Natural gas, a fine alternative energy, is an important and clean fuel that may be able to address the environmental issues caused by automobiles.
It is not only friendly to the environment, but demonstrates excellent performance and reliability.
Liquefied natural gas (LNG) is purified natural gas containing more than 90 % methane and cooled down to -164 to -161C. In this state it is odourless, colourless, only slightly toxic and non-corrosive. It is more than 600 times more compact than in its gaseous state and weighs half as much as water.
A gas generator is a device for generating gas. It may take many forms but often refers to a device, similar to a solid rocket or a liquid rocket that burns fuel to produce large volumes of relatively cool gas, instead of maximizing the temperature and specific impulse.
