Abstract: Improved thermal management of Internal Combustion Engines (ICEs) can help meet stringent emissions regulations in the road transportation sector. This strategy requires high-efficiency pumps capable of controlling the cooling flow precisely and efficiently. Compared to centrifugal pumps, screw-type volumetric ones maintain high efficiency even when operating far from the design point, resulting in significant energy and emissions reductions.
