 丨 2. The wall between the cold water channel of the raft head 1 2 4 and the combustion chamber 1 5 is thicker. At the same time, although the anti-knocking strength of the new head 1 2 can be increased, it is also due to the thick thickness of the wall 1 2 6 and the poor cooling of the cylinder head i 2, thereby reducing the durability of the cylinder H2; When the wall 1 2 6 冷却 between the cooling water passages 24 to 1 15 of the head i 2 is implemented, although the heat dissipation of the steam red head 12 can be improved, the anti-knocking of the steam and the 丨 2 is caused. The strength is greatly reduced', so it is very easy to cause the spark plug 16, the intake valve 17 and the exhaust gas to be lost. This will cause the airtightness of the air inlet 27 and the exhaust valve 丄8 to be lost. The heavyweights will also make the Mars plug 16, the intake valve 17 and the exhaust unit U component coffee rhyme (4) i 2 Hall Qing shock intensity, "° structure, is an important issue for the locomotive industry to be solved. 1343448 [Summary of the Invention] In order to solve the problem of (4) the failure of the Shantou to be able to combine the strength and the anti-knocking strength, the purpose is to improve the cylinder-shaped bulk ship and improve the cylinder resistance and strength. 'The main miscellaneous section of the present invention is providing a cold type?丨 汽缸 cylinder head community 'refinement less package wealth - steam _, - cylinder core, the fine head has a cooling water channel, the secret head at least three perforations connected to the machine room to separate the Mars , the money exhaust valve is worn, and the cooling water passage of the other cylinder head • at least one sand hole is opened above, and the sealing element is sealed on the sand hole, the main reason is that: the lower end of the element is extended in the direction of the chamber An extension section is provided, and the extension section of the closed jaw is disposed at a partition wall between the cooling water passage of the cylinder head and the combustion chamber, thereby improving heat dissipation of the cylinder head and improving the knocking strength of the cylinder head .
