Tanks to the ease with which LPG passes from a gaseous state to a liquid one and vice versa, it can be stored and transported using containers at moderate pressures and can be used by means of simple, low cost appliances...
Italy’s nationwide LPG sale and distribution network comprises some 2000 stations that satisfy the demand of approximately 1,200,000 consumers. LPG has a higher calorific value than conventional hydrocarbons and its perfect blendability with air makes it possible to burn weaker blends with higher energy efficiency. By virtue of LPG’s pureness characteristics, at the lower pressure values that the mechanical components are subject to and the absence of dilution of the lubricating oil, engines powered by LPG are less noisy and have a longer service life, with a substantial reduction in maintenance expenses.
LPG also has a higher number of octanes than petrol, which allows a greater compression ratio with higher engine efficacy. Together with natural gas, LPG is the cleanest of fossil fuels, which makes it compatible with a more pleasant environment. The use of LPG increases the efficacy and duration of catalytic exhaust pipes due to the absolute absence of pollutants able to damage the catalytic converter.
The use of LPG for transport requirements allows a substantial abatement of emissions, with positive effects on the quality of the environment, which has become particularly important following the 1997 Kyoto summit, on the release of greenhouse effect gases into the atmosphere. LPG-powered vehicles boast the following advantages over traditional fuels with regard to un-regulated pollutants:
- Emissions of polycyclic aromatic hydrocarbons IPA and aldehydes (formaldehyde, acetone, acrolein) far lower than diesel;
- Benzene, toluene and xylene emissions far lower than petrol
- Summer smog formation potential lower than petrol;
- Winter smog formation potential lower than diesel.
