 Compressed Natural Gas

Compressed Natural Gas

  • CNG stands for Compressed Natural Gas.
  • It mainly comprises methane gas which can produce engine power after it's mixed with air and fed into an engine's combustion chamber. So, it is used as a substitute for Diesel, Petrol and Propane/LPG.
  • It's effective to control air pollution because it produces fewer undesirable gases in comparison to Diesel, Petrol and LPG. So it's more environment-friendly than other fuel products.
  • It's safer than its other substitutes within the case of the spill because it's lighter than air and disperses quickly when released.

Brief History of CNG

  • The use of natural gas as a fuel for vehicles was introduced within the late-1800s.
  • The first natural gas Vehicle was patented within the USA and soon after the Second war, Italy and various other European countries adopted CNG as a primary fuel.
  • CNG is found over oil deposits. It can also be collected from landfills and wastewater treatment plants.
  • It's made by compressing gas to but one percent of its standard atmospheric pressures.
  • It's stored and distributed in very hard spherical or cylindrical containers at the pressure of 20-25 mpa.

Usage

  • CNG is used in combustion engines which are modified or manufactured for CNG use. It's generally used in Buses altogether over the world.
  • In India, it's used in Buses also as in three-wheeler Autos.
  • Its use as a vehicle fuel was introduced late in the eighteenth century and the first gas Vehicle (NGV) was patented within the U.S.
