Question

what is compressed natural gas​

Answer 1

Answer:

Compressed natural gas (CNG) vehicles operate much like gasoline-powered vehicles with spark-ignited internal combustion engines. The engine functions the same way as a gasoline engine. ... The fuel-air mixture is then compressed and ignited by a spark plug.

Answer 2

Compressed natural gas (CNG) (methane stored at high pressure) is a fuel that can be used in place of gasoline, diesel fuel and liquefied petroleum gas (LPG). CNG combustion produces fewer undesirable gases than the aforementioned fuels.
