Compressed Natural Gas (CNG) is an eco-friendly, clean-burning alternative to petrol and diesel. It is a non-toxic mixture of hydrocarbons, consisting primarily of methane.
HCGD(B)L operates CNG stations in Bhiwadi to supply clean fuel to the transport sector, including cars, buses, and other commercial vehicles.
CNG offers significant advantages over traditional petrol and diesel for vehicle owners and the environment.
CNG is a convenient and environment friendly fuel.
CNG is a clean and green fuel that reduces harmful emissions due to the absence of lead and benzene.
CNG does not contaminate or dilute the crankcase oil.
Being gaseous, it mixes in air easily and evenly for efficient combustion.
It is less likely to auto-ignite on a hot surface due to its narrow combustibility range (5–15% in air).
It has a low operational cost — almost half the price of petrol or diesel.
It reduces carbon monoxide emission for cleaner air.
CNG kits can be installed in all four wheelers and most commercial vehicles.
A standard CNG kit includes the following components for safe and efficient operation in your vehicle.
Follow these essential safety precautions while using CNG in your vehicle.
In case of any leakage in the fuel system, the vehicle should be kept sufficiently away (more than 5 mtr) from any ignition source.
Always use a good quality CNG cylinder from an authorized manufacturer and get it hydro tested as per safety regulations.
The CNG kit installed in the vehicle should be insured along with the vehicle accessories.
Pollution checks and a valid pollution certificate are mandatory even after converting the vehicle to CNG, as per Govt. guidelines.
A comparison of key properties of CNG against Petrol, Diesel and LPG.
| Property | Unit | Petrol | Diesel | CNG |
|---|---|---|---|---|
| Relative Density (Water = 1) | — | 0.74 | 0.84 | — |
| Relative Density (Air = 1) | — | — | — | 0.64 |
| Auto-ignition Temperature | °C | 360 | 280 | 540 |
| Flammability Range | % in Air | 1–8 | 0.6–5.5 | 5–15 |
| Flame Temperature | °C | 2,030 | 1,780 | 1,900 |
| Octane Number | — | 87 | — | 127 |
Higher auto-ignition temperature and octane number make CNG a safer, knock-resistant fuel.
