Definitions
- the utility model relates to a piston ring of an internal combustion engine.
- the opening of the piston ring is staggered 180 ° to prevent or reduce the leakage of high-temperature gas, while large-volume cylinders often use multiple rings to still not prevent the leakage of high-temperature gas, especially after passing through After prolonged use, the piston ring and the cylinder wear, causing the opening gap of the air ring to increase, the leakage of high-temperature gas increased, the machine power ⁇ and the fuel consumption increased sharply.
- P had previously designed a production product
- the giant of the utility model is to design a P-type energy-saving and environmentally-friendly piston ring with an inclined surface.
- the two extension parts of the ring body P can be squeezed together in an inclined surface to block high gas. Drainage channel effectively guarantees the tightness of the cylinder combustion chamber, increases the cylinder compression pressure, improves the dynamic performance of the machine, and reduces exhaust emissions to save energy and protect the environment.
- the inclined surface energy saving and environmental protection type piston ring has a ring body with an opening P, and its structural feature is that the opening P has an extension of 3-5 mm in length and its Another
- extension portion has a ring body bottom retaining surface extending from the inner side of the ring body to the outside by 0.75-1 mm, ⁇ ⁇
- the overlapping surface of the extension portion and the overlapping portion is a corresponding inclined surface that forms an angle with the bottom surface of the ring body, thereby forming an inclined surface bonding structure with two ends opened P.
- the structure 1 of the present invention has a ring body 1 with an opening ⁇ , and the length of one of the end openings is
- extension 2 or 3 and the other end is a lap portion 3 or 2 of the corresponding length; see Fig. 3, the extension 2 or 3 has an extension of 0.75 outwards with reference to the inside of the ring body 1 -1 mm ring body bottom surface retaining surface 10; see Figures 3 and 4, the overlapping surfaces 4 and 5 of the extension portion 2 3 and the overlapping portion 3 or 2 correspond to the angle between the bottom surface of the ring body 1
- the beveled surface thus forms the beveled structure with open ends
- the design principle of the utility model is that a ring is placed in each cylinder of the piston in the same manner as in the conventional method, and the piston is placed in the cylinder.
- the overlapping surface 4 of the extension portion 2 is attached to the overlapping portion 3.
- the overlapping surface 5 is above, so there is only one gap in the ring body when viewed from above. Since the inner side of the extension part 2 has an edge of 0.75-1 mm, the lap surface 4 fits on the lap surface 5, and the sloping surface of the lap portion 1 mm is close to the cylinder. wall.
- the left side of the interface is blocked by the overlap surface 4 of the extension 2 and the right interface is blocked by the overlap surface 5 of the overlap portion 3. Therefore, the entire ring
- the body forms a complete circle, and there is no channel for leaking high-temperature gas.
- the utility model is a process and has a simple structure.
- "Bevel-fitting energy-saving and environmentally-friendly piston ring” which solves the problem of leakage of high-temperature gas that has trapped people's piston ring openings for many years.
- the compression pressure of the combustion chamber is increased, so that the fuel oil can be fully burned, and the effect of energy saving and environmental protection is achieved, and the power of the engine is also increased.
- FIG. 1 is a plan view structure of the present invention (where the diagonal line at the end opening portion is the inclined surface of the overlapped portion;
- Figure 2 is the front view structure of the utility model (where the diagonal line at the end opening is the inclined surface of the extension);
- Figure 3 is an enlarged view of the ring body opening extension
- Figure ⁇ is an enlarged view of the overlapping part of the ring body opening.
- the inner diameter of the cylinder is 78.01 mm, and the outer diameter of the piston is 77.91 mm.
- the original static compression force is 9kg / cm 2.
- the static compression pressure reaches 11.4kg / cm 2 (90% of the new car).
- the flexural strength reaches 1870Mpa, far exceeding the national standard of 1300Mpa, which solves the strength problem of the bevel part of the bevel.
- the present invention The ring body with (extended) joints, the upper and lower lap faces 4 and 5 of the extension and lap sections 2 or 3 respectively form an angle of 20-25 ° with the bottom edge of the ring body, and the lap faces 4 and
- the width of 5 is the same: ring body width X 0.818, length is also 3-5mm, the ring body cutout forms the upper section 6 of the extension portion and the lower section 9 of the lap portion, and the bevels at both ends of the processing opening increase the lower section 7 With the overlapping section on the section 8 while reducing the mountain
- the gap between the upper section 6 of the extension section and the upper section 8 of the lap section and the lower section 7 of the extension section and the lower section 9 of the lap section are both 0.2-0.3mm.
