Abstract
The utility model relates to a double cooling engine, which includes a cylinder housing, a cylinder sleeve and a cylinder radiating sleeve, wherein a cooling water circulation cavity is arranged in the cylinder housing; a technical opening corresponding to the cooling water circulation cavity and a sealing cover capable of sealing the technical opening are arranged on the side surface of the cylinder housing. The utility model is characterized in that a cylindrical boss is arranged on the sealing cover, a water cooling passage is arranged in the boss, a water passing opening communicated with the water cooling passage is formed on the end surface of the boss, and the facing direction of the water passing opening is vertical to the facing direction of the through hole in the cylinder sleeve. By adopting the technical scheme, the double cooling engine has the advantages of simple structure, economy, durability and long service life, and can increase the radiating area of the sealing cover and improve the radiating effect of the engine cylinder.
Description
Technical field
The utility model relates to a kind of motorcycle engine.
Background technique
Existing pair of cold engine comprises crankcase, cylinder block and cylinder head, and the side of cylinder head is provided with the mouth of a river of crossing that communicates with cooling water chamber, is communicated with the water cycle cooling channel of motor through crossing the water nozzle that is provided with on the mouth of a river; Carry out the water cycle cooling; The water nozzle of crossing on the mouth of a river makes cooling water shorter in cylinder head side flow distance, and the water-cooled area of cylinder head side is less, and its heat diffusion area is little; Radiating effect is relatively poor; Can the radiating effect of cylinder head be exerted an influence, the intensity of water nozzle is lower, and working life is short.The side of cylinder block is provided with the sealing cover with corresponding technology opening of cooling water chamber and ability sealing technology opening; And the water-cooled area of the sealing cover on the cylinder block is also less, and its heat diffusion area is little, and effect is relatively poor; Working life is short, can the radiating effect of cylinder shell be exerted an influence.The above-mentioned cylinder head and the radiating effect of cylinder block will directly influence the radiating effect of motor.
The model utility content
The purpose of the utility model just provides a kind of two cold engines of simple in structure, long service life, and it can increase the heat diffusion area of cylinder head, improves the radiating effect of motor.
The purpose of the utility model is to realize through such technological scheme; It comprises crankcase, cylinder block and cylinder head; Be provided with cooling water chamber in cylinder block and the cylinder head, it is characterized in that: the side of cylinder head is provided with circular pylon, in circular pylon, offers the water channel of crossing that communicates with cooling water chamber; One end of circular pylon has and crosses the mouth of a river of crossing that water channel communicates, and the middle part of circular pylon is provided with the pair that communicates with the mistake water channel and crosses the mouth of a river.
The side of the utility model cylinder head be provided with the circular pylon of water channel, make cooling water in the cylinder head side flow apart from growth, through crossing the mouth of a river and the secondary mouth of a river of crossing; Make current even, radiating effect is remarkable, and the water-cooled area of cylinder head side increases; Heat diffusion area obtains increasing, and has improved radiating effect, has improved the whole radiating effect of motor; The intensity of circular pylon is higher, has prolonged working life, and is easy to process.
Owing to adopted technique scheme; The utlity model has the advantage of simple in structure, economy and durability and long service life; It can increase the heat diffusion area of cylinder block and cylinder head, improves the radiating effect of cylinder block and cylinder head, thereby has improved the whole radiating effect of motor.
