Q8 fuels

Petrol

Unleaded petrol

This is a fuel made up of a mixture of hydrocarbons produced in refineries using different techniques (distillation, isomerisation, alkylation, reforming, cracking). It is designed for internal combustion engines with spark ignition, namely internal combustion engines.

Unleaded premium petrol (Eurograde 95) meets the requirements of the European EN 228 standard and is used in vehicles equipped with a catalytic converter. The combination of catalytic silencer and unleaded petrol has enabled the lowering of emissions of regulated pollutants (NOx, CO, HC) by more than 80%. Grade 95 indicates a 95 octane RON (Research Octane Number) petrol.

Diesel

This is divided into two forms: diesel motor fuel and heating oil.
Both are mixtures of hydrocarbons produced in the refinery using different techniques (distillation, cracking, visbreaking). The specifications of the diesel motor fuel are established by the European EN 590 standard while those of the heating oil are fixed by national regulation UNI 6579.

Diesel motor fuel

This is a product used to power compression-ignition engines, both in large and slow engines in vehicles used for transporting goods or in marine use and in small and fast engines fitted in cars.
The formulation of diesel allows the use of these engines in the most varied temperature and running conditions: it assures good operation at low temperatures, does not give rise to paraffin deposition in the tank and filters, has good ignition, limited smokiness and emission of pollutants.

Heating oil

This oil is destined for combustion in central heating boilers. The type of application means that the characteristics (and relative limits) that define its suitability for use in this sector may be different to those of diesel motor fuel.

LPG

Liquefied petroleum gas (LPG)

This is a mixture of light petroleum fractions (propane and butane), obtained in the refining process, which have the property of being gaseous at atmospheric pressure and ambient temperature but of becoming liquid under a light pressure.

LPG is used in combustion and carburation; the fact that is a gas at the time of use allows an excellent mixing with the air, with more efficient combustion, reduction of consumption and of emissions of polluting compounds.

The product used as fuel complies with the limits set by the European EN 589 standard.

Methane

A natural gas compressed to 220 bar, it is a less polluting fuel, usable for cars and trucks.

It is actually a mixture of gases mainly composed of methane, but also other light hydrocarbons, such as propane, butane and traces of other gases, which allows a cost saving of about 60% compared to petrol: the energy contained in 1 kg of methane allows one to travel 1.5 - 1.6 times further.

Of all fossil fuels, it boasts the highest ratio of energy output to the amount of carbon dioxide emitted, resulting in a reduced global warming effect.

Thanks to the extremely low pollutant emissions, natural gas vehicles are generally exempt from traffic restrictions and limitations.
