Abstract
The utility model discloses a cylinder cover of a motorcycle engine, which comprises a cooling air channel arranged at the inner part of the cylinder cover. The cooling air channel comprises a cooling air inlet and a cooling air outlet. A spark plug mounting hole arranged in the cooling air channel is led to a combustion chamber. A guiding radiation sheet is arranged on the cooling air channel. The design ensures the directional flow of cold air. In addition, the guiding radiation sheet points to the cooling air outlet from the cooling air inlet, therefore heat in the cylinder cover is carried off in time effectively. The radiation efficiency of the cylinder cover is raised, and the service life and the reliability of a motorcycle engine are enhanced.
Description
Technical field
The utility model relates to a kind of motorcycle engine, particularly the forced air cooling motorcycle engine cylinder cap.
Background technique
The cooling duct zone heat load of motorcycle engine cylinder cap is very serious, is easy to generate heat fatigue cracking, is the main cause that causes cylinder head to damage.Therefore, guarantee that this zone has enough cooling spaces and intensity of cooling is one of emphasis during air cylinder head structure is arranged.In order effectively to prevent thermal fatigue, fitness for purpose should the zone maximum temperature be controlled at within the lower limit: cast-iron head is 350 ℃, and the aluminium alloy cylinder lid is 220 ℃.
Existing pedal motorcycle engine cylinder cap cooling airway zone, cool air enters to turn round behind the cooling duct turning from the cooling air import again and discharges from the cooling duct outlet, cause flow of cold air to have some setbacks, the cylinder cap heat can't in time be pulled away, thereby cause the cooling duct zone overheated, seriously exceed the temperature limit that aluminium alloy cylinder covers, greatly reduce the life-span and the reliability of motorcycle engine.So develop the research schedule that a kind of motorcycle engine cylinder cap that can reduce the cylinder cap temperature has been put on people.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of motorcycle engine cylinder cap that can reduce the cylinder cap temperature.
The technological scheme that the utility model adopted is:
A kind of motorcycle engine cylinder cap comprises the cooling duct that cylinder head inside is set, and cooling duct comprises cooling air import and cooling air outlet, has spark plug mounting hole in the cooling duct and leads to the firing chamber, and described cooling duct is provided with the guiding radiating fin;
As further improvement in the technical proposal, described guiding radiating fin points to cooling air outlet from the cooling air import.
The beneficial effects of the utility model are: the utility model cooling duct is provided with the guiding radiating fin, thereby guaranteed the directional flow of cool air, in addition, the guiding radiating fin points to cooling air outlet from the cooling air import, thereby effectively the heat in the cylinder head is in time taken away, make the cylinder head radiating efficiency improve, strengthened the life-span and the reliability of motorcycle engine.
Description of drawings
Following accompanying drawing further specifies the utility model.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cut-away view of Fig. 1;
Embodiment
With reference to Fig. 1, Fig. 2, a kind of motorcycle engine cylinder cap, comprise the cooling duct 1 that cylinder head inside is set, cooling duct 1 highly can be increased during making, thereby increase the flow that passes through of cooling duct 1 heat diffusion area and cool air, cooling duct 1 includes cooling air import 11 and cooling air outlet 12, has spark plug mounting hole 2 in the cooling duct 1 and leads to firing chamber 3, described cooling duct 1 is provided with guiding radiating fin 4, thereby has guaranteed the directional flow of cool air; In addition, described guiding radiating fin 4 points to cooling air outlet 12 from cooling air import 11, thereby effectively the heat in the cylinder head is in time taken away, and makes the cylinder head radiating efficiency improve, and has strengthened the life-span and the reliability of motorcycle engine.
