Most of today we are preffering to out by using vehicles either on Car or by two-wheeler.In previous year most of the vehicles were using petrol as fuel resource to their vehicles and trucks and heavy loaded vehicles were using desiel as fuel option. But as the technology improved and new fuel which energy saving and less pollution free resource is CNG.Natural gas, a fossil fuel comprised mostly of methane, is one of the cleanest burning alternative fuels. It can be used in the form of compressed natural gas (CNG) or liquefied natural gas (LNG) to fuel cars and trucks.
Dedicated natural gas vehicles are designed to run on natural gas only, whiledual-fuel or bi-fuel vehicles can also run on gasoline or diesel. Dual-fuel vehicles allow users to take advantage of the wide-spread availability of gasoline or diesel but use a cleaner, more economical alternative when natural gas is available. Since natural gas is stored in high-pressure fuel tanks, dual-fuel vehicles require two separate fueling systems, which take up passenger/cargo space.
