"CNG" Stands for _____.

Compressed Natural Gas

The correct answer is option 2. Compressed Natural Gas.

CNG stands for Compressed Natural Gas.

Compressed Natural Gas (CNG) is a type of fuel that primarily consists of methane gas stored at high pressure. It is obtained from natural gas reservoirs or as a byproduct of oil extraction. CNG is compressed to reduce its volume and increase its energy density, allowing for more efficient storage and transportation.

CNG is widely used as an alternative fuel for vehicles, particularly in areas where it is abundant and accessible. It is considered a cleaner and more environmentally friendly fuel compared to traditional gasoline or diesel because it produces fewer emissions when burned. Additionally, CNG combustion releases fewer pollutants such as carbon monoxide (CO), nitrogen oxides (NOx), and particulate matter.

In vehicles, CNG is stored in high-pressure cylinders onboard the vehicle and delivered to the engine, where it is mixed with air and combusted in the combustion chamber to produce power. Many vehicles, especially public transportation fleets and commercial vehicles, use CNG as a cost-effective and environmentally sustainable fuel option.

Overall, CNG provides an alternative to conventional petroleum-based fuels, offering potential benefits in terms of reduced emissions, improved air quality, and energy security.
