Description
Technical field
The utility model relates to the improvement of motorcycle engine cylinder head structure.
Background technique
The motorcycle engine cylinder head is the important component part of motor, and the effect of cylinder head is except that sealing cylinder, and the calixconcavity of cylinder head bottom surface part constitutes the firing chamber jointly with piston and inboard wall of cylinder liner, and parts such as spark plug are installed on cylinder head.Engine cylinder head directly bears high temperature, the high pressure of combustion gas, and therefore good heat dissipation design is the prerequisite of engine cylinder head reliably working.In order to improve the heat dissipation potential of cylinder head, the cylinder head outside is cast with an amount of radiating fin.Engine cylinder head inner ad hoc cooling duct is also arranged, but existing cylinder head is single cooling duct, intake grill is located at the windward side, exhaust outlet is positioned at by the spark plug, outside existing cooling duct decapacitation is cooled off the firing chamber, spark plug also there is certain cooling effect, but limited to the cooling effect of firing chamber.Simultaneously, the available engine cylinder head mostly is single spark plug design, and is abundant relatively inadequately from the inflammable mixture burning that spark-plug location is far away, can increase oil consumption and discharging.
The model utility content
At the prior art above shortcomings, the purpose of this utility model provides a kind of motorcycle engine cylinder head that can cool off, improve burning, reduction discharging better to engine cylinder head.
The technical solution of the utility model is achieved in that a kind of motorcycle engine cylinder head, be provided with space curved surface at the cylinder head bottom surface, on cylinder head, be provided with suction port, relief opening, spark-plug hole and cooling duct, suction port, relief opening and spark-plug hole are located on this space curved surface, it is characterized in that: described cooling duct is twice, the intake grill of two cooling ducts lays respectively at the relief opening both sides, is provided with the exhaust outlet of cooling duct in the suction port both sides.
Described spark-plug hole is two that are oppositely arranged, and spark-plug hole both sides are provided with the cooling duct exhaust outlet therein.
Described cylinder head is provided with cylinder head cover, is provided with stiffening rib in the cylinder head cover.
Described space curved surface is formed by air inlet sphere that varies in size and exhaust spheres intersect, and the arc surface transition is adopted in the intersection, and suction port is located on the air inlet sphere, and relief opening is located on the exhaust sphere; Described space curved surface and special-shaped border are intersected and are formed two compressive planes, and two compressive planes are not of uniform size and lay respectively at the both sides of the suction port and the relief opening line of centres.The line of centres of described suction port and relief opening departs from the piston sleeve center line and is partial to less compressive plane.
Compared to existing technology, the utlity model has following beneficial effect:
1, dual cooling air flues not only can more effectively cool off the firing chamber, and owing to be provided with exhaust outlet in the suction port both sides, the heat of being taken away in the cooling procedure can carry out preheating to the mixed gas in the gas-entered passageway to a certain extent, gasoline is fully mixed with air, thereby reduce fuel consumption, improve hot machine component working life, create favorable conditions for improving compression ratio.
2, being provided with of dual ignition plug hole realized dual ignition, can further improve the burning and the discharging of motor, thereby truly accomplishes to reduce fuel consume, reduces discharging.And the dual ignition spark-plug hole employing machine of cylinder head adds, and when not needing dual ignition, but machine adds a spark-plug hole, forms single-point fire motor, for the user, has enlarged range of choice.
3, set up stiffening rib in the cylinder head cover, not only can improve the intensity of cylinder head cover, and stiffening rib is strong to impurity absorption power, can play certain filtration to machine oil, more help the heat radiation of cylinder head cover, stiffening rib also has sound deadening simultaneously, can reduce operating noise.
4, this cylinder head adopts the special-shaped firing chamber of Pear Shaped, improve the compression ratio of motor on the one hand, Yi Xing firing chamber increases distinctive compressive plane on the other hand, can more effectively improve strength of vortex and velocity of combustion in the firing chamber, thereby motor complete machine performance is improved, fuel consume reduces, and it is more abundant to burn.The firing chamber adopts mould to guarantee that the machine of having saved adds the expense that is produced simultaneously, and the reduction machine adds cost.
