2. Hot discussion background
1.Policy promotion:Many places have introduced policies to encourage new energy vehicles, but some car owners choose to modify rather than replace their vehicles due to cost issues.
2.Oil prices rise:Recently, oil prices have been rising continuously, natural gas prices are relatively stable, and the economics are outstanding.
3.Environmental controversy:Whether modified vehicles can really reduce pollution has become a focus of controversy.

|---|---|---|
| Environmental protection | Natural gas burns cleaner and reduces particulate matter emissions | Improper modification techniques may lead to leakage risks |
| Economy | Fuel costs reduced by 30%-50% | The initial modification cost is high (about 10,000-20,000 yuan) |
| security | Modifications made by regular manufacturers can pass quality inspection | Illegal modifications pose an explosion hazard |
3. Typical case analysis
1.Large-scale modification of taxis in Xi'an:Local media reported that more than 5,000 taxis have been converted to gas in the past three years, saving an average of 24,000 yuan in fuel costs annually.
2.Private car spontaneous combustion incident:A case of spontaneous combustion of a modified car exposed on a short video platform received more than 500,000 likes in 10 days, raising questions about its safety.
4. Expert opinions
Li Ming, an expert from the China Society of Automotive Engineers, pointed out: "Compliance modification must meet three points:① Use national certification kits; ② Construction in the filing agency; ③ Pass the inspection after modification. "At the same time, it was emphasized that the newly revised "Motor Vehicle Registration Regulations" in 2023 clearly requires that illegal modifications will face fines and be ordered to return to their original state.
5. Future trends
According to industry forecasts, with technological advancement and improved supervision, the legal modification market may grow to 2 billion yuan in 2024. However, the environmental protection department reminds that"Changing the old to the gas" is only a transitional plan, and ultimately still need to transform to pure electric vehicles.
Conclusion:The phenomenon of "replacement of old vehicles with gas engines" reflects the trade-off between environmental pressure and economic benefits among car owners. If consumers consider modification, they must choose formal channels and pay attention to local policy trends. The statistical period of the data in this article is from November 1 to 10, 2023, and the information comes from public online platforms.
