JetPro Europe AG offers the JetPro Diesel Booster, a device for thermal and physical pre-treatment of diesel fuel intended to improve fuel efficiency and emissions performance. The website explains the system expands and preheats fuel and passes it through a reactor that enriches the fuel with metallic ions, which the company says leads to more uniform combustion, reduced soot and NOx and fuel savings of around 10–15%. The site also refers to DEKRA certification and accompanying test reports and functional evidence for the products.
