Multiple air inlet interior tube bodies 32 of cloth are constituted.Air inlet interior tube body 32 has elasticity and cross section is circular arc, and air inlet interior tube body 32 relies on
The elasticity of self so that both sides of the edge can be opened towards outside all the time, therefore can begin in the both sides of the edge of air inlet interior tube body 32
Can contact with the circular arc internal face of air inlet Outer Tube 31 eventually, multiple air inlet interior tube bodies 32 or multiple air inlet interior tube body 32 with enter
The internal face of gas Outer Tube 31 surrounds to be formed and allows fresh air enter and circumferentially closed inlet channel 36, and air inlet leads to air inlet
Road 36 connects, and fresh air is in inlet channel 36 air inlet cylinder block.By regulating the position of each air inlet interior tube body 32, permissible
The aperture size of regulation inlet channel 36.When the aperture minimum of inlet channel 36, only by the circle of multiple air inlet interior tube bodies 32
Annular inner wall bread enclose formation inlet channel 36, now the both sides of the edge of each air inlet interior tube body 32 respectively with in adjacent air inlet
Body 32 keeps contact, surrounds and forms circumferentially closed inlet channel 36.When the aperture maximum of inlet channel 36, the most adjacent
Distance between two air inlet interior tube bodies 32 is farthest, the both sides of the edge of each air inlet interior tube body 32 respectively with air inlet Outer Tube 31
Internal face keeps contact, surrounds and forms circumferentially closed inlet channel 36.
As shown in Figure 4 and Figure 5, in air inlet pipe 3 also includes being arranged at air inlet Outer Tube 31 and for air inlet interior tube body 32
Applying to make the second driving means of its driving force moved radially, the second driving means includes being arranged on air inlet Outer Tube 31
The second coil 33, be arranged on air inlet interior tube body 32 and the second armature 34 of matching with the second coil 33 and be arranged at into
In gas Outer Tube 31 and for applying to make its driving force moved towards air inlet Outer Tube 31 center to air inlet interior tube body 32
Second spring 35, the second spring 35 is clipped between air inlet Outer Tube 31 and air inlet interior tube body 32.Can be right after second coil 33 energising
Second armature 34 produces captivation, after captivation overcomes the elastic force of the second spring 35, and then pulls air inlet interior tube body 32 towards far
Move from the center of air inlet Outer Tube 31, make the aperture of inlet channel 36 increase.When after the second coil 33 power-off, the second spring
The active force that 35 pairs of air inlet interior tube bodies 32 apply, makes air inlet interior tube body 32 move towards the center near air inlet Outer Tube 31,
Each air inlet interior tube body 32 is made to reset.
As shown in Figure 4 and Figure 5, in the present embodiment, air inlet interior conduit is to be made up of two air inlet interior tube bodies 32, and two are entered
Gas interior tube body 32 is for being oppositely arranged, and air inlet interior tube body 32 is semicolumn body, the both sides of the edge contact of two air inlet interior tube bodies 32
Time, the air inlet interior conduit of formation is complete cylindrical tube.Air inlet Outer Tube 31 be cross section be the body of 8-shaped, inside it
Having two radians ring-shaped inner wall face 37 more than 180 degree, the both sides of the edge of two internal faces 37 are connected, two internal faces
37 for being symmetrical arranged, and two air inlet interior tube bodies 32 are arranged to move in the region between two internal faces 37, each
The both sides of the edge of air inlet interior tube body 32 keep contact condition with an internal face 37 all the time, it is ensured that the circumference envelope of inlet channel 36
Close.
As shown in figures 1 to 6, one end of connecting rod is arranged at the big end 41 that bent axle connects, and the other end is arranged and piston
Pin 5 is threaded and constitutes the drive division 42 of worm drive, and the outer surface of drive division 42 has external screw thread, in piston pin 5
Having the screwed hole extending radially through setting at the heart, piston pin 5 is horizontally installed on piston.Bent axle rotates, at bent axle
When driving piston to pump, owing to piston pin 5 and drive division 42 constitute worm drive, so that piston pin 5 is relative
Rotating in drive division 42, piston pin 5 also drives piston to rotate while pumping.Due to work
The interconnection function of plug pin 5 drives piston to rotate, so piston is when up, and compressing inflammable mixture gas body, can while driving
Combustion mixed gas rotates so that it is mixing is more abundant, and burning will be more abundant, the more energy of release；During descent of piston, self
Not only rotating but also drive waste gas to rotate, make that waste gas discharges is more abundant, the most not only saves fuel but also reduce the discharge of pollutant.
As shown in Figure 1 and Figure 7, two stroke engine of the present utility model also includes the scavenging blade 8 being arranged on bent axle.
The air-flow major part that mouth of taking a breath in two stroke engine scavenging period goes out is the pressure differential by air-flow itself Yu displacement
And work in entering cylinder, thus the compression degree of gaseous mixture is the highest, after bent axle increases scavenging blade 8, scavenging blade 8 can
Promote that air velocity reaches to compress gaseous mixture effect to play, so before gaseous mixture enters cylinder, there is certain compression journey
Degree, more abundant when can make mixture combustion, send higher power.
Above in association with accompanying drawing, this utility model is exemplarily described.Obviously, this utility model implements not
Limited by aforesaid way.As long as have employed the various unsubstantialities that method of the present utility model design is carried out with technical scheme
Improvement；Or the most improved, above-mentioned design of the present utility model and technical scheme are directly applied to other occasion, all at this
Within the protection domain of utility model.
