CNG stands for Compressed Natural Gas. It is a gaseous fuel and is a mixture of hydrocarbons, mainly methane, in the range of 89% to 90%.
Yes. CNG is lighter than air and disperses quickly if leaked. It has a high auto-ignition temperature of 540°C (versus petrol’s 360°C), and it will not burn if its concentration in air is below 5% or above 15%.
A specially designed conversion kit is required, consisting of a cylinder for the car boot and equipment that allows a controlled flow of gas into the engine.
Yes. Vehicles retain their petrol carburetor and fuel tank, enabling dual-fuel operation. You can switch between petrol and CNG using a dashboard switch.
CNG vehicles start easily with reliable idling and smooth acceleration. Acceleration may be slightly slower due to a 5–15% power loss, which can be minimized through proper tuning.
Yes, though the conversion cost is higher than for petrol vehicles.
CNG reduces air pollution, improves the trade balance as an import substitute, and creates business and employment opportunities — all at competitive pricing.
PNG FAQs
Natural Gas is primarily methane (CH4) with a small percentage of other higher hydrocarbons, making it a clean and versatile fuel.
Natural gas is continuously supplied through pipelines rather than stored centrally, making it safer than cylinder-based LPG.
Yes. PNG offers a continuous supply through pipelines, unlike LPG’s fixed-capacity cylinders that need periodic replacement.
Yes. An un-interrupted supply at a constant pressure is assured through the pipeline network with safety controls in place.
No. LPG appliances can be converted to PNG with minor modifications, since both fuels work in a similar manner.
Costs depend on the property type. A refundable, interest-free security deposit is required at the time of registration.
Billing is based on meter readings taken every two months for domestic consumers and daily for commercial customers. Bills are payable online or offline.
A 24/7 helpline service is available, with network control rooms staffed by engineers and technicians. Reach us via the emergency number or WhatsApp.
PNG has a narrow 5–15% inflammability range, is lighter than air (so it disperses if leaked), is installed at low pressure, and has isolation valves — unlike heavier LPG.
