What does CNG stand for?

CNG stands for Compressed Natural Gas. This term refers to natural gas that has been compressed to less than 1% of its volume at standard atmospheric pressure. CNG is primarily composed of methane and is utilized as a cleaner alternative to gasoline and diesel in vehicles. It is favored for its lower emissions compared to traditional fossil fuels, making it an environmentally friendly option for fuel in transportation.

The other options, while they contain terms related to natural gas or gases, do not accurately describe what CNG stands for. Compressed Nitrogen Gas refers to nitrogen that has been compressed for various industrial applications but is not relevant in the context of fuel for vehicles. Clean Natural Gas might imply a notion of natural gas being environmentally friendly, but it is not an established acronym. Controlled Natural Gas suggests some management or regulation aspect of natural gas but lacks precision in defining what CNG actually represents in the context of fuel systems.
