The FEV Group with headquarters in Aachen, Germany, is an internationally recognized development service provider for drive and vehicle technologies. The company offers its global transport industry customers a complete range of engineering services, providing support in the design, analysis and prototyping for powertrain and transmission development, as well as vehicle integration, calibration and homologation for advanced internal combustion gasoline-, diesel-, and alternative-fuelled powertrains. FEV’s competencies also include design, development and prototyping of innovative vehicle concepts, powertrain electronic control systems and hybrid-electric engine concepts that address future emission and fuel economy standards. In recent years, FEV has started the development of water injection assisted combustion mode because for some vehicles we see the possibility to increase engine power and efficiency compared to state-of-the-art engine without this technology. Now, we would like to further optimize the technology by developing an engine with direct water injection and we would like to make this technology more user-friendly by generating the water for this technology directly from the exhaust gas, thereby avoiding the customer to filling up water as an additional working fluid.
