What is a natural gas vehicle?
A natural gas vehicle is a car, truck, van or bus that uses compressed natural gas (CNG) to fuel its engine. CNG is a gaseous fuel, not a liquid fuel, and so is compressed at 3,000 to 3,600 pounds per square inch (psi) and stored onboard a vehicle in steel, aluminum, fiberglass or carbon-fiber cylinders.
