What does CNG stand for?

CNG stands for Compressed Natural Gas. This is a type of fuel that is made by compressing natural gas, which primarily consists of methane, to a high pressure. By compressing it, the gas occupies less volume, making it suitable for storage and use in vehicles. CNG is commonly used as an alternative to gasoline or diesel fuel in vehicles which can help reduce the emissions of pollutants.

Understanding this is essential as it highlights the importance of alternative fuels in the context of environmental sustainability and developments in automotive technology. Other choices refer to variations that do not accurately describe the compressed state of natural gas used as a vehicle fuel. For instance, 'Condensed Natural Gas' suggests a process that is not typically used in this context, while 'Clean Natural Gas' may imply a focus on emissions without specifically addressing the compression aspect. 'Composite Natural Gas' introduces a terminology that does not align with standard definitions in the industry. Thus, recognizing CNG specifically as Compressed Natural Gas is crucial for those involved in vehicle rescue and environmental management.
