Natural gas (CH4), or methane, is the ecological fuel par excellence, a resource readily available in nature that is not obtained through a refining process but is immediately ready for use as ecological fuel.
Natural gas does not contain impurities, sulphur, lead compounds or aromatic hydrocarbons, meaning that its exhaust fumes emit less pollutants and are free of odour, particulate matter and combustion residues; in addition, its use leads to a production of CO2 much lower than that of other fuels, thus reducing the negative effects of propulsion on the ozone layer and on the atmosphere.
Another great advantage for the environment derives from the distribution of methane, which compared to other fuels has a much lower cost. Thanks to the underground network of methane pipes, this fuel does not require road transportation and does not increase traffic. One kg of methane corresponds to circa 1.6 litres of petrol, and filling up a medium-powered car with methane today only costs about 11 euros. In addition, methane adds an elevated antiknock value to its other great qualities as a fuel.
The acronym LPG stands for Liquefied Petroleum Gas; this is a by-product of the refinement of raw petroleum and is found in nature in gaseous form. It passes to the liquid state when it is exposed to pressures above the atmospheric pressure and/or to low temperatures.
The LPG used as fuel is a mixture of propane and butane gas, which ensures a good performance of the car in terms of power, flexibility and engine function.
Its combustion produces less carbon oxides, nitrogen oxides and unburned hydrocarbons than that of petrol and diesel, while it does not contain aromatic hydrocarbons or highly polluting substances such as sulphur dioxide and particulate matter. Unlike some years ago, today’s LPG systems make it possible to maintain the same automotive performance as with petrol, but at a lower cost per kilometre.
Heart and passion, present and future.
The prediction of a progressive extinction of traditional energy sources has led to the research for alternative energy sources. As it has always done in its 40 years of activity, Bigas International Autogas Systems looks toward the future for innovative solutions.
Hydrogen: the energy of the future
Hydrogen is the big chance for a zero emission future. The new Bigas methane Reducer RI 27 has been already engineered to meet this new challenge.
