What size tank is used for the CNG conversion of the Baojun 510?
4 Answers
Baojun 510 CNG conversion uses a 75L tank. Benefits of CNG conversion: Natural gas mixes easily and uniformly with air in the engine, resulting in more complete and cleaner combustion with less carbon buildup. It has good anti-knock properties and doesn't dilute lubricating oil, significantly reducing wear on engine cylinder components. This extends both engine lifespan and lubricant service intervals. Drawbacks of CNG conversion: Since gasoline engines are originally designed for liquid fuel, the different compression ratios between gasoline and CNG can cause significant engine damage after conversion. Prolonged CNG use can be harmful to the vehicle. Typically, CNG-converted vehicles cannot be restored to their original gasoline-only configuration.
I've been converting cars to natural gas for several years. For compact SUVs like the Baojun 510 with limited space, most people find a 60-liter tank most suitable. With my 55-liter tank, I get about 300 km of city driving range, with fuel costs half that of gasoline, saving significant expenses. However, note that the tank occupies part of the trunk space after conversion - choosing too large (e.g. 70L) will squeeze luggage space, while too small (e.g. 45L) means short range requiring frequent refills. Conversion shops will help select safe capacity based on vehicle structure - an overly heavy tank affecting braking performance is problematic. Remember to avoid parking in direct sunlight and regularly check tank seals for leaks - safety comes first. Conversions are more cost-effective in areas with good CNG station coverage. Overall, the Baojun 510 offers good value for gas conversion.
The selection of gas tank size depends on technical factors, including vehicle space and daily needs. The Baojun 510 has a compact trunk, and tanks with 50 to 70-liter capacity are typically recommended. A 70-liter tank can provide a range of nearly 400 kilometers but occupies more space, making cargo loading inconvenient; a 50-liter tank saves space but only covers about 250 kilometers, suitable for short trips. During modification, calculate the changes in vehicle weight—too large a tank can affect vehicle balance and even braking distance. Regulations also limit the maximum volume ratio, so avoid exceeding the standard. Professional modification shops can assess your daily driving distance and recommend an appropriate size, such as choosing a 65-liter tank for a balance between range and convenience if you frequently drive long distances. Additionally, consider the distribution of gas stations to ensure convenient refueling. After modification, pay attention to stable tank pressure and regular maintenance to avoid aging and rust from long-term use.
Safety should always be the top priority when modifying a gas system. For a small car like the Baojun 510, the gas tank shouldn't be too large—50 to 60 liters is sufficiently safe. A larger tank increases risks such as leakage from bumps. Legally, the tank volume must not exceed 30% of the vehicle's space to comply with regulations. A 60-liter tank is adequate for daily driving of about 300 kilometers; anything larger, like 70 liters, can make the car unstable and affect driving. When using the car, park in a shaded area to avoid heat, as excessive heat can increase pressure and pose dangers. Before and after modification, check that all fixtures are secure and inspect the seals every six months. Choose a reputable shop to ensure installation quality. Given the limited space in the Baojun 510, avoid opting for an overly large capacity.
