Abstract

The utility model relates to a deformed piston which belongs to the technical field of the improvement of a piston for an internal-combustion engine. The deformed piston is mainly suitable for a four travel gasoline engine. The deformed piston is deformed mainly by rotating a piston valve in definite time to acquire an optimal shape in work. Therefore, the internal-combustion engine can exhaust thoroughly and have much fed steam, high velocity of combustion, complete combustion and very little carbon monoxide in exhaust gas. The utility model has the advantages of high efficiency, energy saving and low pollution of exhaust gas.

Description

Deformed piston

The utility model relates to a kind of deformable internal combustion engine, is mainly used in the four-journey petrol engine.

The shortcoming of present traditional combustion engine, can not thoroughly discharge cylinder to waste gas, although done a lot of measures aspect equating in exhaust valve and distribution, as increase time of outlet valve--area value, but owing to the existence of firing chamber, account for the residual gas that enters cylinder incoming mixture 5-15% and can not be discharged from eventually all the time.Thereby, the completeness and the volumetric efficiency of reduction incoming mixture velocity of combustion, burning.Finally cause incomplete combustion, off-energy and produce a large amount of toxic gas carbon monoxide, also influence the power performance of internal-combustion engine simultaneously.

The purpose of this utility model provide a kind of can be remaining in the Deformed pistons that the burning chamber waste gas is all discharged behind the combustion in IC engine.

The solution that the purpose of this utility model adopts is: the shape adapted hemispherical combustion chamber of firing chamber, spark plug places the top of hemispherical combustion chamber, both sides split an exhaust valve and an intake valve, be provided with the air outlet flue by force of a flute profile between exhaust valve and the spark plug, piston crown is provided with the hemisphere cavity that sinks into internal piston under, there are two semicircle shape projectioies at edge along piston crown, these two projectioies are that the center of circle of justifying with the piston crown cross section is a symmetry, and thickening layer is inwardly arranged, piston lobe gear can be installed better, outwards consistent with the curved surface of piston side, cylinder head will have two concane gaps correspondingly.Inner chamber under the cylinder head is that synthetic one of the hemisphere cavity groups that firing chamber and piston crown sink is removed thickening layer ball cavity outside, the piston lobe can back and forth rotate around axle interior, the piston lobe links to each other by axle with respective pistons lobe gear, piston lobe gear parts band tooth, the number of teeth what so that the piston lobe can half-twist exceeds, the tool tooth bar segment length of connecting rod one end also can be exceeded by half-twist with the piston lobe, the connecting rod key that the connecting rod the other end connects is box-shaped, the tool handle, be with spring on the handle, the connecting rod key can be done moving of small distance.A flexible device of tool is set on the connecting rod, when extenuating work roughly, the connecting rod key moves on draw runner He in the draw runner track.The draw runner long strip, be fixed in the crankcase, length is greater than piston stroke, establishes the draw runner track on the draw runner, should have mutually in a draw runner track key is placed in, draw runner track tool handle, be with spring on the handle, its handle presses closer the thin and thick wheel, and the thin and thick wheel can be installed on the camshaft, thin, the thickness portion half and half of thin and thick wheel come the variation of control piston with this.

Deformed piston and a series of parts thereof have advantages such as simple in structure, easy to manufacture, easy for installation, and prior art all can production and processing.Also possesses power performance, economic performance actively effect such as good simultaneously.

Below in conjunction with accompanying drawing the utility model is further described

During air inlet, Deformed piston body ［ 25 ］ is operation downwards, draw runner track key ［ 14 ］ is under the effect of thin and thick wheel ［ 13 ］ and spring ［ 10 ］, sink and form a draw runner track ［ 15 ］, connecting rod ［ 9 ］ and connecting rod tool rack segments ［ 6 ］ be also operation downwards under the drive of piston, when the lower fulcrum that runs to draw runner track ［ 15 ］［ 24 ］, connecting rod strong ［ 12 ］ and connecting rod ［ 9 ］ are under the restriction of draw runner track ［ 15 ］, can not move with piston again, but piston must move downwards, at this moment, connecting rod tool rack segments ［ 6 ］ drives piston lobe gear ［ 3 ］, ［ 4 ］ and piston lobe ［ 1 ］, ［ 2 ］ rotation makes piston lobe ［ 1 ］, ［ 2 ］ rotate in the piston.

When compression, acting, draw runner track key ［ 14 ］ is full of draw runner track ［ 15 ］ and forms a plane with draw runner ［ 16 ］ under the effect of thin and thick wheel ［ 13 ］ and spring ［ 10 ］, connecting rod key ［ 12 ］ is ejected draw runner track ［ 15 ］ and slides in the plane, thereby inoperative piston lobe ［ 1 ］, ［ 2 ］, the piston lobe is still in piston.

During exhaust, thin and thick wheel ［ 13 ］, thin part heads on the handle ［ 11 ］ of draw runner track key, and under the effect of spring ［ 10 ］, lake bar track ［ 14 ］ sink and forms draw runner track ［ 15 ］, connecting rod key ［ 12 ］ enters draw runner track ［ 15 ］ simultaneously, upwards operation under the drive of piston, when running to draw runner track top dead center ［ 23 ］, the connecting rod operation that can not make progress again, thereby start piston lobe ［ 1 ］ again, ［ 2 ］ rotate to outside the piston it, carry out exhaust by force.
