Description
Technical field
The present invention relates to engine more particularly to a kind of rotary polygonal piston engines of fuel-economizing.
Background technique
Rotary polygonal piston engine is also known as Wankel engine, is a kind of four-stroke engine, its main feature is that three-apexed rotor
Movement be by gear engagement do planetary rotation.Inboard wall of cylinder block is close on three vertex of three-apexed rotor, and inner chamber of cylinder block is turned
Son is divided into three working regions, and inner chamber of cylinder block carries out four working cycles with the rotation of three-apexed rotor for 8-shaped.
The current main problem of rotary polygonal piston engine first is that oil consumption is high, the main reason is that combustion-chamber shape is flat
Shape, combustion path path length are easy to put out wall at narrow slit, are unfavorable for completely burned, or even have the gaseous mixture at the narrow slit of part not burn
It is just discharged, this flat combustion chamber is influenced by structure and compression ratio, is not easy to improve in structure, and flat burning
The crossflow of room is very big, is unfavorable for the multi-faceted propagation of gaseous mixture lighted with combustion flame, flame propagation is caused to be obstructed, mix
It closes gas and can't burn completely and increase with oil consumption, be unfavorable for the normal use of rotary polygonal piston engine.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of burning diffusion velocities that gaseous mixture can be improved, and can make to mix
The burning for closing gas is complete, to reach the rotary polygonal piston engine of oil-saving effect.
The technical scheme of the invention to solve the technical problem is: a kind of rotary polygonal piston engine of fuel-economizing, packet
Cylinder body and three-apexed rotor are included, the inner cavity of 8-shaped is provided in the cylinder body, the inner cavity is arranged in the three-apexed rotor
In, and three endpoints of the three-apexed rotor are slidably matched with the bore seal, are provided with air inlet on the cylinder body
Mouthful and exhaust outlet, be fixedly installed atomizer and igniter plug on the cylinder body, the center line of the atomizer and described
The long axis of cylinder body is parallel, and the jet of the atomizer is located at the front area of inlet plenum in the cylinder body, institute
The center line for the igniter plug stated is parallel with the minor axis of the cylinder body, and the igniter plug is located at the cylinder body internal combustion
The front area of room is burnt, is provided with round air slot and bleed slot on each lateral wall of the three-apexed rotor, it is described
Bleed slot and the round air slot are tangent, and the round air slot is provided centrally with cylinder boss.
Further, the distance of long axis of the center line of the atomizer to the cylinder body is the inner cavity
The 20%~30% of minor axis length, the distance of the minor axis of the center line of the igniter plug to the cylinder body are the inner cavity
Long axis length 10%~20%.
Further, the depth of the bleed slot is inwardly gradually deepened from entrance.
Compared with prior art, it is an advantage of the invention that being led due to being provided with circle on each lateral wall of three-apexed rotor
Air drain and bleed slot, and round air slot is provided centrally with cylinder boss, so that when engine operation, it can in three-apexed rotor
Lateral surface generates air flow swirl, and since swirl center mixed airflow flowing velocity is small, igniter plug can be easily by gaseous mixture point
Combustion, while air flow swirl accelerates the multi-point diffusion of flame, shortens combustion path, improves burning diffusion velocity, Er Qieyou
It is concentrated mainly on combustor head in gaseous mixture, combustion space is big, convenient for burning, more makes mixture combustion complete, reduces
Oil consumption；In addition, the structure of the rotary polygonal piston engine is simple, the good combustion easy to accomplish to gasoline, diesel oil, aviation kerosine
It burns, so that its versatility is preferable.
Detailed description of the invention
Fig. 1 is front view of the invention；
Fig. 2 is schematic perspective view of the invention；
Fig. 3 is the structural schematic diagram of three-apexed rotor of the invention.
Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
As shown, a kind of rotary polygonal piston engine of fuel-economizing, including cylinder body 1 and three-apexed rotor 2,8 are provided in cylinder body 1
The inner cavity 11 of font, three-apexed rotor 2 are arranged in inner cavity 11, and three endpoints of three-apexed rotor 2 are matched with the sealing sliding of inner cavity 11
It closes, is provided with air inlet 3 and exhaust outlet 4 on cylinder body 1, atomizer 5 and igniter plug 6 are fixedly installed on cylinder body 1, atomizer 5
Center line is parallel with the long axis of cylinder body 1, and the jet of atomizer 5 is located in cylinder body 1 at the front area A of inlet plenum,
The center line of atomizer 5 to cylinder body 1 long axis distance L be inner cavity 11 minor axis length D1 20%~30%, igniter plug 6
Center line is parallel with the minor axis of cylinder body 1, and igniter plug 6 is located at the front area B of 1 inner combustion chamber of cylinder body, igniter plug 6
Center line to cylinder body 1 minor axis distance H be inner cavity 11 long axis length D2 10%~20%, each of three-apexed rotor 2 is outer
Round air slot 21 and bleed slot 22 are provided on side wall, bleed slot 22 and round air slot 21 are tangent, and bleed slot 22
Depth is inwardly gradually deepened from entrance, and round air slot 21 is provided centrally with cylinder boss 23.
In above-described embodiment, the working principle of the rotary polygonal piston engine are as follows: three-apexed rotor 2 rotates counterclockwise, fresh
Air is inhaled into inlet plenum from air inlet 3, while atomizer 5 ejects the fuel oil of atomization and mixed with fresh air,
The fuel oil that atomizer 5 sprays mainly is ejected into the front area A of inlet plenum, forms premix fuel-air mixture in this region, with
The rotation of three-apexed rotor 2, the fuel-air mixture air-flow of premixing constantly by three-apexed rotor 2 compress flow into its lateral wall on
It in bleed slot 22, and is flowed into round air slot 21 by bleed slot 22, vortical flow is generated around cylinder boss 23, with three
The rotation of angle rotor 2 constantly generates the mobile a string whirlpool in center, and the absolute velocity of air-flow is small near swirl center, simultaneously
Vortical flow further enhances the uniformity coefficient of the air-fuel mixture in the B of combustor head region, when on 2 lateral wall of three-apexed rotor
The center (namely air flow swirl center) of cylinder boss 23 when turning to the near center location of igniter plug 6, igniter plug 6 is opened
Initial point fire, since the mixed airflow flowing absolute velocity near swirl center is small, the spark that igniter plug 6 generates is not easy to be blown
The fiery core that goes out, can readily light gaseous mixture, and light stablizes burning, drive of the flame after lighting in air flow swirl
Under, dispersed is rotated in space three-dimensional direction, the flame of rotation quickly lights the gaseous mixture multiple spot on periphery, and lights more
Point flame surrounding, which is scattered, accelerates the burning of gaseous mixture, combustion path is shortened, before being concentrated mainly on combustion chamber due to gaseous mixture
Portion, combustion space is big, convenient for burning, more makes mixture combustion complete, so that the oil consumption of rotary polygonal piston engine is reduced,
Achieve the purpose that fuel-economizing.
