Answer 2

ADVANTAGES OF CNG:

1. ADVANTAGES OF CNG:Natural gas is significantly less expensive than gasoline. The cost of natural gas can go as low as $0.64
2. CNG is more eco-friendly. Natural gas produces far fewer harmful emissions and hydrocarbons.
3. Using CNG makes the engine cleaner and more efficient. CNG minimizes harmful carbon deposits when combusted. This results to a cleaner and more efficient engine as well as longer lasting spark plugs.
4. CNG has higher Octane levels averaging over 120 Octane .

ADVANTAGES OF PNG:

1. PNG is one of the cleanest burning fuels. The combustion of PNG gas releases very small amount of SOx, NOx, virtually no ash or particulate matter and lower levels of carbon dioxide, carbon monoxide and other reactive hydrocarbons.
2. No scaling or sooting takes place in use of PNG gas and hence reduces maintenance cost as compared to other fuels.
3. The combustible mixture of PNG gas and air does not ignite if the mixture is leaner than 5% and richer than 15% of the air-fuel ratio required for ignition. PNG gas is lighter than air. Therefore, in case of a leakage, it just rises and disperses into thin air.
4. PNG is generally cheaper than liquid & gaseous fuels like FO, LDO, CBFS, Diesel, and LPG.
