The further cylindrical cam axis is fixed on the circle that on cylinder body and axis passes through circumference where cylinder by bearing
The heart, cylindrical cam axis outer surface are equipped with cam profile, and the cam profile is connected with roller, the roller quantity and number of cylinders
It is identical.
A kind of cylinder cam-type crankless internal-combustion engines design method, wherein：Annular is uniformly distributed several gas on cylinder body
Cylinder when internal combustion engine, carves that always there are one cylinder operations in expansion stroke, the corner of cylindrical cam axis is in any a period of time
360 °, cylindrical cam axis outer surface cam profile realizes independent design and configuration, a work period to the stroke of every one-stroke
Interior, four different strokes design different strokes：
1）For induction stroke, the profile height by increasing air inlet section in cam profile carries out increasing suction stroke Ha, then auxiliary
Preadmission angle and retard angle is arranged, the increase of cylinder intake air quantity is realized；
2）For compression stroke, the profile height by reducing compression section in cam profile is shortened compression travel Hb, is controlled
Compression ratio and avoid phenomenon of detonation；

At primary acting.
Further roller operates in the air inlet section of cam profile first, and the inlet valve in valve actuating mechanism is opened at this time, row
Valve-closing, cylindrical cam axis are moved out by roller belts piston；After suction stroke Ha, roller enters cam profile
Compression section, the gas mixture in cylinder is inwardly compressed by roller belts piston cylindrical cam axis；Roller enters convex later
The acting section of contour line, cylinder fuel are ignited, and piston is pushed outwards dynamic, and passes through push rod and roller and drives cylindrical cam axis
Rotation, movement and power are exported by cylindrical cam axis, and inlet valve and exhaust valve are turned off in both of the aforesaid stroke；Cam profile is most
Latter section is exhaust section, is inwardly compressed by roller belts piston, at this time IC Intake Valve Closes, and exhaust valve is opened, and will be given up in cylinder
Gas excludes, and so far, cylindrical cam axis completely operates 360 °, each cylinder is also completed four with the help of flywheel inertia
A stroke, later continuously running with cylindrical cam axis, roller enter in the air inlet section of cam profile again, start next
A work period.
Compared with conventional crankshafts connecting rod type internal-combustion engine, the beneficial technical effect of the present invention lies in：
1）In one work period, different strokes can be designed for aforementioned four different strokes, engine is improved with this
Energy.For induction stroke, crankshaft connecting rod type internal combustion engine by the way that preadmission angle and retard angle is arranged, with this increase in cylinder barrel into
The increase of air inflow can be realized in tolerance by the air inlet section height increase stroke increased in cam profile in of the invention.For
Compression stroke can be controlled by suitably shortening the trip stroke and compression ratio and avoid phenomenon of detonation.It is appropriate to increase expansion stroke
Stroke, the power performance of internal combustion engine can be promoted.And for exhaust stroke, longer stroke is can configure, to be conducive in cylinder barrel
Exhaust gas is discharged more thorough.In the present invention for the configuration of the stroke of four strokes according to from big to small be ranked sequentially for：Row
Gas stroke Hd, working stroke Hc, suction stroke Ha and compression travel Hb.
2）In one work period, the corner of cylindrical cam axis be not 720 ° but 360 °, equally complete four strokes
In the case of, higher cylindrical cam axis output rotating speed can be obtained, and smooth running continuity is more preferably.
3）Cylindrical cam axis is mainly by the axial force and torque of the set roller end generation of piston push rod portion, axial force in the present invention
The generation of cylindrical cam axis can be made to topple, but equally distributed four cylinders of annular, always there are one cylinder operations at quarter in any a period of time
In expansion stroke, the roller end that piston push rod portion covers is set to apply the axial force of opposite direction to cylindrical cam axis, so as to improve circle
The axially loaded situation of column camshaft, along with cylindrical cam axial length diameter is smaller, and the continuous rigidity of circumferential material is larger, therefore this
Cylindrical cam axis oscillation crosswise reduces vibration severity, this hair much smaller than the lateral vibration earthquake intensity of bent axle in traditional combustion engine in invention
The vibration mode of bright middle cylindrical cam axis is mainly shown as torsional oscillation, by the characteristics of motion that piston push rod portion covers be designed as five times it is multinomial
Formula or cycloidal motion, you can so that cylindrical cam axis is suitable for high-speed rotating occasion, and piston push rod portion set can be improved
Compliance is moved, soft impulse and rigid shock that roller generates cylindrical cam axis can be also eliminated, so as to improve cylindrical cam
The torsional vibration characteristic of axis.
