What is CNG: Introduction about CNG?

Natural gas comprises mostly of methane (CH). In addition to this, it generally contains ethane, propane and butane, long-chain hydrocarbons, water, hydrogen sulphide (H S) as well as motionless gases such as carbon dioxide (CO) and nitrogen (N). The composition, though, depends to a huge amount on the deposit. Natural gas is compressed to 00 bars and hold as CNG (Compressed Natural Gas) in stress container on the vehicle. The gas is generally depressurized to 7 bars by a high-pressure regulator and supplied to the engine stimulation system through a particular mixing device and mechanism. In contrast with gasoline, natural gas has critical volumetric energy substance. For that reason, natural gas can only virtually and practically be applied in convey after being processed to a fuel with advanced volumetric power substance.

Environmental View:

 

It will take less time that, the earth used to be liberated of toxic compounds in the atmosphere, nothing like today when each person is contributing a huge quantity of waste gasses in the air. These waste gasses exit through the vehicle’s exhaust pipe and into the atmosphere, free, free to pollute the world.

The subject matter for discussion is that which fuel contributes more, CNG Compressed Natural Gas OR Normal Pump Gasoline.
In speculation, CNG is theoretical to be a lesser amount of harmful for the
environment. Carbon monoxide and non-methane hydrocarbons are reduced by up to 90 % in contrast with gasoline (on a car without a catalytic converter). The method catalytic converter designed for gasoline remains chiefly ineffective for the degradation of nitrogen oxides and methane in natural gas procedure primarily because of low carbon monoxide values.

Though, the superiority and quality of CNG in our country has led many to consider that it is not the clean fuel as it should be. Local CNG suppliers use low quality mixtures, introduce toxins into the gas stream to save up money and raise capacity. Even after looking at these features, CNG is method cleaner in an interior combustion engine than Gasoline. It creates pollution and produce global warming.

Merits of CNG over Gasoline:

  • 20- 25 % less carbon dioxide release.
  • Up to 90% less carbon monoxide emission.
  • 75-90% less non-methane hydrocarbons.
  • Approximately 80% less ozone worsening prospective.
  • No Acid Smell from the exhaust gasses.
  • No capacity losses through vaporization from the tank while refilling.
  • No carcinogenic materials.
  • Less costly than gasoline.

 

Demerits of CNG over Gasoline:

  • Intense methane gas emission.
  • About 50 – 100 % more nitrogen dioxide emission.
  • 20- 30% less power production with existing double fuel engines at optimized conditions.
  • Additional fuel station network essential rising Fire Risk.
  • Weight and Space requirements for gas cylinders in a vehicle.
  • Frequent Fill-ups.
  • Perilous Fire risk in case of Accident.
  • Dangerous outburst exposure in case of Accident.
  • Fire Hazard in case of gas trickle &/or substandard cylinders.
  • Low Reliability.
