| 2. Appearance inspection | Check the fixing condition of body and gas device | The gas bottle must be firmly fixed without signs of rust or leakage |
| 3. Security inspection | Braking, lighting, chassis and other regular items | Consistent with the testing standards for ordinary fuel vehicles |
| 4. Gas system inspection | Special testing of air tightness, pressure valves, pipelines, etc. | A "gas vehicle modification certificate" is required |
| 5. Exhaust gas detection | Exhaust emission detection in gas mode | Some areas are exempt from fuel mode exhaust gas testing |
2. Necessary materials for annual review of oil-to-gas vehicles

4. Answers to Frequently Asked Questions about the Annual Review of Oil-to-Gas Vehicles
1.Q: Can a privately modified vehicle pass the annual inspection?
A: Absolutely not. The modification must be carried out by a qualified modification factory and the "Gas Vehicle Modification Certificate" must be obtained before the annual review can be carried out.
2.Q: How to deal with expired gas bottles?
A: The service life of gas bottles is generally 15 years. Before expiration, they need to be tested by a designated agency. If they pass the test, they can be extended for use. If they fail, they must be replaced.
3.Q: The main reason for failing the annual review?
A: Data shows that 80% of failed cases are due to gas system leaks (55%) and incomplete modification qualifications (25%).
4.Q: Is it feasible to conduct an annual review in another location?
A: Yes, but the qualifications of the testing station need to be confirmed in advance, and the modified equipment registration information needs to be available on the national network.
5. Professional advice
1. It is recommended to complete the vehicle registration change within 3 months after modification to avoid incomplete information during the annual review.
2. Check the gas system regularly. It is recommended to conduct professional inspection every 5,000 kilometers.
3. Keep all modification tickets and certificates, electronic backup is more secure.
4. Pay attention to local policy changes. Some cities have begun to implement stricter emission standards.
Through the display and detailed explanation of the above structured data, I believe that car owners will have a clearer understanding of the annual review process for oil-to-gas vehicles.
