The FEV Group and automotive parts supplier, Hilite International, has agreed to collaborate in the development and manufacture of a two-stage, variable compression ratio (VCR) connecting rod.
The VCR technology meets challenges in downsizing and the associated increase in combustion pressure by enabling optimal adjustment of the compression ratio at any time. The two-stage VCR connecting rod developed by FEV is already being used in multiple demonstration vehicles.
The collaboration will enable the companies to leverage synergies in the development of the product and devise a cost-efficient solution for serial production. FEV will provide the development and systems expertise, while Hilite, a systems supplier, will provide experience in large-quantity production of components.
Stefan Pischinger, president of FEV Group, said, “We have found Hilite to be a strong partner for the final phase of development for the VCR connecting rod, as they have established themselves as a systems supplier within the market.”
On the subject of the cooperation, he added, “VCR connecting rods are an important technology for the future of the internal combustion engine to considerably reduce CO2 and exhaust emissions in real operation. FEV’s solution has the advantage that it can be incorporated into nearly any engine without an entire redesign.”
