What is Natural Gas?


Methane or natural gas is the utmost in environmentally friendly fuels: one of the most plentiful in nature.
In fact, Natural Gas does not contain any impurities, sulphur, lead compounds or aromatic hydrocarbons, resulting in extremely low levels of exhaust pollution without odour, particulate and combustion residue.
The chemical composition of Natural Gas causes much less production of CO2 compared to other fuels; it also reduces the formation of ozone in the atmosphere.

 

What’s the fuel distance of a vehicle that runs on Natural Gas?


The fuel distance of a car that runs on Natural Gas depends on the size of the tank or tanks installed when it is changed over.
Taking the example of a vehicle that does 10 km/l when running on gasoline, it should have a fuel distance of about 230 km with a 90 l tank, which is the equivalent of 23 l of gasoline, when running on Natural Gas.

 

Are Natural Gas tanks safe?

Tanks for Natural Gas are able to guarantee the highest levels of safety: in fact, they are all subjected to stringent testing, both at the time of homologation and during their working life.
The particular strength required to endure testing pressures of 300 bar and operating pressures of 220 bar means the cylinders are extremely resistant to impact.
The use of fully tested, extremely reliable components, the implementation of all methods during installation for the prevention of gas leaks, even in case of faulty operation, and the intrinsic properties of Natural Gas (high ignition temperature, ignition only possible inside a particular interval of mixing with air) are all factors that play an important role in favour of safety.
Natural Gas is lighter than air and so does not stagnate in case of leaks but is dispersed into the atmosphere without accumulating in the lower strata.
Opinions are also positive on an international scale.
Tests made by the most important institutes for safety throughout the world (Bureau Veritas in Norway, EPA in the United States, etc.) on Natural Gas bottles have always given results that are more than gratifying, showing the reliability of this type of tank is excellent.
A report by the Norwegian Bureau Veritas states that the risks connected with the use of vehicles powered by Natural Gas are no greater than the risks for vehicles that run on diesel.

What difference is there in performance compared to gasoline operation?

Modern LPG and Natural Gas power systems guarantee excellent engine performance and there is practically no change in how the vehicle drives.
The latest generation of LPG injection systems give rise to a difference of about 2% in terms of the vehicleÕs power when compared to gasoline, whilst a Natural Gas injection system gives rise to a difference of about 10/15 %.

 

What are the benefits of Natural Gas?

Firstly, there is the benefit in financial terms given the lower running costs of vehicles that run on Natural Gas compared to cars running on gasoline.
Natural Gas costs about 70% less than gasoline so it is possible to redeem the cost of the system quickly and then start saving money, even if the distances covered are not very high.
Secondly, there are the benefits for the environment as Natural Gas does not contain benzene or lead: the most harmful substances in other fuels, and particulate is not produced as a result of its combustion, one of the major causes of pollution in towns and cities.
Thanks to its environmentally friendly features, vehicles that run on Natural Gas can be used even when motor vehicle transport is restricted because of high levels of atmospheric pollution, if contemplated by local regulations.

 

Advantages of NGV 

– Longer service life to the exhaust system.
– Longer service life to spark plugs.
– Longer service life to oil and oil filter, as these are not affected by the pollutant
   agents produced by liquid fuels.
– The performance of one NGV m³ is 12% higher than that of one liter of gasoline
   because the heat rate is 12% higher than that of liquid fuels (95% methane).
– 100% safe, natural gas is lighter than the air we breathe, hence in the unlikely
   case of a leak, gas would rise and disappear causing no hazard.
