An all natural gas vehicle is an alternative fuel automobile that uses compressed gas (CNG) or liquefied gas (LNG) as a cleaner alternative to other fossil energizes. Natural gas vehicles must not be confused with automobiles powered by gas, which is a fuel having a fundamentally different structure. Worldwide, there had been 14. 8 million gas vehicles by 2011, brought by Iran together with 2.86 trillion, Pakistan (2.85 million), Argentina (2.07 million), Brazil (1.70 million), and Asia (1.10 million).
