COMPRESSED NATURAL GAS (CNG) TECHNOLOGY FOR POWERING VEHICLE

CNG is a safe fuel. Being lighter than air, it disperses easily into the atmosphere and does not form a sufficiently rich mixture for combustion to take place. CNG is 130 octane, which is considerably higher than 93 octane for petrol; consequently, CNG vehicle is more energy efficient. Higher octane rating allows higher compression ratios and improved thermal efficiency4, reducing carbon dioxide emissions. CNG allows the use of catalytic converter more efficiently than diesel. Compared to petrol or diesel, CNG vehicles emit 40% less of nitrous oxide (a toxic gas that creates smog), 90% less of hydrocarbons (which carry carcinogens), 80% less of carbon monoxide (a poisonous pollutant), and 25% less of carbon dioxide (a major greenhouse gas).
