Vehicle natural gas because of its prominent effect of energy-saving emission reduction and oil-gas price ratio, much attention of all countries in the world. Compared with gasoline vehicles, gas vehicles can reduce emissions of 90% of carbon monoxide, 72% of hydrocarbon emissions, emission reduction of nitrogen oxides 39%; per hundred kilometers to compare the cost of fuel consumption, automotive gas and gasoline prices Ratio is 0.6 ~ 0.75 1.
