Bar neck 3 and small rod neck 5, wherein the diameter of small rod neck 5 is equal to length of stroke, the neck face of small rod neck 5 and trunnion center
Axis 2 overlaps, and the neck over glaze of small rod neck 5 is wider than the neck face of big connecting rod neck 3 to prolonging Shen, and its width can accommodate unitary link and live
The axial width of plug 11 cylindrical circle wheel 6 adds connecting rod thickness, and small rod neck 5 is made up of cylindrical needle bearing, eccentric circular groove 4
Width is more than the diameter of unitary link piston 11 cylindrical circle wheel 6, and the degree of depth of eccentric circular groove 4 is more than unitary link piston 11
The axial width of cylindrical circle wheel 6；There are a cylindrical circle wheel 6, cylindrical circle in the connecting rod lower end of described unitary link piston 11
The diameter of wheel 6 is less than the width of eccentric circular groove 4, and the axial width of cylindrical circle wheel 6 is less than the degree of depth of eccentric circular groove 4, cylindrical
Circle wheel 6 is made up of cylindrical needle bearing, and the connecting rod lower end midpoint of unitary link piston 11 is semi-cylindrical, radian and circle
The radian of cylindricality circle wheel 6 is equal, and the central axis of semi-cylindrical central axis wheel 6 round with cylinder is on the same line,
It is arc 7 that unitary link piston 11 prolongs Shen at the semi-cylindrical diameter of lower end to both sides, the radian phase of radian and small rod neck 5
Deng, the middle-end both sides 9 of unitary link piston 11 are parallel, and width is less than the diameter of cylinder 10, and piston is fixed in the upper end of connecting rod
Middle composition unitary link piston 11, the center vertical line of the central axis of unitary link piston 11 and bent axle 1 is not same
On straight line, and two lines are parallel；Described connecting rod base 8 is concave shape straight trough, is fixed on crankcase 12 with screw rod, and the width of groove is more than
The width on unitary link piston 11 middle-end both sides 9, it is upper and lower back and forth that formation can accommodate unitary link piston 11 middle-end both sides 9
The straight trough of linear motion.
Use such scheme: eliminate the acting dead angle of crank angle 1～15 degree, can reach and do work without dead angle, 1～15
During degree explosive force maximum, bent axle can form the maximum moment being similar to stroke, be thus greatly enhanced and exceeded at present
The efficiency of existing internal combustion engine, reduces fuel oil consumption, also can extend the service life of internal combustion engine.
Four, accompanying drawing explanation: Fig. 1 is the structural representation without dead angle internal-combustion piston engine；
Fig. 2 is Figure 1A-A line bent axle 1 and the sectional view of unitary link piston 11；
Fig. 3 is the sectional view of Figure 1B-B line connecting rod base 8.
Five, detailed description of the invention: as shown in Figure 1, Figure 2, Figure 3 shows, this utility model is mainly by bent axle 1, connecting rod base 8, cylinder
10, unitary link piston 11, crankcase 12, bearing 13 form, and the annexation between them is: in crankcase 12, little
Diameter end installs bent axle 1, the off-centre operation of bent axle 1 equipped with unitary link piston 11, larger diameter end by bearing 13 through cylinder 10
Groove 4 is coupled with unitary link piston 11, when unitary link piston 11 is in by unitary link piston 11 lower end circle wheel 6
During lower dead center, the wheel limit of unitary link piston 11 lower end circle wheel 6 overlaps with trunnion central axis 2, when bent axle 1 rotates, and one
Body formula connecting rod piston 11 lower end circle wheel 6 is up along the cambered surface of eccentric circular groove 4, to away from trunnion at trunnion central axis 2
During central axis 2 distalmost end, unitary link piston 11 is equal to the diameter of small rod neck 5 by the distance that connecting rod base 8 is up, etc.
In length of stroke, now unitary link piston 11 is at top dead centre, and this trip is compression stroke；Owing to bent axle 1 continues rotation
Turning, unitary link piston 11 lower end circle wheel 6 is from descending, when one along eccentric circular groove 4 cambered surface away from trunnion central axis 2 distalmost end
When the wheel limit of body formula connecting rod piston 11 lower end circle wheel 6 goes downwards to overlap with trunnion central axis 2, unitary link piston 11 leads to
Crossing the connecting rod base 8 descending distance diameter equal to small rod neck 5, equal to length of stroke, now unitary link piston 11 is in
At lower dead center, this trip is expansion stroke；Exhaust stroke is identical with compression stroke；Intake stroke is identical with expansion stroke.This reality
By novel structural feature be: when crank angle 1～15 degree, the force action that bent axle is done work by piston with piston middle spindle
On the crank throw that line is parallel, thereby eliminate the acting dead angle of crank angle 1～15 degree, can reach and do work without dead angle, at song
When Shaft angle 1～15 degree of explosive force maximums, can form the maximum moment being similar to stroke on bent axle, this is current existing work
Piston type internal-combustion engine is beyond one's reach, and is thus greatly enhanced and has exceeded the efficiency of current existing internal combustion engine.
