Natural-gas Vehicle Design——Fuel Storage

The majority of NGVs operate using compacted natural gas so the fuel occupies less space. At a encouraging station, gas is squeezed to 3, 000-3, 600 lbs per square inch prior to being pumped into high-pressure, tube-shaped cylinders that are attached with the rear, top or undercarriage of the vehicle. The storage space tanks of early NGVs were bulky and used much of the vehicle's cargo area, but newer, more light-weight cylinders have been developed. Known as Integrated Storage Systems (ISSs), these all-composite cylinders tend to be contained within a fiberglass covering and impact-absorbing foam to safeguard them in the event of a crash. The actual cylinders also have a smaller size so that three of them could be housed together in a shape and size resembling a conventional gasoline container.
