How to Convert a Car from Gasoline to CNG?

This modification involves minimal changes to the vehicle, but the combustion and fuel efficiency may be slightly worse. It mainly involves installing a gas cylinder and a pressure reducer in the available space. The difference from the previous method is that instead of adding a mixer at the throttle, it involves drilling holes in the intake manifold to install nozzles for injecting natural gas directly, which requires more electronic components.
Gas conversion, simply put, means modifying your car to run on natural gas, and it should be done by a certified conversion shop. First, they'll assess if your car is suitable for conversion, like checking if the engine model is compatible. Then, they'll install a gas tank, usually made of aluminum or steel, mounted on the chassis or in the trunk without taking up too much space. Next comes the fuel injection system, connected to the existing fuel system, with a switch added to toggle between gas and fuel. During tuning, they'll ensure all seals are tight to prevent leaks, and then you'll need to register the modification with the DMV. The conversion might take about three days. Daily use on gas might slightly reduce power, but it's fine for city driving. Remember to choose reliable parts to avoid affecting your car's lifespan, and after the conversion, enjoy the savings.
Thinking about converting your car to run on gas? Let me share some money-saving tips. The conversion usually costs between six to seven thousand to over ten thousand yuan, depending on the car model and the quality of the parts. Natural gas is significantly cheaper than gasoline, saving you a few cents per kilometer. If you drive a lot, you can recoup the cost in about six months. Plus, some areas offer subsidies, making it even more cost-effective after application. For maintenance, the gas tank needs to be inspected every two years at a low cost. Gas stations are more common in urban areas, but less so in smaller towns. Overall, you can save one to two hundred yuan on fuel costs each month. After choosing a certified conversion shop, don’t forget to remind the technician to install fuses and protective devices for safer daily driving.
The biggest concern before modification is safety. Let me share my personal experience: choosing a certified workshop is crucial, and using certified gas cylinders and systems is a must. After installation, always check for gas leaks at the connections before driving, and avoid idling in the garage. Follow proper procedures at refueling stations, and never attempt DIY repairs. Regularly visit the workshop for pressure tests, and replace gas cylinders when they reach their expiration date. If you smell anything unusual while driving, stop immediately and inspect. Safety comes first—modifications can save money, but don’t risk accidents by opting for cheap, unqualified workshops.
