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, by the chemical energy of the materials such as gasoline, diesel oil, rock gas, by burning conversion in cylinder, is heat energy, and heat energy is converted into mechanical energy by expansion, externally acting.
Internal-combustion piston engine is converted into chemical energy after heat energy in cylinder, and heat energy expands, and drives piston movement, thereby heat energy is converted into mechanical energy, then by Conversion of Energy, be the torque that bent axle rotates by connecting rod, externally acting.
Connecting rod is the groundwork mechanism of disc piston internal-combustion engine, body group, piston rod group and crankshaft-flywheel group, consists of.Body group is the skeleton of motor.Piston rod group is the to-and-fro motion of piston and the linkage unit that bent axle rotates, and the energy of reciprocating motion of the pistons is changed into the torque that bent axle rotates in expansion stroke.Crankshaft-flywheel group comprises bent axle and flywheel, and bent axle is externally exported acting, and flywheel, as inertial mechanism, relies on inertia to drive reciprocating motion of the pistons by connecting rod after expansion stroke, for other 3 strokes are prepared.
Existing internal-combustion reciprocating-pisto internal-combustion engine mostly is quartastroke engine, and a work cycle of quartastroke engine comprises aspirating stroke, compression stroke, expansion stroke and exhaust stroke.In expansion stroke, piston rod group changes into the energy of reciprocating motion of the pistons the torque of bent axle and flywheel rotation.At other 3 strokes, piston relies on the rotator inertia of flywheel reciprocating.
At present, internal-combustion reciprocating-pisto is used crank-connecting rod linkage mechanism transmitted power, the power loss that existence causes because moment changes and the problem of cylinder wear:
1, at expansion stroke initial time, piston is positioned at top dead center, piston rod and bent axle are in same vertical plane, piston rod is 0 to the opplied moment of bent axle, the active force that now fuel blast produces is maximum, but force direction is vertical with point of action linear velocity direction, do not play and promote the effect that bent axle rotates, power loss is larger.
2, when piston runs to from top dead center this process of piston lower dead center.When top dead center, owing to adopting crankshaft rod structure, the pressure on piston is not converted into bent axle torsion, but the axle of directly buckling downwards, owing to adopting bearing bush structure, be equivalent to increase the pressure of bent axle to bearing shell, the force of sliding friction between bent axle and bearing shell increases, resistance when this has just increased bent axle operation, declines 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, the pressure along gravitational direction on apply piston can be along substantially horizontal and piston rod Directional Decomposition, 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 decline, this is also the main cause that causes cylinder wear to accelerate.
3, the less stable that bent axle rotates, in four strokes due to four-stroke reciprocating IC engine, having three strokes is output powers not, this just makes in an every rotation of the multipair crank of answering of the cylinder process of two weeks, to only have the time of half cycle is in acting, very inhomogeneous of power, the moment of torsion output that causes internal-combustion engine, although adopt now the structure of multi-cylinder to reduce this, but still can not eliminate completely.
Summary of the invention
The technical problem to be solved in the present invention: provide a kind of new Structure of Internal-Combustion Engine, to solve power loss, cylinder wear and the power stage unsettled problem of existing internal-combustion reciprocating-pisto because using connecting rod transmitted power to be brought.
Technical solution of the present invention:
A kind of disc piston internal-combustion engine, comprise cylinder, piston, piston rod, main shaft, intake valve and exhaust valve, it is characterized in that: cylinder is circular cylindrical cylinder, plural projection is arranged at bottom, is provided with piston in cylinder, and piston is annular piston, bottom coordinates with projection, the axle sleeve that piston connects by piston rod, axle sleeve is contained on main shaft, and main shaft is provided with valve control machanism; Cylinder is provided with intake valve and exhaust valve.Cylinder top is provided with cylinder top cover, and cylinder top cover is circular cylindrical, and the sidewall of cylinder and cylinder top cover coordinates 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 T font, and its lower end connects piston, and horizontal two ends are arranged in the twice guiding groove of cylinder side wall by bearing.
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 declining, the downside on right surface offers firing chamber.
Exhaust valve and intake valve are located at bottom, firing chamber.
Valve control machanism is two rings, has intake valve to control road on outer shroud, has exhaust valve to control road on interior ring.
Main shaft is installed 4 flat keys along its axial direction, and each flat key length is greater than the axial thickness of piston, offers cross keyway in axle sleeve, and little steel ball is installed on keyway inwall, coordinates with flat key.
The minimum altitude of lateral cylinder surface casing wall is the twice of piston axial thickness.
With on main shaft one by one configurable two with casing top half, every two cylinders share a valve control machanism.
Beneficial effect of the present invention:
1, in expansion stroke of the present invention, combustion gas promotes piston along the side spiral of projection, and its motion can be decomposed into rotatablely moving in axial straight line motion and circumferential surface.Piston drives main shaft to rotate together by piston rod, so just the energy of rotation is passed to main shaft, 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 cylinder can contact by maintenance face like this when motion within the most of the time, 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 coordinate formed gap as the guiding groove of piston rod up and down, the wearing and tearing of cylinder internal are very little.
4, in a cylinder, piston often rotates a circle and will complete twice very short expansion stroke of interval, the stable output of power and moment of torsion.
5, main shaft is d-axis, and the stability of rotation is fine, with respect to existing bent axle also more easily processing.
6, specially designed annular spiracle control mechanism, more ingenious than existing camshaft structure, structure is simpler, also can share a valve control machanism by every two cylinders.
While 7, adopting multi-cylinder structure, the axial vibration between every two cylinders can be cancelled out each other, and has reduced whole vibration.
8, volume is little, lightweight, owing to there is no connecting rod, has greatly reduced the height of motor, is convenient to reduce the center of gravity of vehicle.
