Description
Technical field
The present invention relates to engine art.
Background technique
How precisely efficient for engines distribution is to improve engine efficiency and improve one of topmost technological means of the motor feature of environmental protection, therefore, research in this respect also is very active.The distribution seat mouth of conventional engines and distribution valve body are opened in being, such structure truly has benefit for improving distribution seat mouth (valve seat mouth just) with sealing between the valve body (valve just), opens valve body structure in still to make air current flow, airflow area and the design of distribution opening hours all be subjected to serious restriction.Therefore, in order fundamentally to solve the distribution problem of motor, need a kind of new distribution mode of invention.
Summary of the invention
The invention discloses a kind of a kind of valve body external-open air distribution structure that is located at (on the cylinder cap or on the cylinder wall) on the chamber wall.On the basis of this structure, the invention discloses a kind of distribution engine with externally opened valve body, valve body on this motor does not have the danger of valve body and piston collisions, so the stroke opening time of valve body and the design of shut-in time all have suitable flexibility, can reduce the distribution restriction loss like this, the interior air current flow of cylinder and the degree of combustion gas mixing are improved, thereby improve the efficient of motor.Utilize this structure, cover when intake valve and exhaust valve are set, open valve in the comparable tradition of aperture diameter and obviously strengthen at engine cylinder.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, or in intake duct, establish air inlet boosting device, further satisfy the requirement of motor the air inlet flux.Owing to need high leak tightness between external-open air distribution seat mouth and the valve body, so the invention discloses a kind of unsteady ring type elasticity external-open air distribution seat mouth and a kind of by the plurality of openings floating ring opening floating ring combined elastic external-open air distribution seat mouth that constitutes of mismatch suit radially.What float ring type elasticity external-open air distribution seat mouth is to utilize end face to be made as conical surface annular elastic structure at all, when being subjected to the compressing of external-open air distribution valve body, will certain displacement radially take place, thereby compensation is because machining error, the influence of axial deviation that cold and hot deformation and wearing and tearing caused are guaranteed high-seal.This conical surface annular elastic structure can be made as taper by an end face, also can all be made as taper in two ends, can be made as internal cone type or outer bevel-type as required, also can use separately or a plurality of dress use that axially falls; So-called opening floating ring combined type elasticity external-open air distribution seat mouth be by the cyclic spring structure of two or more openings radially suit form, when assembling, the opening of different rings answers misorientation to install, 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), also can use separately or with a plurality of open annular elastic structures axially heap connect use.Owing to be subjected to the effect of cylinder inner high voltage, the external-open air distribution valve body is subjected to sizable thrust, so the driving mechanism of external-open air distribution valve body should have suitable pressure to offset the pressure of cylinder to external-open distributing valve body to external-open distributing valve body, guarantee sealing, thereby the external-open air distribution valve body can be by directly drivings such as cams, also can reduce requirement like this through two linkage mechanisms again through mechanism controls such as cams to driving mechanism pressure.
Distribution engine with externally opened valve body disclosed by the invention can be used for two stroke engine or four stroke engine equally, if in intake duct, establish air inlet boosting device by adjusting the control law of air inlet external-open air distribution valve body and exhaust external-open air distribution valve body, also can be used in the boundary distribution engine.So-called boundary distribution engine is exactly that engine charge seat mouth and exhaust seat mouth have the quite long common opening time, the motor that comes the interface between the mobile inlet and outlet to carry out distribution by the air inlet boosting device that is located in the intake duct.Because externally opened valve body makes air inlet can effectively form the intake and exhaust separating surface, thereby reduces the mixing of intake and exhaust in cylinder, play the effect of efficient scavenging, efficient distribution.In order further to improve the efficient of efficient scavenging, efficient distribution, can in cylinder, establish the flow guide structure body in the suction port place, the purpose that flow guide structure is set be make as much as possible air inlet before diffusion more the degree of depth flow to cylinder bottom, near or reach near the piston head that is in the lower dead center, scavenging, distribution efficient are further improved.If motor disclosed by the invention as two stroke engine, only needs rotating speed with camshaft be made as with bent axle and equate, and the device of driving oil sprayer oil feeding mechanism is also done corresponding adjustment.This kind two stroke engine, not only can give full play to the advantage of traditional two stroke engine, the inferior position (as gas phase channelling problem etc.) of evading traditional two stroke engine, the advantage that can also make full use of modern four stroke engine (for example, VVT-i technology, changeable compression ratio technique etc.), therefore, have that volume is little, in light weight, efficient is high, the advantage such as few that discharges pollutants, distribution engine with externally opened valve body disclosed by the invention also provides new platform for making two/four-stroke dynamic translation motor.
