What is the Full Form of CNG? | Compressed Natural Gas

Full Form of CNG

The Full form of CNG is Compressed Natural Gas. Diesel, petrol, and LPG can all be substituted with compressed natural gas (CNG). Compared to the other fuels mentioned above, CNG burns cleaner and creates fewer hazardous emissions. Compared to other liquids, natural gas poses less of a concern in the event of a leak because it is lighter than air and scatters quickly after being discharged.

The CNG’s History

  • The usage of natural gas as a vehicle fuel was first introduced in the late 1800s model.
  • After the Second World War, many European countries, including Italy, adopted compressed natural gas (CNG) as their main engine fuel. 
  • The first natural gas engine was produced in the United States.
  • Oil reservoirs utilize CNG. Additionally, landfills and sewage treatment facilities may contain it.
  • Natural gas is compressed to reduce the pressure to less than 1% of the normal atmospheric pressure. 
  • It is spread in robust cylinder- and sphere-shaped tanks and maintained at a pressure of 20–25 MPa.

Features of CNG

  • CNG is a substance without smell, color, or flavor, and it has no poisonous or corrosive qualities.
  • The main application is as a petrol alternative in cars.
  • The primary component of CNG is methane.
  • Typically, it doesn’t produce many greenhouse emissions.
  • It is quite healthy given how easily it spreads into the air.
  • The primary sources of CNG include oil wells, natural gas, coal, bed methane, and coal.

Benefits of CNG

  • It is less expensive than the diesel and petrol used to power buses and other vehicles.
  • The cost of maintaining CNG-powered vehicles is minimal, especially when compared to those powered by diesel and petrol.
  • Because it emits fewer harmful and unneeded emissions than other options, including petrol and diesel, it is more environmentally friendly.
  • The crankcase oil extends the life of lubricating oil because it doesn’t actually dilute and pollute.
  • It needs a high temperature of 540oC or even more with autoignition.
