1 FAQ-CNGWhat is CNG?CNG stands for Compressed Natural Gas. It is a gaseous fuel and is a mixture of hydrocarbons, mainly methane, inthe range of 89% to 90%. Due to its low density, it is compressed to a pressure of 200-250 Kg/cm (g) to enhance thevehicle on-board storage CNG safe?Yes, it is safe. The properties of CNG make it a safe fuel. It is lighter than air, and hence in case of leakage itdisperses into the atmosphere rapidly. Its high auto-ignition temperature of 540 degrees centigrade as againstpetrol s 360 degrees centigrade makes it even more safe fuel. Limited combustibility CNG s concentration in theair is less than 5% or more than 15%, the gas will not burn even in the presence of a spark adds further to its is involved in converting a vehicle to a CNG-friendly one?

2 All spark-ignited engines can be converted to CNG, but a specially designed conversion kit is required for thepurpose. The kit consists of a cylinder to be fixed in the boot of the car and other equipment to allow gas flow into a car, fitted with CNG conversion kit, run on petrol after its CNG gets over?Yes, even after conversion to CNG, the vehicle continues to be fitted with the petrol. The vehicle can therefore run ondual fuel, either onCNG or petrol, whenever desired, simply by flicking a switch on the is the cost of converting a vehicle to a CNG-friendly one?The cost of converting a vehicle to CNG depends on its type and make. As on, it roughly ranges between Rs 25,000to Rs 40,000 (approximately).What are the dimensions and weight of a CNG cylinder?

3 CNG cylinders are manufactured from a special steel alloy and are seamless in construction. Their compact sizeallows them to easily fit into a small car. An empty CNG cylinder with a 50 litre-water-carrying capacity weighs 48 kg(approximately), with a length of 835 mm and a diameter of 316 mm. The 50 litre capacity cylinder is the one mostregularly used; cylinders with 45 litre, 55 litre, 60 litre and 65 litre capacityare used as is the capacity of a cylinder, and mileage from one fill? How does one get to know the quantity of CNGleft in the cylinder?A cylinder with a 50 liter water-carrying capacity is capable of carrying approximately 9 kg of CNG. This is equivalentto liters of petrol and will allow a run of about 180-200 kms to a medium sized 1100 CC car.

4 An electronic fuelgauge fitted on the dashboard as part of the conversion kit indicates the quantity of CNG left in the is the pressure of CNG in a cylinder? Is refueling of a cylinder safe, given the pressure?CNG cylinders are designed and built in such a way so as to withstand high pressure. The maximum pressure in aCNG cylinder is up to 200 kg/cm2 (g) (about 2840 pounds per square inch (gauge) or psi[g] ). CNG cylinders are safeas they are manufactured as per specific requirements and tested before use, in accordance with internationalspecifications andstandards, and are duly approved by the Chief Controller of Explosives. Moreover, they are provided with a pressurerelief device (PRD) that consists of a fusible plug and a burst disc that ruptures in case of inadvertent high pressureand much will be the saving after conversion to CNG?

5 The fuel bill onthe basis of average running of vehicle is reduced up to 60 percent approximately. The cost ofinstallation of the kit is recovered within a year, given average distances covered in CNG kit require servicing?CNG kit is safe and gives years of trouble free operation. It doesn t require frequent servicing. Just as for allother fuels, it is advised to have routine services. An authorized person should be consulted for service. As per GasCylinder Rules, 1981, the cylinder should undergo hydro-stretch testing every 5 years to check pressure CNG have any harmful effect on the engine?Owing to CNG's distinct features, it does not contaminate or dilute crankcase oil, giving a new lease of life to theengine. The absence of any lead content in CNG helps avoid lead fouling of plugs, thereby enhancing plug life.

6 Oneof the important benefits of CNG is that upon entering the engine in the form of a gas (and not as a spray or mist likeother fuels), it doesn't disturb the presence of lubricating oil in the engine, and reduces chances of wear and have a Diesel engine-can it be converted, too?Converting Diesel cars is not as easy as converting Petrol cars. There is a simple reason for that. The mechanism ofDiesel cars is based on the principle of "self ignition". The combustion in Diesel engines is reached by mixing theDiesel fuel with hot air under a high pressure. Then, the fuel ignites automatically; an ignition spark is not required.(This is also the reason why a Diesel car should never be filled with ordinary Petrol). CNG, however, has a highignition temperature (about 0 C).

7 Diesel cars do not have sparks to initiate the combustion process. And the heatgenerated in a Diesel engine is not sufficient toignite the air-gas mixture. Hence, if a Diesel engine should beconverted to a CNG engine, holes have to be drilled into the engine block, and an additional spark plug system needsto be installed. This is very costly and requires much a CNGvehicle be driven outside Kanpur?CNG converted petrol car may be driven outside Kanpur as it is dual fuel car with the option of petrol. However, CNGpowered LCV/HCVs may not be driven outside Kanpur, as it is monofuel CNG environmentally friendlier than any other fuel?Yes, it is. As CNG mainly consists of methane, the exhaust fumes of CNG basically consist of water vapors, CarbonDioxide and some fractions of Carbon Monoxide.
