On refuse collection and recycling missions it is estimated that the saving can be up to 20,000 Euros per year. In fact for regional distribution missions it has been estimated that savings of up to 10,000 Euros are possible compared with a traditional Diesel-powered vehicle, over a distance of approximately 40,000 km per year. Furthermore, the use of natural gas-powered vehicles, whether CNG or LNG, represents a considerable economic asset for customers. In addition to the considerable advantages in terms of reduced emissions, which the CNG technology already guarantees, the LNG system also enables a reduction in terms of unladen weight and an increase in useful load.
In LNG vehicles the natural liquified gas is stored in liquid form at -125✬, in cryogenic tanks, and is fed to the engine as natural gas in gaseous form, after been heated in a heat exchanger. In vehicles using CNG technology (Compressed Natural Gas), the methane is stocked in gas form in steel tanks at a pressure of 200 bars. The main feature on the Iveco stand in Amsterdam is the new Stralis LNG.
