Description
Technical field
The utility model relates to field of internal combustion engine, relates more specifically to a kind of round stroke acting type internal-combustion engine.
Background technique
Nowadays Chang Yong internal-combustion engine has a variety ofly, and stroke piston combustion engine is common to be the configuration of two-stroke or four-stroke.This internal-combustion engine can comprise one or more independently pistons reciprocating in cylinder, and these cylinders are arranged with various different configurations, comprised " V ", inline or flat opposed internal-combustion engine.These pistons are coupled to arbor usually, in down stroke fuel/air mixture are sucked cylinder, and in up stroke compressed fuel/air mixture.Fuel/air mixture is lighted by spark plug or other devices near the stroke of piston top, and the burning of generation and expansion driven piston are downward, thus the chemical energy of fuel is converted into the mechanical energy of arbor.
As everyone knows, conventional stroke piston combustion engine has many restrictions, such as, a large amount of chemical energy of fuel are wasted with the form of heat and friction.As a result, 25% kinetic energy that has really changed into the arbor operation of only having an appointment of the fuel energy in general car or the motorcycle IC engine.
Summary of the invention
Problem to be solved in the utility model is: a kind of round stroke acting type internal-combustion engine is provided under the prerequisite of the number of cylinders that does not increase piston IC engine or piston diameter, and the power of IC engine that can be multiplied, and make the output of internal-combustion engine torsion more balanced.
For solving this technical problem, the utility model is achieved by the following technical solutions.
A kind of round stroke acting type internal-combustion engine is characterized in that, comprises cylinder and crankcase; Described cylinder comprises upper cylinder cover, following cylinder cap, cylinder body, is positioned at the piston at cylinder body center, the straight connecting rod of fixedly connected piston; Described crankcase comprises upper box lid, following case lid, is provided with bent axle, crank-connecting rod in the crankcase; Described straight connecting rod slip is stretched out described cylinder cap down and is slided and stretch into described crankcase, flexibly connects described crank-connecting rod; Described piston is separated upper combustion chamber and lower combustion chamber with described cylinder, and corresponding upper combustion chamber and lower combustion chamber are respectively arranged with suction tude independent of each other and outlet pipe, and described upper cylinder cover, following cylinder cap arrange the spark plug of corresponding upper combustion chamber and lower combustion chamber respectively.
The characteristics of technique scheme and further the improvement are:
The following cylinder cap of described cylinder and the upper box lid of crankcase are an overall structure.
Described middle of piston is provided with annular oil groove, and the cylinder body middle part of corresponding described cylinder is provided with oilhole.
In the round stroke acting type internal-combustion engine of the present utility model, piston is separated upper combustion chamber and lower combustion chamber with cylinder, corresponding upper combustion chamber and lower combustion chamber are respectively arranged with suction tude independent of each other and outlet pipe, and upper cylinder cover, cylinder cap arranges the spark plug of corresponding upper combustion chamber and lower combustion chamber respectively down.Like this, upper combustion chamber and lower combustion chamber have the function of alternately doing work respectively, a cylinder are done work be equivalent to the cylinder with two two stroke IC engines to do work simultaneously, and piston is no matter be upwards or to down stroke can both do work.The said structure power of IC engine that can be multiplied, and make the output of internal-combustion engine torsion more balanced, more stable.

Fig. 2 is the exploded perspective view at the another kind of visual angle of Fig. 1;
Among the figure: 1, spark plug; 2, upper cylinder cover; 3, cylinder body; 4, oilhole; 5, suction tude; 6, annular oil groove; 7, piston; 8, straight connecting rod; 9, crank-connecting rod; 10, following cylinder cap; 11, upper box lid; 12, bent axle; 13, following case lid; 14, outlet pipe; 15, compression ring; 16, oil ring.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of round stroke acting type internal-combustion engine of the present utility model is described, main cylinder and crankcase.
Wherein, cylinder comprises upper cylinder cover 2, following cylinder cap 10, cylinder body 3, is positioned at the piston 7 at cylinder body 3 centers, the straight connecting rod 8 of fixedly connected piston 7; Piston 7 is separated upper combustion chamber and lower combustion chamber with cylinder, and corresponding upper combustion chamber and lower combustion chamber are respectively arranged with suction tude 5 independent of each other and outlet pipe 14, and upper cylinder cover 2, down the spark plug 1 of corresponding upper combustion chamber and lower combustion chamber is set on the cylinder cap 10 respectively.The middle part of piston 7 is provided with annular oil groove 6, and cylinder body 3 middle parts of corresponding cylinder are provided with oilhole 4, is used for the lubricated of 3 of piston 7 and cylinder bodies.Two end part near piston 7 are provided with compression ring 15 and oil ring 16 respectively, are used for sealing.
Wherein, crankcase comprises upper box lid 13, following case lid 13, is provided with bent axle 12, crank-connecting rod 9 in the crankcase; Crankcase was stretched in cylinder cap 10 and slip under the straight connecting rod 8 of piston 7 slided and stretches out, and flexibly connected crank-connecting rod 9, and crank-connecting rod 9 flexibly connects bent axle 12.In the present embodiment, the following cylinder cap 10 of cylinder and the upper box lid 11 of crankcase are designed to an overall structure, wherein descend the cross section of cylinder cap part more preferably greater than the cross section of upper box lid part, make things convenient for that spark plug is oblique to be installed in down the cylinder cap part, and stretch in the cylinder.Such overall structure only need arrange the slipper seal that cover compression ring and an oil ring is used for piston rod.
The piston motion is done work when moving back and forth in cylinder body mutually, air-breathing and exhaust, the action complementation between acting and the punching press stroke, and an end drives the bent axle motion in acting, just in time compress the gas of the other end simultaneously.Lower combustion chamber also just in time compressed fresh combustible gas and finishes when range was done work by upper combustion chamber, and at this time incoming mixture is lighted by lower combustion chamber, and the lower end begins acting and promotes the piston stroking upward acting conversely again.Upper combustion chamber once carried out exhaust, air inlet, lights when piston moved upward.Upper combustion chamber also just in time compresses virgin gas and finishes during to top dead center Deng piston stroking upward, and at this time incoming mixture is lighted by upper combustion chamber, promotes the descent of piston acting, and circulation repeatedly.So also solved the problem of double cylinder IC engine absolute synchronization.
Round stroke acting type internal-combustion engine of the present utility model, compact structure, under the prerequisite of the number of cylinders that does not increase piston IC engine or piston diameter, the power of IC engine that can be multiplied, and make the output of internal-combustion engine torsion more balanced.
Although below by reference to the accompanying drawings embodiment of the present utility model is described, the utility model is not limited to above-mentioned specific embodiments and applications field, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art under the situation that does not break away from the scope that the utility model claim protects, can also make a variety of forms under the enlightenment of this specification, these all belong to the row of the utility model protection.
