System with fuel

The system with fuel is intended to receive, store and deliver the Carburant of a vehicle Automobile in liquid or gas form.

Composition

The system with fuel is generally consisted of the following elements:

stopper and pipe of filling;
tank with fuel;
management system of the vapors;
petrol station, filters and measures;
feeder engine.

The system also integrates according to the standards in force of the systems of depollution: the canister with activated carbon for the vehicles with gasoline as well as a system of proportioning of additive, for vehicles with diesel motorization, being able to be used in particular as catalyst with the combustion of soots in the filter with particles.

The great majority of the fuel tanks store gasoline S or Gasoil S in liquid form; they are made out of plastic (Polyéthylène high density the full-course for gas oil tanks, fluorinated or multi-layer (polyethylene, adhesive, barrier, adhesive, polyethylene) for the gasoline tanks.

Regulations

The system with fuel is strongly regulated, in the majority of the countries, that is on the level of the mechanical resistance, the evaporative emissions, electrostatic discharges or of recycling.

Innovations

The system with fuel is the subject of regular innovations. Like, for example:

the manufacture of systems to quasi-null emissions emission, answering the most severe regulations (Californian, called PZEV - Partial Zero Emission Vehicles -);
the development of heads of filling without stopper (head with integrated obturation);
the integration of a system of proportioning of additive of very high degree of accuracy (5 ml).

Advantages of the plastic tanks

The tank out of plastic replaced large scales with the metal tanks for the following reasons:

Satisfaction of the user

The flexibility of the technique of manufacture of the plastic tanks make it possible to carry out very complex forms using all spaces available under the vehicle by maximizing the autonomy of the vehicle. Moreover, thanks to the use of the plastics, corrosion, internal and external, is absent.

Environmental assessment

Polyethylene is completely which can be recycled, as well by mechanical way as thermal. The studies of éco-assessments showed the superiority of the plastic systems in analyzes of the " puit with the roue" (" well to wheel ") who integrates the whole of the chain, since the extraction of oil until the end-of-life of the véhicule.
The profit of weight of the plastic systems contributes to the reduction of consumption while carburizing and thus to the production of CO₂. The bio-fuels do not present a chemical compatibility issue or of corrosion.

Safety

Polyethylene can undergo very important lengthenings (several tens of %) in the event of impact without rupture, which confers on the tank higher properties in term of resistance to the crash landing. In the same way, its low thermal conductibility reduced the transfer of heat and thus of vaporization and setting under pressure of the tank in the event of fire under the vehicle.
