7 Questions To Understand CNG Automotive Modification

Q: Are there many installations of CNG now?
A: There are all kinds of cars available. Jetta, Santana, and Fukang don't need to be mentioned. Passat, Excelle, Sail, Chery, Hyundai, as well as various SUVs and operational vans, there are all types of cars available. A staff member from a professional modification factory located in Xindu said that there are now around 10 vehicles modified every day, with a maximum of 20 vehicles, which is 3-5 times more than before.

Q: Does using compressed natural gas after switching to CNG have an impact on engine lifespan?
A: This doubt is unnecessary. Firstly, clean natural gas is a clean energy source that produces only carbon dioxide and water after combustion, making it more environmentally friendly than burning gasoline. Moreover, the relevant departments now have very strict requirements for the dehydration and desulfurization process of gas stations, which eliminates the corrosion of engines caused by harmful chemicals produced by the combustion of natural gas containing sulfur and water. Another benefit of using CNG is that it effectively avoids the problem of engine carbon buildup caused by using gasoline.

Q: What is the cost of modifying CNG?
A: The complete set of CNG modification components generally includes gas pressure reducing valves, fuel injection simulation devices, electronic control systems, conversion switches, and so on, in addition to gas cylinders. The total price of these complete sets of accessories varies depending on the place of origin, with Sino foreign joint ventures and domestically produced ones generally being 300 to 400 yuan less. There is also an important safety reminder: When modifying CNG devices for vehicles, it is necessary to go to a professional organization with modification qualifications recognized by the Provincial Quality Supervision Bureau. During the modification process, you must also check whether all the components used are brand new. Do not only try to use old gas cylinders that have been replaced by others at a low cost, as this will not only bring significant safety hazards, but also may encounter the embarrassment of gas stations refusing to add gas.

Q: Are there any specific requirements for driving after modifying CNG?
A: Before starting the car for the first time in the morning, set the fuel to gas switch to the gasoline side and start it with gasoline. Wait until the water temperature is normal before using CNG. It's best to use gasoline again before parking at home at night to ensure smooth fuel flow the next day. It is recommended to use gasoline to drive for about 5 kilometers each morning and evening. In addition, it is best to place the transfer switch on the fuel side when parking, so that the high-pressure valve in the CNG system will close to prevent slow air leakage at night.

Q: Do I need to go to the traffic management department to complete the procedures after modifying the CNG?
A: Required. Generally, the application should be submitted to the vehicle management office first and can only be modified after being registered. Going to a regular modification factory to handle the general procedures will be very complete.
