A CNG (Compressed Natural Gas) powertrain is an eco-friendly alternative to traditional gasoline and diesel engines. It operates by using natural gas stored at high pressure, which is then injected into the engine’s combustion chamber. This type of powertrain is known for its lower emissions, producing significantly fewer pollutants such as CO2 and particulate matter compared to conventional fuels. Vehicles equipped with CNG powertrains are not only environmentally friendly but also cost-effective, as CNG is often cheaper than gasoline or diesel¹. Additionally, CNG engines tend to have a longer lifespan due to the cleaner combustion process, which reduces engine wear and tear. The adoption of CNG powertrains is growing, especially in regions with abundant natural gas resources and supportive infrastructure. Automakers are increasingly offering CNG variants of popular models, providing consumers with more choices for sustainable transportation. Despite the benefits, the main challenges include the limited refuelling infrastructure and the reduced driving range compared to gasoline vehicles. However, advancements in technology and increasing investments in CNG infrastructure are expected to mitigate these issues, making CNG powertrains a viable option for the future of green mobility.
