Description
Technical field
The present invention relates to a kind of internal-combustion engine, particularly a kind of internal-combustion piston engine.
Background technique
Internal-combustion engine is a kind of energy conversion device, and the chemical energy of materials such as gasoline, diesel oil, rock gas is converted into heat energy through burning in cylinder, and heat energy is converted into mechanical energy through expansion, externally acting.
Internal-combustion piston engine is converted into heat energy with chemical energy in cylinder after, heat energy expands, and drive piston motion, thereby heat energy is converted into mechanical energy, be the torque that bent axle rotates through connecting rod with Conversion of energy again, externally acting.
Connecting rod is the groundwork mechanism of disc type piston IC engine, is made up of body group, piston rod group and crankshaft-flywheel group.The body group is the skeleton of motor.The piston rod group is the to-and-fro motion of piston and the linkage unit that bent axle rotates, and the energy with reciprocating motion of the pistons in expansion stroke changes into the torque that bent axle rotates.The crankshaft-flywheel group comprises bent axle and flywheel, and bent axle is externally exported acting, and flywheel relies on inertia to drive reciprocating motion of the pistons through connecting rod behind expansion stroke, for other 3 strokes are prepared as inertia mechanism.
Mostly existing internal-combustion reciprocating-pisto internal-combustion engine is quartastroke engine, and a work cycle of quartastroke engine comprises aspirating stroke, compression stroke, expansion stroke and exhaust stroke.The piston rod group changes into the energy of reciprocating motion of the pistons the torque of bent axle and flywheel rotation in expansion stroke.At other 3 strokes, piston relies on the rotator inertia of flywheel reciprocating.
At present, internal-combustion reciprocating-pisto uses crank-connecting rod linkage mechanism transmitted power, the power loss that existence causes because of moment changes and the problem of cylinder wear:
1, in the initial moment of expansion stroke; Piston is positioned at top dead center, and piston rod and bent axle are in same vertical plane, and piston rod is 0 to the opplied moment of bent axle; The active force that this moment, the fuel blast produced is maximum; But force direction is vertical with point of action linear velocity direction, does not play to promote the effect that bent axle rotates, and power loss is bigger.
2, run to from top dead center this process of piston lower dead center when piston.When top dead center,, be not converted into bent axle torsion to the pressure on the piston owing to adopt crankshaft rod structure; But the axle of directly buckling downwards; Owing to adopt the bearing shell structure, be equivalent to increase the pressure of bent axle to bearing shell, the force of sliding friction between bent axle and the bearing shell increases; Resistance when this has just increased the bent axle operation descends the efficiency of internal combustion engine.Rotation along with bent axle; Also have the phenomenon of inclined to one side cylinder, the angle of piston rod and gravitational direction increases, and the pressure along gravitational direction on the apply piston can decompose along substantially horizontal and piston rod direction; The component that produces a substantially horizontal makes piston press to casing wall; Increase the surface friction drag between piston and casing wall, cause the efficiency of internal combustion engine to descend, this also is the main cause that causes cylinder wear to accelerate.
3, the less stable of bent axle rotation; Because it is output powers not that three strokes are arranged in four strokes of four-stroke reciprocating IC engine; This just makes that having only the time of half cycle in the many corresponding cranks of the cylinder process in every two weeks of rotation is in acting; Very inhomogeneous of power, the moment of torsion output that causes internal-combustion engine although adopt the structure of multi-cylinder to reduce this now, but still can not be eliminated fully.
Summary of the invention
The technical problem that the present invention will solve: a kind of new Structure of Internal-Combustion Engine is provided, to solve power loss, cylinder wear and the power output problem of unstable of existing internal-combustion reciprocating-pisto because of using the connecting rod transmitted power to be brought.
Technological scheme of the present invention:
A kind of disc type piston IC engine comprises cylinder, piston, piston rod, main shaft, intake valve and exhaust valve, it is characterized in that: cylinder is the circular cylindrical cylinder; Plural projection is arranged at the bottom, is provided with piston in the cylinder, and piston is an annular piston; The bottom cooperates with projection; The axle sleeve that piston connects through piston rod, axle sleeve is contained on the main shaft, and main shaft is provided with valve control machanism; Cylinder is provided with intake valve and exhaust valve.The cylinder top is provided with the cylinder top cover, and the cylinder top cover is a circular cylindrical, and the sidewall of cylinder and cylinder top cover cooperates the inside and outside twice guiding groove of formation up and down, and the fluctuating of guiding groove is identical with the fluctuating of projection.
Piston rod is the T font, and its lower end connects piston, and Bearing Installation is passed through in the twice guiding groove of cylinder side wall in horizontal two ends.
Projection has 4, and the upper surface of projection is fan-shaped plane, the helicoid of left surface for rising, and the helicoid of right surface for descending, the downside on right surface offers the firing chamber.
Exhaust valve and intake valve are located at the bottom, firing chamber.
Valve control machanism is two rings, and intake valve control road is arranged on the outer shroud, and exhaust valve control road is arranged on the interior ring.
Main shaft is installed 4 flat keys along its axial direction, and the length of each flat key offers the cross keyway greater than the axial thickness of piston in the axle sleeve, little steel ball is installed on the keyway inwall, cooperates with flat key.
The minimum altitude of lateral cylinder surface casing wall is the twice of piston axial thickness.
On the same root main shaft configurable two with casing top half, the shared valve control machanism of per two cylinders.
Beneficial effect of the present invention:
1, in the expansion stroke of the present invention, combustion gas promotes the side spiral rising of piston along projection, and its motion can be decomposed into rotatablely moving in axial straight line motion and the circumferential surface.Piston drives main shaft through piston rod and rotates together, so just gives main shaft with the energy transfer of rotation, does not have the power loss of using with the existing top dead center of connecting rod.
2, the fitting surface position helicoid of projection in piston and the cylinder can contact by maintenance face in the most of the time when motion like this, and sealing effect is relatively good.
3, wearing and tearing mainly concentrate on the edge of cylinder side wall and cylinder top cover sidewall, because both cooperate the guiding groove of formed slit as piston rod up and down, the wearing and tearing of cylinder internal are very little.
4, piston whenever rotates a circle and will accomplish twice very short at interval expansion stroke in cylinder, and the output of power and moment of torsion is stable.
5, main shaft is a d-axis, and rotation stable fine is with respect to existing bent axle also processing more easily.
6, specially designed annular spiracle control mechanism, more ingenious than existing camshaft structure, structure is simpler, also can the shared valve control machanism of per two cylinders.
When 7, adopting the multi-cylinder structure, the axial vibration between per two cylinders can be cancelled out each other, and has reduced whole vibration.
8, volume is little, and is in light weight, owing to there is not connecting rod, reduced the height of motor greatly, is convenient to reduce the center of gravity of vehicle.
