Low Emissions

Since the 80’s and the growing concerns about air quality in a booming automotive market, new regulations have boosted innovation in fuel system construction. From the monolayer HDPE construction that emerged in the 70’s, Fuel Systems Researchers have first introduced a surface barrier treatment obtained by an exposure to fluorine during the manufacturing of the tank, creating a kind of Teflon™ layer on the surface. In the 90’s, 6-layer coextrusion technology was developed to further reduce the tank permeability, whatever the fuel is.   

At the turn of the millennium, the focus was shifted towards system emissions, and allowed Researchers to develop new technologies allowing to integrate a certain number of active components within the tank, while using novel materials, components and constructions for the external ones.

The achieved level allows plastic fuel systems to pass toughest regulations and to minimize the contribution to overall car emissions. 

Today, the focus is mainly related to exhaust emissions, for which the Fuel Systems industry did develop innovative SCR system solutions, allowing to store and distribute on-board urea-water solutions, which has been recognized as the best technique to abate engine NOX emissions.
