Abstract
The utility model belongs to the technical field of cooling and relates to an air cooled motorcycle engine cylinder head. The air cooled motorcycle engine cylinder head comprises a combustion chamber (7) with a cylinder head intake duct (2) and a cylinder head exhaust duct (5) symmetrically arranged on two sides, wherein cylinder head fastening bolt holes A (1), B (3), C (4) and D (6) are uniformly formed on the circumference of the combustion chamber (7); the four cylinder head fastening bolt holes A (1), B (3), C (4) and D (6) are symmetrically distributed on two sides of the central plane of the intake duct (2) and the exhaust duct (5); and four cooling passages are formed between the outer walls of the four cylinder head fastening bolt holes A (1), B (3), C (4) and D (6) and the outer walls of the intake duct (2) and the exhaust duct (5). The cylinder head is cooled by use of the four cooling passages, which takes full consideration of the air flow surrounding the engine cylinder head of the motorcycle during the operation, thereby achieving good cooling effect.
Description
Technical field
The utility model belongs to the cooling technology field, relates to a kind of air-cooled motorcycle engine cylinder head.
Background technique
The motorcycle engine cylinder head has two kinds of air-cooled and water-cooleds, and air-cooled cylinder head is provided with radiator shutter around in the firing chamber, and engine cooling is to take away heat by air flows from radiating fin; The water cooled cylinder head is provided with cooling jacket on every side in the firing chamber, engine cooling is to flow by water cycle to take away heat from chamber wall.No matter be air-cooled cylinder head or water cooled cylinder head, all will consider cooling effect, can not cause engine overheat.The air-cooled cylinder head of existing motorcycle engine is because the restriction of process structure aspect, intake and exhaust port is not to be symmetrically distributed in the both sides, firing chamber, generally only be provided with one, two or three air ventilation cooling channels, thereby can not reach cooling heat dissipation effect preferably.
Summary of the invention
The purpose of this utility model is to propose a kind of air-cooled motorcycle engine cylinder head, makes it can take into full account motorcycle the flowing of engine cylinder head surrounding atmosphere when operation, to reach better cooling effect.
The utility model is to finish the technological scheme that the invention task adopted to be: a kind of air-cooled motorcycle engine cylinder head, have the firing chamber in the described cylinder head, and the bilateral symmetry in described firing chamber is provided with cylinder head intake duct and air outlet flue; Around described firing chamber, evenly be provided with cylinder head fastening screw keyhole, and described four cylinder head fastening screw keyhole A, B, C, D are symmetrically distributed in the both sides of intake duct and air outlet flue central plane; Constitute two cooling channel A, B between the outer wall of the outer wall of described air outlet flue and its both sides cylinder head fastening screw keyhole A, B; Constitute two cooling channel C, D between the outer wall of the outer wall of described intake duct and its both sides cylinder head fastening screw keyhole C, D, and cooling channel A, the B of the outer wall both sides of intake duct are connected with cooling channel C, the D of the outer wall both sides of air outlet flue.
A kind of air-cooled motorcycle engine cylinder head that the utility model proposes adopts four cooling channel cooling air cylinder heads, taken into full account motorcycle the flowing of engine cylinder head surrounding atmosphere when operation, reached better cooling effect.
Description of drawings
Fig. 1 is the plan view of motorcycle engine cylinder head described in the utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the worm's eye view of Fig. 1.
Among the figure: 1, cylinder head fastening screw keyhole A, 2, air outlet flue, 3, cylinder head fastening screw keyhole B, 4, cylinder head fastening screw keyhole C, 5, intake duct, 6, cylinder head fastening screw keyhole D, 7, the firing chamber, 8, cooling channel A, 9, cooling channel B, 10, cooling channel C, 11, cooling channel D.
Embodiment
Now in conjunction with the accompanying drawings the utility model is described in further detail;
As shown in Figure 1 to Figure 3: a kind of air-cooled motorcycle engine cylinder head, have firing chamber 7 in the described cylinder head, the bilateral symmetry in described firing chamber 7 is provided with cylinder head air outlet flue 2 and intake duct 5; Around described firing chamber 7, evenly be provided with cylinder head fastening screw keyhole A1, B3, C4, D6, guarantee that cylinder head is installed in the sealing on the motor; And described four cylinder head fastening screw keyhole A1, B3, C4, D6 are symmetrically distributed in the both sides of intake duct 2 and air outlet flue 5 central planes; Constitute two cooling channel A8, B9 between the outer wall of the outer wall of described air outlet flue 2 and its both sides cylinder head fastening screw keyhole A1, B3; Constitute two cooling channel C10, D11 between the outer wall of the outer wall of described intake duct 5 and its both sides cylinder head fastening screw keyhole C4, D6, and cooling channel A8, the B9 of the outer wall both sides of air outlet flue are connected with cooling channel C10, the D11 of the outer wall both sides of intake duct.When motorcycle moves, air outlet flue 2 outlets are the windward sides in the motorcycle running, intake duct 5 imports are lee faces, air enters 7 tops, firing chamber from outer wall both sides cooling channel A8, the B9 of air outlet flue 2, take away the heat that distribute the firing chamber, outer wall two leading side winds from intake duct 5 flow out then, and the air flows situation is shown in arrow among Fig. 2.
