CNG (Compressed Natural Gas)
CNG is compressed natural gas used as a car fuel.
What is CNG (Compressed Natural Gas)?
It is mainly methane. It is stored in high-pressure tanks. Biomethane can also be used. CNG cars usually have a small petrol tank as a backup and start or run on petrol when gas runs out. Natural gas burns cleanly with low particulate emissions. Gas tanks have a limited service life and must be inspected or replaced according to national rules, so check the tank dates when buying a used CNG car.
How it works
The gas is injected and burned in the engine.
Why it matters for your car
Tanks must be inspected regularly. Refuelling networks vary by country.
