Abstract

The utility model provides a low-consumption internal combustion engine with a simple harmonic reciprocating motion and a bi-directionally opposed structure. The internal combustion engine comprises an external gear, an internal gear, a crank, a connecting rod, pistons and oil cylinders, and adopts a technical scheme that the crank in the simple harmonic reciprocating motion on the basic pitch circle of the external gear of a movable circle is combined with the bi-directional connecting rod so as to be connected with the opposed pistons in the concentric opposed oil cylinders. The symmetrical double movable and fixed gear pair structures can adopt a plurality of even-number combined cylinders. On the basis of the hypocycloid theoretical equation of the internal combustion engine, the fixed and the movable circles are engaged, and the simple harmonic reciprocating motion characteristic of the point P on the basic pitch circle of the movable circle external gear is utilized, the three main moving parts, namely the crank, the bi-directional connecting rod and the opposed pistons are combined to carry out a simple harmonic and liberal linear reciprocating motion under the action of the pressure P of a revolving shaft or the pistons, and therefore, the angle of the action component force 3 is removed, the abrasion is reduced, the S/D can be greater than 1.5 to 2, the displacement efficiency of the heat engine is improved, the specific fuel consumption rate is greatly reduced, and the energy-saving and emission-reduction effects are realized.

Description

The two-way low consumption internal-combustion engine of a kind of simple harmonic quantity to-and-fro motion to interposed structure

Technical field

The utility model relates to a kind of internal-combustion engine, the two-way low consumption internal-combustion engine to interposed structure of especially a kind of simple harmonic quantity to-and-fro motion.

Background technique

Usually, the major part of its connecting rod of variable capacity reciprocating IC engine is owing to restricted by the beat motion of crankshaft journal picture circle, cause the piston action force (microcephaly) and the β angle of the force direction line generation multi resonant that transmits point (major part), complexity to change, a component angle at random appears inevitably, form piston to the side pressure Pn of cylinder wall, for coordinating the contradiction of Pn and n/s, g/kw, had to sacrifice piston than the choose reasonable of stroke S/D, finally caused power of IC engine specific fuel consumption g, h, kw to remain high hot machine displacement efficiency.

The model utility content

The purpose of this utility model provides a kind of connecting rod and is transmitting its CONCENTRIC REDUCER of working procedure all with simple harmonic quantity---the motion of linear reciprocation pattern, and these connecting rod two ends (microcephaly) respectively connect a piston, finish a low consumption internal-combustion engine toward a multiple two-way linear transfiguration work done.

As everyone knows, the hypocycloid Equation Theory proves: make the closing of polygon become certain circle C, its radius is a, moving circle E radius is b, under the condition of a/b=2 (n), and moving circle E rolls in round surely C and when fricton-tight, the movement locus of any point P is the diameter of fixed round C on the moving circle E circular arc line.According to this mathematical principle, make crank with last 1 P of moving circle E and replace traditional crankshaft journal, be equipped with corresponding connecting rod, piston, cylinder, obviously, the linear reciprocation of P point (crank) is made drivening rod, piston the linear reciprocation transfiguration campaign at no component angle in cylinder, from start with at all, the motor pattern of reform internal-combustion engine main movement part is a core of the present utility model.

Technical solution adopted in the utility model is:

The crank that moving circle external gear base pitch circle is gone up the simple harmonic quantity straight reciprocating motion is equipped with two-way connecting rod and connects opposed pistons in concentric opposed cylinder.

Symmetric double is fixed, the moving gear auxiliary structure can adopt a plurality of even number cylinder combining forms.

The utility model is a foundation with the hypocycloid theoretical equation, fixed, moving two circles are got the tooth engagement, the simple harmonic quantity straight reciprocating motion characteristic of utilizing the round P of going up of moving circle external gear base pitch to order is crank, mix under the effect of two-way connecting rod and opposed pistons Zai rotation rotating shaft or piston pressure P, crank, two-way connecting rod, three internal-combustion engine main movements of opposed pistons part are done simple harmonic quantity, straight reciprocating motion freely, elimination effect component angle β, abrasion are little, S/D can＞1.5～2, hot machine displacement efficiency improves, the specific fuel consumption rate descends significantly, realizes energy-saving and emission-reduction.

Embodiment

According to the hypocycloid math equation, with the base pitch circular diameters of moving, fixed two gears press a/b=2 given condition, make that moving circle external gear 1 is targetedly moving to be placed in and to justify surely on the eccentric journal 4 of internal gear 2 concentric Zhi rotation rotating shafts 3, as Fig. 1 after rotation rotating shaft 3 rotation, 1 P that moving circle external gear 1 base pitch circle is gone up is the straight reciprocating motion that 5 appearance of crank overlap with round surely internal gear 2 base pitch circular diameters, with crank 5 is fulcrum, moving cover one two-way connecting rod 6, two-way connecting rod 6 two ends respectively connect an

opposed piston

7,8, and opposed

pistons

7,8 places concentric opposed cylinder 9,10.Particularly point out: crank 5, two-way connecting rod 6, opposed

pistons

7,8 all are on the concentric circle straight line and with round surely internal gear 2 diameter elongation line projections with

opposed cylinder

9,10 4 and overlap.Be not difficult to find out: the thermal expansion force P of

opposed pistons

7,8 passes to two-way connecting rod 6 with rectilinear direction, two-way connecting rod 6 is passed to the circular movement merit of crank 5 Zhuan Bian into rotation rotating shaft 3 with most of power, fraction is passed to the piston of one of correspondence and is made the compression stroke merit, Transmitted chains is short, its low-loss advantage of simple harmonic quantity straight line transmission mode is self-evident, this structure possesses the genetic prerequisite of increase S/D＞1.5 especially, the Δ, the S that are W=Δ E or W=FS measure increase, meet the classical mechanics formula, reduce and be easy to get with the specific fuel consumption purpose.

This internal combustion (IC) engine link rod is being transmitted its CONCENTRIC REDUCER of working procedure all with simple harmonic quantity---the motion of linear reciprocation pattern, and these connecting rod two ends (microcephaly) respectively connect a piston, finish one toward a multiple two-way linear transfiguration work done.

In application practice, optionally can adopt fixed, a plurality of even number cylinder of the moving gear auxiliary structure combining form of symmetric double, derive out the internal-combustion engine of different capacity, model, the novel automobile internal-combustion engine of especially low oil consumption, centre of gravity.
