Description
Technical field
The present invention relates to engine art.
Background technique
No matter two-stroke or the opposed cylinder of four-stroke all have suitable advantage to the top piston engine.In recent years, very active about the research of this respect, for example world patent WO 2006/002982, WO2007/010186A1, WO 2007/006469 and WO 2008/149061A2 etc.These schemes or be not solve the problems that the side distribution of two stroke engine cylinder sleeve is brought, or be to adopt the slip cylinder intake and exhaust modes of distribution respectively, thus complex structure caused, problem such as distribution efficient is low.Therefore, need the high opposed cylinder of a kind of distribution efficient of invention to the top piston engine.
Summary of the invention
Patent WO 2007/006469A2 discloses a kind of slide-cylinder gas distribution structure really, but its distribution road is that intake and exhaust split, and the present invention can realize more efficiently distribution process by advancing to arrange the cooperation of shared communication type air flue and slip cylinder.And this structure can make the opening process of slip cylinder be: exhaust stroke begins to open, and keeps opening state and be over until aspirating stroke, thereby has strengthened the aperture and the distribution time of distribution, finally realizes configuration more efficiently.In order further to improve the distribution effect, can establish compressor turbine at intake duct, establish power turbine at air outlet flue, and the coaxial setting of two turbines, so just can utilize the principle of jet engine, promptly utilize compressor turbine that fresh air is pressed into the firing chamber, further satisfy the requirement of motor the air inlet flux.
The so-called radial spring seal ring that floats, be with seal ring structure body and the unsteady setting of cylinder, seal ring just can rotation like this, two surface of contact that the rotation of seal ring is equal to slip cylinder and cylinder are rotating, simultaneously can be by air-guide structure is set on seal ring, guarantee seal ring by same direction rotation, thereby compensation is because high leak tightness is guaranteed in the influence that machining error, cold and hot deformation and wearing and tearing cause.So-called opening radially the combined type buoyancy elastic sealing ring be by the unsteady elastic sealing ring of two or more openings radially suit form.When assembling, the opening of different rings answers misorientation to install, and for example, the opening of two trip rings forms 180 ° mutually, and the opening of three trip rings forms 120 ° mutually.Equally, the conical surface can be made as inner conical surface or male cone (strobilus masculinus), opening radially the combined type buoyancy elastic sealing ring also can use separately or with a plurality of openings radially the combined type buoyancy elastic sealing ring dress that axially falls use.
The trapezoidal unsteady elastic sealing ring of so-called outer breach is meant when the internal orifice of seal ring contacts with the cylinder sealing, in order to guarantee that the whole deformation of seal ring is consistent as far as possible, warpage deformation can not take place when being subjected to big explosive power or closing impact force, just uniform some small gaps of opening in the outside of seal ring.In like manner, if the outside of seal ring is when corresponding surface sealing contacts, just at inboard uniform some small gaps of opening of seal ring.For opening combined type buoyancy radial spring seal ring radially, in like manner, concentrate and deformation for fear of form big stress at opening, diverse location according to seal ring and counterpart corresponding surface surface of contact, ring in the seal ring is designed to the eccentric structure body of unequal section, or the seal ring outer shroud is designed to the eccentric structure body of unequal section, and the radially deformation everywhere of opening radial spring seal ring is reached unanimity, also promptly wait the deformation trip ring; Or to open some uniform sections be that the opening degree of depth, width all equate not isopycnic breach in the inboard and corresponding outer shroud outside of encircling in seal ring, or open that some density equate but the cross section section different breach that is notch depth.
So-called rotation gas distribution structure body is to change the position for the air inlet position and the exhaust position that make motor on the cylinder circumference, to guarantee cylinder thermal uniformity in a circumferential direction, the sealing between two cylinders of guarantee opposite disposed.
So-called angle end sealing cylinder is meant the one section cylinder section that is located between two opposed cylinders, and its both ends of the surface are angled and constitute angle end sealing cylinder.The purpose of angle end sealing cylinder setting is in order to make air inlet divide two paths to enter cylinder, directly to enter air outlet flue to prevent air inlet, increasing the scavenging effect.
So-called flow guide structure body is meant and is located in the cylinder, in order to reduce the air guide member that intake and exhaust mix in cylinder.
Opposed cylinder disclosed in this invention advances to arrange shared connection air flue gas distribution structure to the top piston, both has been useful for four stroke engine, also is used in two stroke engine, also provides new development platform for the dynamic switching engine of 2 stroke/4 stroke simultaneously.
In order to overcome the above-mentioned defective of conventional engines, the invention discloses a kind of opposed pistons sliding cylinder distribution engine.The object of the present invention is achieved like this: described opposed pistons sliding cylinder distribution engine, comprise cylinder, piston, intake duct and air outlet flue, two described cylinders directly or through the indirect opposite disposed of seal constitute opposed cylinder, a described piston is set in each described cylinder, these two described pistons are oppositely installed mutually, at least one is made as the sliding cylinder that slides by central axial direction in two described cylinders, described intake duct and described air outlet flue are made as communication type distribution road, described communication type distribution road is located at two described cylinder opposite disposed to the separating surface place of top contact or be located at the separating surface place of the two ends of described seal to top contact, described communication type distribution road contacts with the direct or indirect slipper seal of described sliding cylinder, and described sliding cylinder is subjected to the timing of engine mechanism controls.
