Compressed Natural Gas (CNG) is a substitute for gasoline (petrol) or diesel fuel. It is considered to be an environmentally "clean" alternative to those fuels. It is made by compressing methane (CH4) extracted from natural gas. It is stored and distributed in hard containers, usually cylinders.

Green fuel -
Commonly referred to as the green fuel because of its lead and sulphur free character, CNG reduces harmful emissions. Being non-corrosive, it enhances the longevity of spark plugs. Due to the absence of any lead or benzene content in CNG, the lead fouling of spark plugs, and lead or benzene pollution are eliminated.

Increased life of oils -
Another practical advantage observed is the increased life of lubricating oils, as CNG does not contaminate and dilute the crankcase oil.

Mixes evenly in air -
Being a gaseous fuel CNG mixes in the air easily and evenly.

Petrol and diesel vehicles pollute envirement by releasing harmfull gases like Nitrus Oxide, Carbon Monoxide, Carbon Dioxide and Hydro Carbons. These gases are responsible for thousands of premature deaths around the world and effect other living things. Majority of people convert their cars to CNG for financial reasons, it is worth remembering that you are also giving your contribution towards working for a clean & Green Environment. CNG converted cars have lower Nitrus Oxide, Carbon Monoxide, Carbon Dioxide and Hydro Carbons, which are the four major pollutants in exhaust fumes. Even if the environmental side of CNG is not what makes you convert your car, it is a great sweetener when you see the little CNG light on your dashboard go green that you know you are doing the same, and saving a fortune.

Q.1) What is CNG?
Ans. CNG stands for compressed natural gas. It is gaseous fuel and is a mixture of hydrocarbons mainly Methane. For use in Automobiles as fuel, it is compressed to a pressure of 200-250 Kg/cm2 to enhance the vehicle on-board storage capacity.

Q.2. Is CNG safe?
Ans. Yes, it is safe. The properties of CNG make it a safe fuel. It is lighter than air, so in case of a leak it just rises up and disperses into the atmosphere. Besides, a high auto-ignition temperature of 540 degrees centigrade as against petrol’s 360 degrees centigrade, makes it a safe fuel. Also, in case of a leak, if CNG’s concentration in the air is less than 5% and more than 15%, the gas will not burn even in the presence of a spark.

Q. 3. What is involved in converting a vehicle to a CNG-friendly one?
Ans. All spark-ignited engines can be converted to CNG, but a specially designed conversion kit is required for the purpose. The kit consists of a cylinder to be fixed in the boot of the car and other equipment to allow gas flow into the engine.

Q. 4. Can a car, fitted with CNG conversion kit, run on Petrol after its CNG gets
over?
Ans. Yes, after conversion to CNG the vehicle can run on petrol whenever desired simply by flicking a switch on the dashboard.

Q. 5. What is the cost of converting a vehicle to a CNG-friendly one?
Ans. The cost of converting a vehicle to CNG depends on its type and make. For further details Click Here

Q. 6. What are the dimensions and weight of a CNG cylinder?
Ans. CNG cylinders are manufactured from a special steel alloy and are seamless in construction. Their compact size allows them to easily fit even in a small car. An empty CNG cylinder with a 50 litre-water-carrying capacity weighs 48 kg, with a length of 835 mm and a diameter of 316 mm. The 50 litre capacity cylinder is the one most regularly used; cylinders with 45 litre, 55 litre, 60 litre and 65 litre capacity are used as well.

Q. 7. What is the capacity of a cylinder, and mileage from one fill? How does one
get to know the quantity of CNG left in the cylinder?
Ans. Under city road conditions and may vary from vehicle to vehicle and driving habits.

Q. 8. What is the pressure of CNG in a cylinder? Is refuelling of a cylinder safe,
given the pressure?
Ans. CNG cylinders are designed and built in such a way so as to withstand high pressure. The maximum pressure in a CNG cylinder is up to 200 kg/cm2 (g) (about 2840 pounds per square inch (gauge) or psi[g]). CNG cylinders are safe as they are manufactured as per specific requirements and tested before use, in accordance with international specifications and standards and they are duly approved by Chief Controller of Explosives. Moreover, these have been provided with a \'safety burst disc\' such that in case of inadvertent high-pressure/high temperature at the time of filling or at any other time, this disc is ruptured and pressure released.

Q. 9. How much will be the saving after conversion to CNG?
Ans. The fuel bill on the basis of average running of vehicle is reduced by 50 percent approximately after conversion of CNG at the present price of CNG & Petrol in Delhi.

Q. 10. Does CNG kit require servicing?
Ans. CNG kit is safe and simple. It gives years of trouble free operation. It doesn’t require frequent servicing. Just as for all other fuels, it is advised to have routine services. An authorized person should be consulted for service. As per Gas Cylinder Rules, 1981, the cylinder should under go hydro-stretch testing every 5 years to check pressure tolerance.

This valve is control the filling of CNG Fuel into the Cylinder of CNG Automobiles.

This regulator help in regulating the amount of gas inflow to the cylinder.

Mixer in the CNG Kit enables gas and air mixer before entering onto the cylinder of the automobile.

Pressure Guage is the meter that measure the pressure of the gas inside the cylinder at any time. This is one of the important part of CNG kit.

High Pressure Pipe is the pipe in the cng kit that is require to connet between cylinder and cng kit. It is made of higly durable plastic material so that it can load high pressure on it.

Venting Bag allows to absorb air from the environment and supplies to gas air mixer chamber.

CNG Cylinder id the container that contain CNG gas at high pressure for the fuling to the engine of automobile. It is made of higly durable metal and tested before the filling the gas into it.

Cylinder\'s Support System are the basic accessories that bind and hold the CNG Cylinder into the automobile. They also keep CNG Cylinder proper aligned so that to mentain proper pressure.
