Abstract

The utility model discloses a piston ring device with oil saving and efficiency increase for gasoline engines and diesel engines. The utility model is composed of a piston body, a piston ring, an oil ring, etc. The both ends of the connecting opening of the original piston ring (1) are lengthened with 4-10 mm, and then an upper lapping and pulling end (2) and a lower lapping and pulling end (3) are formed. The upper lapping and pulling end (2) and the lower lapping and pulling end (3) are correspondingly made into a closing device of a connecting opening slope lapping and pulling plane. The utility model achieves the purposes of oil saving, efficiency increase and horsepower increase. The utility model has the advantages that the utilization rate of the air cylinder improves more than 50%, and the horsepower increases more than 10%. The utility model is suitable for gasoline engines, diesel engine motorcycles, automobiles, diesel engines and ships.

Description

Four-stroke petrol and diesel oil machine piston ring shutoff device

The utility model belongs to piston ring, particularly a kind of four-stroke petrol and diesel oil machine piston ring shutoff device.

Phenomenons such as the handing-over mouth of existing four-stroke petrol and diesel oil machine piston ring is flat mouthful gapped device, and piston ring uses wearing and tearing back piston ring opened gap along with increase, causes motor power to occur and reduces, and horsepower is not enough, and consumable lubricating oil is many.Often cause more rering, cylinder also will carry out boring after wearing and tearing increase, and the size of oversize piston ring could normally be used simultaneously.

It is a kind of simple in structure, reasonable in design that the purpose of this utility model is to provide, and can improve the utilization ratio of cylinder, soups, and prolongs the piston ring four-stroke petrol and diesel oil machine piston ring shutoff device in working life.

Technical solution of the present utility model is such, comprise taking and drag end by piston body, piston ring, oil ring, interface, taking up and down of 4-10mm of lengthening dragged end at the two ends of former piston ring joint, the shutoff device that drags the plane is taken on the corresponding interface inclined-plane of making of upper and lower end, and consistent with former piston ring of the thickness that drags and width taken at two ends.Piston ring can be got rid of the ill effect that conventional piston ring opened gap causes fully after improving, make piston ring keep excellent sealing performance.

The utility model has the advantages that: simple in structure, reasonable in design, easy to manufacture.Easy to install, can make piston ring keep not having opened gap, the opening of the handing-over mouth of maintenance piston ring is taken towing a sling and is closed state, has most desirably solved machine oil and has penetrated the firing chamber easily.Have and double the working life that prolongs piston ring abovely, the utilization ratio of cylinder improves more than 50%, and horsepower increases more than 10%.Also have cost low, benefit is big, is easy to popularize, and the four-cycle, single-cylinder and the multi-cylinder gasoline and diesel engine piston ring group device that are suitable for the homemade import of various different models are used, and particularly are suitable for automobile, motorcycle, agricultural equipment Diesel engine, the first-class use of ship.

It is such that structure of the present utility model constitutes:

Fig. 1 is a piston ring parts drawing plan view of the present utility model.

Fig. 2 is a piston ring parts drawing worm's eye view of the present utility model.

Fig. 3 loads onto piston back part topology view for piston ring of the present utility model.

Among Fig. 1, Fig. 2, Fig. 3.Piston ring (1), on take and drag end (2), take and drag end (3), oil ring (4), piston body (5) down.

Most preferred embodiment of the present utility model is such, with reference to shown in Figure 1, on former piston ring (1) interface two ends (2,3) lengthening corresponding beveling of 4-10mm or taking of plane drag the formula shutoff device, promptly be, take and drag end (2) to drag the relative interface inclined-plane of making of end (3) to take the shutoff device that drags the plane with taking down.Taking up and down and dragging the length of end (2,3) is to decide according to the size of piston ring.Corresponding the taking of little piston ring drags two ends (2,3) length to get 4mm approximately, and corresponding the taking up and down of big piston ring drags end (2,3) length to get 10mm approximately and be advisable.When piston ring (1) is put into the annular groove of piston body (5), keeping taking of two ports to drag by required the opening or close state and can both closely join of piston up-down like this, it does not directly upwards leak gas can to keep piston ring at least.The handing-over of required state is taken and is not had opened gap when dragging sealing or the required maintenance of clutch exhaust to use when utilizing self elastic force of piston ring just can keep piston ring (1) folding.Solve machine oil and penetrated firing chamber habituation easily.

Claims

A kind of four-stroke petrol and diesel oil machine piston ring shutoff device, comprise by piston body (5), piston ring (1), oil ring (4), take and drag end, it is characterized in that take on the lengthening 4-10mm of the interface two ends of former piston ring (1) drag end (2) and under drag end (3), take up and down and drag the corresponding interface inclined-plane of making of end (2,3) to take the shutoff device that drags the plane.
