Abstract
The invention relates to an engine piston which has one groove and double rings improved on a traditional single-ring piston. Openings of the piston rings are installed in a stagger way; and in order to prevent up-down aligning in the motion process, a positioning device is arranged between the double rings to ensure that aligning can not occur forever so as to thoroughly solve the problem of sealing effect and increase the cylinder pressure. Same fuel (gas) can generate increased explosive power under the condition of large cylinder pressure, and high-pressure gas after the explosive can not be released so that the power is doubled; on the other hand, a lubricating oil film which can be also called as an active oil film is clamped between the double rings all the time and has a better lubricating effect than a traditional single ring, therefore, the power is tripled. In addition, the noise is reduced, and the service life of the piston is prolonged.
Description
Technical field
The present invention relates to a kind of sealing device of engine cylinder.
Background technique
The casing airtight of internal-combustion piston engine is one of energy-efficient performance key factor of motor, and seal is mainly seen the sealability of piston ring.But the opening of at present traditional piston ring when Piston Compression fuel oil-gas from opening miss and make that the cylinder pressure drop is low, waste fuel and befouling environment; When fuel blast back piston rollback pressurized gas can miss from opening again power is reduced, oil pollution speeds up, piston temperature raises reduces working life.The present invention changes original traditional monolithic piston ring into a groove biplate piston ring, the opening arranged in dislocation of every loop, for preventing that it from occurring counterpart up and down again in movement process, so between the biplate ring, must there be positioning device to reach never counterpart, thoroughly solved the sealing effect problem, cylinder has been pressed increase.Identical fuel oil (gas) presses the explosive power that is produced under the big situation also to increase simultaneously at cylinder, and the pressurized gas after the blast can not run away again, and power has obtained two increasing; Between the biplate ring, clip lubricant film on the other hand all the time, can be described as the oil film of " active " on mechanism, lubrication effect is than the much better frictional force that reduced of conventional one-piece ring, and power has obtained the enhancing of three aspects, noise also decreases, and also prolong working life thereupon.
Summary of the invention
In order to improve available engine casing airtight problem, the present invention has adopted and has changed original traditional monolithic piston ring into a groove biplate piston ring, the opening arranged in dislocation of every loop, for preventing that it from occurring counterpart up and down again in movement process, so between the biplate ring, must there be positioning device to reach never counterpart.
For achieving the above object, the present invention takes following design proposal: a kind of sealing device of engine cylinder, it comprises: cylinder, piston ring is characterized in that described piston ring is the biplate structure.
The biplate opening dislocation of described piston ring is arranged.
Relative position is fixed with the inclined-plane between the biplate of described piston ring.
Relative position is fixed with the tenon rivet clasp between the biplate of described piston ring.
Relative position dowel fixes between the biplate of described piston ring.
Relative position is fixed with bayonet socket between the biplate of described piston ring.
The biplate of the above piston ring adopts stainless steel material.
The biplate of the above piston ring adopts the vanadium steel material.
The biplate of the above piston ring adopts the wolfram steel material.
The biplate of the above piston ring adopts the titanium steel material.
Advantage of the present invention is:
A kind of sealing device of engine cylinder of the present invention changes original traditional monolithic piston ring into a groove biplate piston ring, the opening arranged in dislocation of every loop, for preventing that it from occurring counterpart up and down again in movement process, so between the biplate ring, must there be positioning device to reach never counterpart, thoroughly solved the sealing effect problem, cylinder has been pressed increase.Identical fuel oil (gas) presses the explosive power that is produced under the big situation also to increase simultaneously at cylinder, and the pressurized gas after the blast can not run away again, and power has obtained two increasing; Between the biplate ring, clip lubricant film on the other hand all the time, can be described as the oil film of " active " on mechanism, lubrication effect is than the much better frictional force that reduced of conventional one-piece ring, and power has obtained the enhancing of three aspects, noise also decreases, and also prolong working life thereupon.
