Obtained from porous rocks, limestones or underground sandstones, normally associated with oil, natural gas is an energy source found in the gaseous state. The natural gas used in automotive vehicles (CNG) is a product basically formed by light hydrocarbons, mainly methane and ethane.
Vehicle natural gas emerges as an effective alternative to reduce dependence on oil, in addition to being a less aggressive source for the environment. The use of this fuel reduces by 65% the emission of polluting gases (especially carbon dioxide) responsible for intensifying the greenhouse effect.
Another positive aspect of CNG is in relation to financial savings, as its cost is lower than that of gasoline and alcohol, in addition to having a higher yield: a cubic meter of CNG is enough for a car to travel 13 kilometers, while an alcohol car travels approximately 7 kilometers with a liter of fuel. fuel.
To receive vehicular natural gas, the car must be adapted. It is essential that this conversion takes place in authorized and specialized locations, thus ensuring security. The value of this procedure is not cheap, however, the return is quick, since CNG is much more profitable compared to other fuels.
CNG must be stored in a cylinder suitable for receiving such fuel. In order to ensure consumer safety, this cylinder is subjected to a treatment process called tempera, in which it is heated to high temperatures and receives some substances to strengthen its resistance.
Vehicle natural gas is considered an extremely effective fuel in the search for less aggressive alternatives to nature. Among the positive aspects are: it is non-toxic, its value is lower than that of gasoline and alcohol, has no impurities, emits less pollutants, etc.
