Background technique
From the structure of motor, conventional engines is because the structure of crank-connecting rod is limit, and motor piston when blast stroke and compression stroke all has very big lateral forces to cylinder inner wall.Because the distortion and the wearing and tearing of cylinder have been quickened in the existence of lateral force, wearing and tearing have just directly influenced the sealing of cylinder for a long time, and sealing is poor more, and the performance of motor, efficient and life-span will reduce greatly.In addition, for multicylinder engine, the design of the many more bent axles of cylinder number and difficulty of processing are also just big more, have also increased the quantity of connecting rod and rotatable parts simultaneously, and the problem of thereupon bringing is exactly the frictional loss rising in the motor.If can eliminate or reduce lateral force in the engine cylinder, reduce frictional loss, efficient and the life-span that will improve motor greatly.
Combustion condition from motor, the stroke of traditional motor is subjected to the influence of cylinder diameter bigger, when Piston Compression arrives top dead center, the top of piston is very little apart from the distance of cylinder head bottom, so just directly cause piston when being in top dead center, there is slit in the firing chamber, influences the oil gas mixability in the cylinder.Owing to can't be mixed at edge of combustion chamber slit place fuel oil, the temperature in the explosion time cylinder raises rapidly, and the place just is easy to produce nitrogen oxide at the edge slit, thereby has influenced the environmental-protecting performance of motor.Also just be readily solved if can design this type of problem of motor of a kind of big stroke, the combustion efficiency of motor and discharging all can make moderate progress.
Need to design no lateral force in a kind of cylinder for this reason, can realize big stroke, frictional loss is little, new work engine simple in structure.
Summary of the invention
Purpose of the present invention will realize that exactly engine piston does not have lateral forces to cylinder, can realize big stroke, and frictional loss is little, new work engine simple in structure.The invention discloses a kind of engine with external connecting rod for this reason, comprising: cylinder, piston, link is slidingly connected part, and the specific implementation form is as follows:
Described piston connects with described link, and described link connects with described sliding motion structure spare, and described sliding motion structure spare rotates with external connecting rod and connects, and described external connecting rod rotates with external bent axle and connects, and described external bent axle is made as overhead type or side-mounted.
Be symmetrical arranged two described external connecting rods in a motor, described external bent axle is made as overhead type.
The described external bent axle that two sides are provided with is set in a motor, and two described external bent axles are made as through gear A and gear B and are meshed, and described sliding motion structure spare connects with described external bent axle through slide block.
In multicylinder engine, described piston is made as opposed type and constitutes cylinder in-block, described external connecting rod is located at the both sides of single described cylinder in-block or a plurality of described cylinder in-blocks, or in the multicylinder engine of being made up of described cylinder in-block, described external connecting rod is located between the described cylinder in-block.
The arrangement mode of described cylinder is made as the linear array formula, rectangular arranged formula or circular arrangement formula.
Two or more described cylinders are set up in parallel, described external bent axle is through the gear connection that is meshing with each other, or the shared described external bent axle of the described cylinder that is set up in parallel, the work phase place of described piston in the described cylinder that is set up in parallel on described external bent axle can be made as identical or different, and the axis of the described cylinder that is set up in parallel can be made as parallel type or non-flat line.
Be provided with cylinder apart from adjusting mechanism between two described cylinders of opposite disposed, described cylinder is made as mechanical type or hydraulic type apart from adjusting mechanism.
