Description
Technical field
The utility model relates to the horizontally-opposed twin cylinder engine of a kind of two-stroke, concrete about the horizontally-opposed twin cylinder engine of a kind of two-stroke with dual ignition plug structure.
Background technique
The horizontally-opposed twin cylinder engine of existing two-stroke many employings hemisphere type firing chamber, flat head piston, central single spark plug combustion system.When it burns, flame is from firing chamber central authorities plug ignition, and fiery core is propagated to edge of combustion chamber from the central authorities of firing chamber, and cause its propagation length far away, pressure of explosion is uneven, and fuel combustion is insufficient, and oil consumption is high, and exhaust emissions is not up to standard.In addition, if single spark plug is damaged after long-time high temperature sintering, then motor cannot start.
Model utility content
The purpose of this utility model is to provide that a kind of structure is ingenious, sufficient combustion, pressure uniform, oil consumption than low, velocity of propagation fast, reduce user cost, reduce oil-gas ratio, pancake engine dual ignition plug structure that Security is high.
For solving the problems of the technologies described above, the utility model proposes following technological scheme: a kind of pancake engine dual ignition plug structure, include cylinder body, piston and hemispheric cylinder cap, wherein become on the ring surface of 60 ° to be provided with the first spark plug and the second spark plug with the angle of the centre of sphere of described cylinder cap at described cylinder lid surface, the first spark plug and the second spark plug are symmetrical about the center of circle of place ring surface.
As a kind of preferred version of pancake engine dual ignition plug structure described in the utility model, the centre of sphere of described cylinder cap is pointed in the direction of wherein said first spark plug and the second spark plug.
As a kind of preferred version of pancake engine dual ignition plug structure described in the utility model, wherein said
First spark plug and the second spark plug are the spark plug of model of the same race.
Compared with prior art, the utility model tool has the following advantages:
One, structure is simple, designs ingenious, and dual ignition plug structure makes its burning distance of only need walking half just can light whole firing chamber, is then carry out reignition to other half firing chamber after covering whole process.
Two, sufficient combustion, pressure uniform, 60 ° of angle designs, make to arrive center, the firing chamber heart during fiery nuclear burning identical with the distance of edge of combustion chamber bottom, pressure is also uniformly distributed.
Three, velocity of propagation is fast, and two spark plug Fire explosion burnings simultaneously, form stronger eddy current rapidly, significantly accelerate propagation of flame speed, shared by rapid burning period, crank angle is less, burns rapider.
Four, Security is high, dual ignition plug structure, prevent single spark plug non-functional thus cause cannot ato unit.

Embodiment
For setting forth the technological means that the utility model adopts and the technique effect reached further, be described in detail below in conjunction with specific embodiments and the drawings.
See Fig. 1, it is the horizontally-opposed twin cylinder engine of two-stroke at horizontally-opposed dual ignition plug structure place described in the utility model, its side includes cylinder body 1, cylinder cap 2, piston (not shown), the first spark plug 3 and the second spark plug 4, and the structure of opposite side is symmetrical identical with it.
Referring to Fig. 2 to Fig. 4, the first spark plug 3 and the structural representation of the second spark plug 4 on cylinder cap 2.Wherein cylinder cap 2 is hemispherical dome structure, and the first spark plug 3 and the second spark plug 4 are symmetricly set on cylinder cap 2, and the first spark plug 3 becomes 60 ° angles with the line of hemisphere cylinder cap 2 centre of sphere with the bottom plane of cylinder cap 2 with the second spark plug 4.First spark plug 3 and the second spark plug 4 are two the same model spark plugs arranged in hemispherical combustion chamber and hemisphere cylinder cap 2 bilateral symmetry, these two spark plugs are equal with the distance at center, firing chamber, not only flame travel shortens half, and two spark plug Fire explosion burnings simultaneously, form stronger eddy current rapidly, significantly accelerate propagation of flame speed.Shared by rapid burning period, crank angle is less, burns rapider.When 5500rpm full load mode, combustion case is best.The dual ignition that the utility model provides can promote the compression ratio of this motor, when compression ratio is increased to more than 10, and single spark-plug ignition generation pinking, but there is no pinking in simultaneous ignition cylinder.This engine compression ratio is 11.A large amount of experimental results shows, when arranging spark plug about firing chamber Central Symmetry, near top dead center, in cylinder, average tubulence energy is relatively large, and velocity of combustion is the fastest, and combustion duration is the shortest, improves engine performance.
The pancake engine dual ignition plug structure that the utility model provides has reduction fuel consume ratio, reduces user cost, reduces oil-gas ratio, reduce the advantages such as exhaust emissions.Its dual ignition is not only conducive to the raising of engine power performance, and the cyclical variations rate of motor is reduced greatly, significantly improves the performance of motor.
It should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
