Abstract

The invention discloses a novel piston ring and belongs to the mechanical field. The novel piston ring comprises an upper ring (O1) and a lower ring. The lower ring comprises an outer ring (O2) and an inner ring (O3) of the same thickness. The upper ring (O1), the outer ring (O2) and the inner ring (O3) are concentric. The external diameter of the inner ring (O3) is equal to the internal diameter of the outer ring (02), and the external diameter of the upper ring (O1) is equal to the external diameter of the outer ring (O2). The upper ring (O1), the outer ring (O2) and the inner ring (O3) are provided with a ring opening (C1), a ring opening (C2) and a ring opening (C3) respectively, and the ring opening (C1, C2 and C3) are staggered. The novel piston ring overcomes the defect that an existing engine cylinder leaks air to a crank case, can greatly improve the performance of an engine, and enables the engine to reach the effects of energy conservation and emission reduction.

Description

A kind of novel piston ring

Technical field

The present invention relates to mechanical field, particularly a kind of novel piston ring.

Background technique

Present piston ring, each piston ring groove fills a piston ring, and due to the impact by metal heat-expansion shrinkage, piston ring must stay certain opened gap, when engine compressed air is with acting, be inevitable toward crankcase blow-by, along with piston ring and cylinder bucket constantly wear and tear, collar extension can strengthen air leakage, the power of serious reduction motor, the consumption of continuous increase fuel oil, leaks into waste gas and the burning particles thing of crankcase, and machine oil Quick Oxidation is gone bad.Crankcase waste gas pipe is connected with engine air inlet tube, and a large amount of waste gas is inhaled into cylinder combustion again, and the fresh air causing motor to suck reduces, and is equivalent to motor and works under the state of anoxic, and engine combustion efficiency declines.Cause the work vicious circle of motor thus.

Gas leakage not only engine power declines, and toxic emission can strengthen the dynamics of befouling environment.The gas that collar extension is leaked knocks cylinder along piston impact piston inside cylinder, adds the wearing and tearing in cylinder, also add the noise of motor.A large amount of high temperature and high pressure gas forms oil vapor the machine oil of crankcase.Oil vapor can enter engine air inlet tube along with flue gas leading, sucks the situation that cylinder combustion defines a large amount of consumption of lubricating oil of engine motor oil.

Summary of the invention

In order to make up above deficiency, the invention provides a kind of novel piston ring that can not cause toward crankcase blow-by situation.

Technological scheme of the present invention is:

A kind of novel piston ring, comprise pressed on ring O1 and lower ring, described lower ring comprises outer shroud O2 and inner ring O3, and the thickness of described outer shroud O2 and inner ring O3 is equal; Described pressed on ring O1, outer shroud O2 and inner ring O3 are arranged with one heart; The external diameter of described inner ring O3 equals the internal diameter of outer shroud O2, and the external diameter of described pressed on ring O1 equals the external diameter of outer shroud O2; Described pressed on ring O1, outer shroud O2 and inner ring O3 are arranged respectively ring open C 1, ring open C 2, ring open C 3; Described ring open C 1, ring open C 2, ring open C 3 stagger setting.

Preferably, the internal diameter of described inner ring O3 equals the internal diameter of pressed on ring O1.

Preferably, described ring open C 2 and ring open C 1 stagger 90-180 °.

Further, described ring open C 2 staggers 180 ° with ring open C 1.

Preferably, described ring open C 2 and ring open C 3 stagger 30-120 °.

Further, described ring open C 2 staggers 90 ° with ring open C 3.

Preferably, the thickness of described pressed on ring O1 is 2/3-2 times of outer shroud O2 thickness.

Further, the thickness of described pressed on ring O1 is equal with the thickness of outer shroud O2.

Piston ring of the present invention, pressed on ring O1, outer shroud O2 and inner ring O3 are placed in same annular groove.Use piston ring of the present invention, during engine compressed air, air is kept off from the direction that ring open C 1 is descending by lower loop resistance.Air enters (piston ring axial clearance) inside upper and lower ring along ring open C 1.Ring open C 2 is closed by pressed on ring O1 above with ring open C 3.The inner side mouth of ring open C 2 is by inner ring O3 outer side seal, and ring open C 3 collar extension is sealed by outer shroud O2.Lower ring lower plane is again by piston ring groove plane sealing, and the gas of firing chamber that causes sealed to each other is completely enclosed, overcome now all cylinders toward crankcase blow-by phenomenon.

Beneficial effect of the present invention is:

1. what suck during engine charge is air, and oxygen content is high, and abundant with fuel oil mixed combustion, thermal effect is high, and tail gas is environmental protection more;

2. air tight when cylinder air compression and acting, Engine torque increases;

3. simplify engine exhaust gas passage, Pcv valve can be removed, and saves motor manufacture cost;

4. machine oil is not subject to the pollution of the particulate matter of waste gas and burning, better improves the lubricating condition of motor, increases service life of aeroengine, change engine oil cycle stretch-out more than 1 times.The filter core of machine oil can be made fine and closely woven stainless steel filtering net and just forever use not change engine oil filter core, a large amount of saving engine maintaining cost;

5. engine intake passage and valve do not cause the intake resistance of motor to reduce power forming carbon distribution because of machine oil steam, save maintenance cost;

6. do not have collar extension to leak gas, piston is stable up and down, and wear and tear little, noise is low, prolonged engine life;

7., along with the running of motor, the opened gap of piston ring and the wearing and tearing of cylinder strengthen also can not leak gas, and power is unattenuated;

8. low engine speed moment of torsion is large, can the slow-speed of revolution speeds that makes vehicle higher, saves fuel oil in a large number, reduces energy consumption;

9. piston can one compression ring, one oil ring, reduces depth pistion, saves motor manufacture cost;

10. this associative ring, also can be arranged on air compressor, on hydraulic equipment, high temperature resistant, wear-resistant; Applied range;

11. all vehicle new engines all can install this piston ring, and after installing, power increases at once.
