Compressed natural gas (CNG) is natural gas fuel that has been compressed to less than 1% of its volume at atmospheric pressure making naturally odorless, clear and non-corrosive. It can be used as a cheaper, greener, and more efficient alternative fuel to the traditional petrol and diesel fuels for vehicles.Diesel and gasoline vehicles will need to be converted to use CNG fuel.
CNG is comprised mostly of methane gas which, like gasoline, produces engine power when mixed with air and fed into engine’s combustion chamber.
Benefits of CNG
CNG is cheaper
CNG is almost one third the price of super gasoline, resulting in substantial savings in fuel costs.
CNG reduces maintenance cost
CNG contains no additives and burns cleanly leaving no by-products of combustion. The combustion chamber parts function at peak output for longer periods before requiring service. The engine oil also remains clean which minimises engine wear and requires less frequent changes.
CNG is more environment friendly
CNG engines run more quietly due to the higher octane rating of CNG over gasoline and they produce less exhaust emissions. Harmful emissions such as carbon monoxide (CO), carbon dioxide (CO2) and nitrous oxide (N2O) can be reduced by as much as 95% when compared to gasoline powered vehicles.
CNG is safer
CNG components are designed and made to international standards and are monitored to ensure safe operation. CNG fuel systems are also sealed, which prevents any spill or evaporation losses.
