CNG - Advantages
CNG has several distinctions over other fuels:
  • Environmental
    • No impurities, No Sulphur (S), No lead (Pb)
    • Very low levels of polluting gaseous emissions without smell and dust
    • Molecular structure compactness prevents the reactive processes which lead to the formation of Ozone (O3) in the troposphere.
  • Safety
    • Lighter than air - in case of leak no dangerous puddles
    • Unlikely to ignite due to:
      • High ignition temperature
      • Narrow range of ignition
    • Lowest injury and death rate per vehicle mile
    • CNG cylinders structurally most sound and have passed every severe tests
  • Economical
    • Cheaper than conventional fuel.
    • Pay back period is short
  • Technical
    • Very high antiknock power (more than 120 ON) allows greater performance compared to petrol one.
    • Does not require refining plant or additive adding and can be used immediately after its extraction.
    • It has no evaporation leaks and spills of fuel, both during refueling and feeding of the car.
    • Its combustion produces a very low quantity of carbon deposits (permits a longer life of lubricant oil, spark plug, piston drum, valves & other components)
