| titleOfInvention | Combination oil ring |
| abstract | In order to provide a combined oil ring that prevents oil sludge from adhering and accumulating even during long-term engine operation, and does not cause sticking between components, and can maintain an excellent oil control function. The combined oil ring consisting of a pair of upper and lower side rails supported by the spacer expander is coated with a fluorine-containing film on at least the side surface of the side rail facing the spacer expander, and the spacer expander is coated with a metal film. Cover. Here, the contact angle (θ 1 ) of the paraffinic lubricant at 150 ° C. of the portion of the side rail covered with the fluorine-containing coating is 50 ° or more, and 150 ° C. of the portion of the spacer expander coated with the metal coating. The contact angle (θ 2 ) of the paraffinic lubricating oil in is set to 10 to 50 °, and the difference (θ 1 −θ 2 ) between θ 1 and θ 2 is set to 30 ° or more. |
