What is a natural gas vehicle?
A. A natural gas vehicle (NGV) is a car, truck, van or bus which uses compressed natural gas to fuel its engine. Because it is not a liquid fuel, natural gas is compressed at 3,000 or 3,600 pounds per square inch so that it can be stored in steel, aluminum, fiberglass or carbon-fiber cylinders. Q. How do NGVs work? A.NGVs work like conventional liquid gasoline or diesel-powered vehicles in that they burn a gaseous mixture of fuel and air in an engine; however, natural gas has the distinct advantage of already being a gas, which helps the engine run cleaner. Q. How are NGVs refueled? A. At fueling locations, natural gas is compressed and dispensed into vehicles in much the same way as gasoline. Fleet fueling stations can be conveniently located on-site, using either the “quick-fill” or “time-fill” method of fueling. Quick-fill refueling takes about three to seven minutes. Time-fill refueling is usually done overnight, in about five to eight hours. A refueling station may be installed wh
Natural gas vehicles (NGVs) are created to run only on natural gas. NGVs have two different fueling systems that enable the vehicle to use either natural gas or a conventional fuel (gasoline or diesel).Natural gas vehicles are fueled with compressed natural gas (CNG) or liquefied natural gas (LNG) and there are many CNG Stations are available throughout the country. If you compare vehicles fueled with conventional diesel and gasoline, NGVs can produce low amounts of harmful emissions, so we can say that these are Eco-friendly and chep too.
A natural gas vehicle is one that runs on natural gas instead of gasoline or diesel fuel. Is using natural gas in engines a new idea? Not at all. The first natural gas engine was built in 1860, before the development of the gasoline engine. Natural gas vehicles have been used with much success in the United States since the 1960s and in Europe for nearly 50 years. In fact, there are currently more than 30,000 natural gas vehicles on U.S. roads and over 700,000 worldwide. How do vehicles run on natural gas? Natural gas used by these vehicles is compressed to about 3,500 pounds per square inch and is stored in cylinders mounted on the vehicle. When natural gas is required by the engine, it is released from the cylinders and passes into a pressure regulator that brings it almost to atmospheric pressure. Then it goes into an air-mixer, where it is combined with air in the precise air-to-gas ratio required for ignition. Lastly, the natural gas flows into the engine’s intake air stream for c
