Description
The present invention relates to a kind of new structure of reciprocating IC engine power output in upright arrangement.
Which kind of fuel existing reciprocating IC engine no matter use, no matter two-stroke or four-stroke, all be to do straight reciprocating motion by piston in cylinder, piston links together by connecting rod and crank, acts on the crank of bent axle, pull crankshaft rotating, by the crankshaft end outputting power.Bent axle also has control piston by regular movement with keep effect such as circulation grade except outputting power.
In power stroke, theoretically, work done be from piston on last summit, the crank center line begins when overlapping with the cylinder barrel center.We claim that at this moment degree in crank angle is 0 degree, and gas expands and promotes the piston work done.Pull crankshaft rotating by connecting rod, crank, with moment of torsion form outputting power, work done is to forward 180 degree to since 0 degree to finish.Moment of torsion=active force * work done arm of force length.Crank is within the angle of work done, and its work done arm of force length equals the value that crank radius multiply by sin, that is: sin0 ° to sin180 °.We know that the sin value is progressively to rise in value to 1 by 0 at 0 degree, progressively narrows down to 0 from 1 again to 180 degree.Piston is in power stroke so, acts on work done arm of force length on the bent axle and be from 0 to rise to crank radius, narrows down to 0 from crank radius again; Under the certain situation of active force, contrast work done arm of force length within 180 degree of work done is crank radius or bigger all the time, has lost a lot of merits.According to simple rope, with this structure of crankshaft end outputting power, there is not exception the home and abroad up to reciprocating IC engine.
The objective of the invention is, on the basis of original reciprocating IC engine in upright arrangement, adopt this structure outputting power, making its work done arm of force length is maximum value all the time, improves the output power of reciprocating IC engine.
The object of the present invention is achieved like this, on original reciprocating IC engine in upright arrangement, with the corresponding one side of camshaft establish a special outputting power that clutch gear is housed, pto; Between piston and connecting rod, establish the engagement of a tooth bar and clutch gear.In power stroke, clutch gear and pto are bonding state, and piston promotes tooth bar, and clutch gear pulled by tooth bar and pto rotates.Thereby guaranteed that workmanship's arm of force length is maximum value all the time.During piston stroking upward, the separated attitude of clutch gear and pto has guaranteed that pto continues rotation by former direction.Original bent axle is being undertaken all functions except that power output.
Theory according to the actual work done arm of force of the original crank radius length that converts:
Original work power arm lengths=(π * (throw)
2)/(2 * length of piston travel)
If the clutch gear radius length of this power output structure equates with throw, new work power arm lengths=throw then.Original bent axle and this pto all are the moment of torsion works done.Because work done arm of force length has changed, the moment of torsion of its generation just changes thereupon.The moment of torsion difference that under the situation of equivalent effect power, produces.Other structure does not change, and the ratio of moment of torsion is exactly the ratio of output power.That is:
(new moment of torsion)/(former moment of torsion) * %=(active force * new work power arm lengths)/(active force * original work power arm lengths) * %
Active force is equal, then
Existing internal-combustion engine, length of piston travel=2 * throw, the substitution following formula, then:
(2 * 2 * (throw))/(π * throw) * %=(2 * 2)/(π) * %=127.4%
According to above calculating, equal internal-combustion engine as long as change its power output structure, under the situation of equal oil consumption, causes less and can improve power 27.4%.Improving power in actual motion will be above this numeral.Its reason has three: 1, because the pressure that power stroke produces when beginning is 30 kilograms/cm
2To 50 kilograms/cm
2, at this moment original work done arm of force length increases gradually from 0, and no matter active force is much, and the merit that is produced can only be to increase gradually from 0.Along with descent of piston pressure is reduced to 3 kilograms/cm gradually
2To 5 kilograms/cm
2This structure all is maximum work done arm of force length when its pressure is maximum and in the whole process.In addition, the clutch gear radius of this structure also can strengthen according to its spatial structure.2, this structure is as on the internal-combustion engine that is contained in the automobile coupling, and when the back axle rotating speed surpassed internal-combustion engine rotational speed, because the effect of clutch gear, back axle separated voluntarily with its internal-combustion engine.Vehicle is changed over to by traction automatically and slides.When 3, former internal combustion (IC) engine link rod is to the crank work done, have only connecting rod center line and the work done of crank tangent line intersection, this structure rack axis overlaps with the clutch gear tangent line all the time, the connecting rod center line and the loss of crank tangent line angle of former internal-combustion engine have been eliminated, thereby can further improve output power, enlarge its Economy.
Having improved output power is exactly the utilization ratio that has improved fuel, is exactly energy saving.
