The advantage is: the cooling effect is good, and power is higher relatively, and life is longer moreover.
Description
Technical field
The utility model relates to the technical field of motor, especially relates to a kind of cooling-down type cylinder head.
Background technique
Current engine for motorcycle cylinder head on the market, it is all the effect reaching cooling by forced air cooling, the rising of control temperature, because of the restriction of its internal structure, add the defect of some designs itself, there will be the outstanding problem that the coolings such as traditional cylinder head firing chamber are inadequate, valve ridge area cooling effect is difficult to, simultaneously the design deficiency of intake and exhaust port, causes installation question also very difficult, thus causes overheated, the bad phenomenon such as power is low, the life-span is short of motor.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of good cooling results, and power is relatively high, and the cooling-down type cylinder head that working life is longer.
For realizing above-mentioned object, the utility model provides following technological scheme:
A kind of cooling-down type cylinder head, the body of cylinder head is the cavity with one end open, body is provided with the air-cooled passage communicated with cavity, both sides relative at the bottom of cavity chamber are respectively equipped with one group of erection column, often organize erection column to be made up of two erection columns, all connected by connecting plate between two erection columns often organized, the middle part of connecting plate is to the recessed formation groove of bottom direction, mounting hole is provided with between two adjacent erection columns of two groups, two mounting holes are installed into valve and exhaust nozzle respectively, the outer side wall of body is provided with some circle radiating fin, the radiating fin of the same side is reduced respectively to the top of body and bottom by middle part gradually relative to the height of corresponding sidewall, the height of body is 73mm.
The utility model is set to further: the angle between described inlet and outlet mouth is 48 ° ~ 50 °.
The utility model is set to further: the angle between described inlet and outlet mouth is 49 °.
The utility model is set to further: the thickness of described radiating fin is 2.5mm.
By adopting technique scheme, the technique effect that the utility model reaches is:
1, this cylinder head to increase on Primordial Qi cylinder head basis on 13mm, and adopt heat radiating fin structure to design, effectively breach the outstanding problem that the coolings such as traditional cylinder head firing chamber are inadequate, the valve ridge area cooling of the most difficult cooling is particularly made obviously to improve, through verification experimental verification, adopt this structure rear cylinder head temperature to reduce degree of convergence and reach more than 10%;
2, this cylinder head has also spherically made the structure of firing chamber into spherical combustion chamber by original and irregular, shorten delay period, burning is more abundant, improves the design of intake and exhaust port simultaneously, make air inlet more abundant, exhaust is more thorough, effectively improves power performance, through verification experimental verification, power improves 11%, bring up to 6.0kW by the 5.4kW originally demarcated, Maximum Torque improves 10%, brings up to 8.25N.m by original 7.5N.m;
3, this engine cylinder head additionally uses secondary air compensating measure after machine, makes motor again can reach Europe Π emission request on the basis keeping power character that motor is good, power character and Economy obvious;
4, the setting angle of inlet and exhaust valve is also decreased 7 degree and 8 degree by this engine cylinder head, and the length of rocking arm is shortened, thus effectively reduces the reciprocal inertia force of rocking arm, and durability increases, and noise reduces.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is plan structure schematic diagram of the present utility model.
Fig. 2 is side-looking structural representation of the present utility model.
Fig. 3 is sectional structure schematic diagram of the present utility model.
Embodiment
With reference to Fig. 1 ~ 3, a kind of cooling-down type cylinder head disclosed in the utility model, the body 10 of cylinder head is for having the cavity of one end open, and the height of body 10 is 73mm, 13mm on Primordial Qi cylinder head basis is increased.Body 10 is provided with the air-cooled passage 11 communicated with cavity, both sides relative at the bottom of cavity chamber are respectively equipped with one group of erection column, often organize erection column to be made up of two erection columns 12, all connected by connecting plate 13 between two erection columns 12 often organized, the middle part of connecting plate 13 is to the recessed formation groove 14 of bottom direction, mounting hole 15 is provided with between two adjacent erection columns 12 of two groups, two mounting holes 15 are installed into respectively valve 16 and exhaust nozzle 17, enter, angle between exhaust nozzle is 48 ° ~ 50 °, preferably enter, angle between exhaust nozzle is 49 °, the setting angle of inlet and exhaust valve is decreased 7 degree and 8 degree, the length of rocking arm is shortened, thus effectively reduce the reciprocal inertia force of rocking arm, durability increases, noise reduces.The outer side wall of body 10 is provided with some circle radiating fin 18, and the radiating fin 18 of the same side is reduced respectively to the top of body and bottom by middle part gradually relative to the height of corresponding sidewall, and the thickness of radiating fin 18 is 2.5mm.Employing heat radiating fin structure designs, and effectively breaches the outstanding problem that the coolings such as traditional cylinder head firing chamber are inadequate, particularly makes the valve ridge area cooling of the most difficult cooling obviously improve.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
