Abstract
The invention relates to a connecting rod offset type engine, comprising a connecting rod and a crankshaft, which is characterized in that the shaft hole on the upper segment of the connecting rod is connected with the piston through a piston pin; the shaft hole on the lower segment of the connecting rod is connected with the crank pin; the center lines of the two shaft hole rods of the connecting rod are mutually offset arranged; when the piston is positioned on the top dead center, the center line on the upper segment of the connecting rod and the center line of the cylinder and the center line of the crank pin can form an included angle, and the force action point and the action direction can be deviated through the lower segment action of the connecting rod, thus, when the crankshaft is positioned on the top dead center, a force arm more than zero is provided in advance. The connecting rod offset type engine has the advantages that a force arm more than zero is provided in advance on the crankshaft when the piston is positioned on the top dead center due to the adoption of the offset design for the connecting rod, and the force arm can be increased rapidly and in advance when positioning in the certain of crankshaft corner behind the top dead center, meanwhile the maximum combustion pressure can be transferred to the force arm of the crankshaft and become useful work when the piston is positioned on the top dead center, the purpose of enhancing the energy conversion rate of the engine and reducing the mechanical loading can be reached.
Description
[technical field]
The present invention relates to a kind of motor, relate in particular to a kind of connecting-rod offset engine.
[background technique]
In existing Reciprocating engine, its connecting rod center line of diaxon vent stem up and down all is on the same straight line, and its cylinder centerline also all is vertically to pass through bent axle (rotating shaft) center.This type of pattern design of crankshaft ﹠ connecting, when making piston be in top dead center, line of action of force has passed through rotating shaft, the bent axle arm of force that causes this moment is zero, increasing along with descent of piston and crank angle, the speedup increment of its bent axle arm of force also is very slowly, when firing pressure is the highest just during piston top dead center, in certain crank angle of atdc, firing pressure still is in very high or higher state, and the bent axle of this moment does not have the arm of force or its arm of force is very little, finally causes a large amount of firing pressures to be converted into heavy mechanical load and becomes idle work and slattern.
[summary of the invention]
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of energy conversion rate height, mechanical load connecting-rod offset engine low and simple in structure.
The technical solution adopted for the present invention to solve the technical problems is: a kind of connecting-rod offset engine, comprise piston, connecting rod, bent axle and cylinder body, and the axis hole that is positioned at the connecting rod epimere is connected with piston by wrist pin, and the axis hole of connecting rod hypomere is connected with crank pin; The described connecting rod center line of diaxon vent stem up and down is offset setting mutually, when piston is positioned at top dead center, connecting rod epimere center line and cylinder centerline and crank pin centreline space have respectively formed an angle, and the effect by the connecting rod hypomere, the point of action and the action direction of exerting all one's strength are offset, and make bent axle just have one in advance greater than the zero arm of force when top dead center.
Described connecting rod divides upper and lower two sections or upper, middle and lower more than three sections or three sections, and it is shaped as " 7 " font or " Z " font or curvilinerar figure.
Each segment length of described connecting rod equates or is unequal that described each section of connecting rod center line is not on same straight line.
Described motor can adopt the connecting-rod offset design separately, can also adopt the design of crankshaft ﹠ connecting double offset formula.
The invention has the beneficial effects as follows: take the connecting-rod offset design, bent axle when making piston be in top dead center has had one in advance greater than the zero arm of force, and the arm of force that makes bent axle on this basis, can obtain in certain crank angle After Top Center increasing in advance and rapidly, maximum combustion pressure when this moment, piston was in top dead center no longer all acts on the crankshaft center, but part or most transferring on the arm of force that this moment, bent axle had in advance, become useful work and utilized, firing pressure in certain crank angle of atdc is still very high, also be fully utilized under the effect of the bent axle arm of force that After Top Center increases rapidly, reach the purpose that improves the engine power conversion ratio and reduce mechanical load.

[embodiment]
The present invention is further described below in conjunction with drawings and Examples.
Referring to Fig. 1, a kind of connecting-rod offset engine, comprise piston 2, connecting rod 3, bent axle 5 and cylinder body 1, described connecting rod about in the of 3 two axis holes, 4 bar center lines be offset setting mutually, referring to Fig. 3, Fig. 4 and Fig. 5, described connecting rod 3 is divided into two sections or upper, middle and lower more than three sections, approximate 7 fonts of its shape or zigzag or curvilinerar figure, described connecting rod 3 each segment length equate or are unequal that described connecting rod 3 each section center lines are not on same straight line; The axis hole 4 of described connecting rod epimere is connected with piston 2 by wrist pin, the axis hole 4 of connecting rod hypomere is connected with crank 7 pins, after described connection is finished, when piston top dead center, connecting rod epimere center line and cylinder 6 center lines and crank 7 center lines have respectively formed an angle, and the effect by the connecting rod hypomere, the point of action of connecting rod 3 power is offset, make between connecting rod 3 lines of action of force and rotating shaft (bent axle 5) and produced one section vertical distance, had one when causing bent axle 5 top dead centers in advance greater than the zero arm of force, and the arm of force that makes bent axle 5 on this basis, can obtain in certain corner After Top Center increasing in advance and rapidly and produce beneficial effect.
Described motor can adopt the connecting-rod offset design separately, referring to Fig. 2, can also adopt the design of crankshaft ﹠ connecting double offset formula.Except its crankshaft ﹠ connecting has been done the aforesaid improvement, work system that other are all and operation mechanism and existing Reciprocating engine are identical when practical application in the present invention, its working principle and use the mode of operation also just the same.
