Abstract
A kind of crankshaft eccentric formula high efficience motor, it is the rod journal of crankshaft to be designed as eccentric great circle, after crank arm crankshaft band piston does compression stroke to cylinder top dead centre, the rod journal off-centre operation of crankshaft gradually rotates to high-order the height for making up crank arm decline in rotation process of the crank arm from 0 degree of angle to 45 degree of angles, piston is allowed to stop in cylinder top dead centre so that pressure in cylinder and temperature-resistant, engine ignition when crank arm goes to 45 ° of degree angles, push the crankshaft arm of force for having been changed to longer section, so that engine forces increase by 25% or so on passing to each point of crank arm in the power on 45 ° -145 ° angle rotation section pistons;So that effective conversion ratio of expansion stroke energy is increased to 80% or so, the whole engine power conversion ratio than traditional approach is enhanced about more than once.
Description
Technical field
The invention is related to engine Synergistic and energy-saving technology.
Background technique
Well-known crankshaft is widely used in the machinery that linear motion is converted to circumference, is started in reciprocating piston
It more can be rated as perfect combination in machine;The size for showing power on piston in cylinder of internal combustion engine according to available data is to expand gas by generating
The volume of body and the ratio in acting front-bank rotor housing space, its spatial volume radix minimum needs the amount of expanding gas on top dead centre
It is relatively small to obtain biggish active force, after piston setting in motion crankshaft by 0 ° -145 effectively actings only 60%, and
Other 40% acting is all transformed to connecting rod and flogs a dead horse to the frictional force of bearing shell, and transmission of crankshaft is also only at 90 ° one
Point is upper to be fully transmitted to acting on crankshaft, and more or less idle work is done in all presence of other any points, but 90 ° this
The spatial volume of point upper cylinder body increases 5 times than piston on top dead centre;In crankshaft 0 --- the movement of piston in 145 ° of rotation
It will cause being gradually increased for cylinder space, that is, the space of idle work that a large amount of expanding gas is done can be transformed into bearing shell pair
The frictional force of crankshaft;And piston needs to move to and becomes piston linear movement certainly back to the circumference of 575 ° of upper crankshaft after bottom dead center
The useful work that body consumes, at this moment the dynamic function of institute on crankshaft loses more than 60% in the transfer again, damage when it is than acting
It is more to lose 40%, it is seen that transmission of crankshaft carry out power exchange in itself loss caused by energy loss can achieve 80% with
On, the energy conversion of actual forces is 20% or so, and the power root of reciprocating internal combustion engine waste is just in the transmitting and conversion of power;From
Newer two are announced at present to invent --- piston persists, this defect can be solved perfectly in late ignition high efficience motor, it
Use hydraulic top stretch pushed up automatically with cam the mode of stretching make connecting rod in 0 degree to 45 degree angle rotation process it is progressively longer with offset
The falling head (for 25% or so of length of connecting rod) of crank arm allows piston to stop the pressure so that in cylinder in cylinder top dead centre
With temperature-resistant, engine ignition when crank arm goes to 45 ° of degree angles, can so gas burning generate crunch act on
On piston, promotion has been changed to the longer section crankshaft arm of force, so that engine forces are on 45 ° -145 ° angle rotation section pistons
Power each point on increase by 25% or so, that is to say, that so that the power on piston has lost 25% or so in compression stroke less;
Therefore it is persisted using this piston, late ignition technology, greatly reduces impact to crankshaft and to side caused by cylinder wall
To the energy loss of frictional force, overcomes the power in reciprocating-piston engine and lose big defect, but the design of this two clock
Structure is more complicated, and it is higher that technique makes upper difficulty.
Summary of the invention
Efficiently start in order to which loss the invention patent of power when reducing engine power transmitting provides a kind of crankshaft eccentric formula
Machine, it is the rod journal of crankshaft to be designed as eccentric great circle, and the major part of certain connecting rod also designs larger matching, original
Reason is that eccentric ratio axle journal is being that eccentric ratio axle journal itself also corresponds to big end in the rotary course of center around trunnion
Rotation, in crank arm from 0 degree of angle to turn of 45 degree of angles after crank arm does compression stroke to cylinder top dead centre with piston
The rod journal off-centre operation of crankshaft gradually rotates to high-order the height for making up crank arm decline (for length of connecting rod during dynamic
25% or so) piston is allowed to be stopped in cylinder top dead centre so that pressure in cylinder and temperature-resistant, goes to 45 ° of degree to crank arm and press from both sides
Engine ignition when angle, at this moment can so gas burning generate crunch act on piston, promotion have been changed to it is longer
The crankshaft arm of force in section, so that power of the engine forces on 45 ° -145 ° angles rotation section pistons is to pass to crank arm each
Increase by 25% or so on a point, that is to say, that so that the power on piston has lost 25% or so in compression stroke less;This bias is even
The design of bar axle journal without the basic structure of change engine can also achieve the purpose that piston make to persist, late ignition so that doing
Effective conversion ratio of function stroke energy is increased to 80% or so, and engine integral energy conversion ratio is promoted to 40% or so, than tradition
The engine power conversion ratio of mode is enhanced about more than once.
Its beneficial effect is to greatly improve engine power.
Detailed description of the invention: Fig. 1 is the invention schematic diagram;Fig. 2 is that crankshaft is biased to rod journal structure chart.
In figure: 1 cylinder;2 pistons;3 smalls end of connecting rod;4 piston pins;5 big ends;6 crank arms;7 eccentric ratio axle journals;8
Trunnion.
Specific embodiment:
Piston 2 is inserted in from 1 lower end of cylinder, connecting rod small end of connecting rod 3 is connected with piston pin 4, big end 5 is the same as on crank arm 6
Eccentric ratio axle journal 7 be connected, trunnion 8 is then put in cylinder block in the support of trunnion.
