Ans. CNG is Compressed Natural Gas, having the same properties as that of Natural Gas. The Auto ignition temperature of Natural Gas is 540 degrees Centigrade, which is far greater than its substitutes. The Lower Explosive limit and Higher explosive limits of 5% and 15% respectively are is also substantially higher than Petrol, Diesel and Auto LPG. Due to lower density of Natural Gas, it is lighter than Air and hence in case of leakage it quickly disperses in to Air. All these characteristics make Natural Gas a safe fuel compare to other alternative fuels available today.
Ans. CNG conversion is suitable for all petrol vehicles with carburettor, turbo, injection, and catalytic engines. CNG conversion is also possible for the most common direct injection engines.
Ans. CNG is the cleanest, greenest and most economical fuels available today. CNG combustion does not produce carbon residues (which cause engine oil to turn black). For this reason, the engine oil in gas vehicles remains clear and its properties unaltered, even after many thousands of kilometres and this helps to improve performance and reduce engine wear and tear.
Ans. Yes, using petrol as well as CNG is possible. INfact today some car manufacturers have already launched models where this feature is factory fitted. After installation of the CNG system, the petrol vehicle becomes Bi-fuel, in other words, it can run either on CNG or petrol. In this way the original economy of the vehicle actually increases, depending on the size of the gas tank installed.
Ans. CNG tanks are made from extremely resistant full steel to hold the final weight of the cylinder. They have extremely high mechanical resistance, tested to 300 bars, 1.4 times the normal working pressure, and are therefore extremely safe, approved and tested according to extremely stringent standards.
Ans. Using methane as a fuel reduces the emission of the greenhouse gas CO2 by over 20%. Emissions of CO and Nitrogen Oxides (NOx) are also significantly lower. HC emissions are also almost totally made up of pure, non-toxic methane. Gas cars do not produce particulate, in particular the PM10 that are critical for urban pollution.
Ans. In general, CNG cylinders suitable for 4 wheelers have storage capacity of 9-10 Kg of CNG. Ideally a CNG car can run around 180-230 Kms with 9-10 Kg of CNG.
Ans. Yes, a diesel vehicle can be converted to run on CNG, but the conversion cost is higher than the conversion of petrol vehicles.
Ans. CNG is the fuel that is considered as least polluting. As the Global warming is increasing at tremendous rate, adaption of CNG can bring that rate down and help us in creating Environment with less pollution.
