Federal-Mogul has developed an electrical brushless diesel fuel pump for on- and off-highway engines with significantly improved durability to help keep heavy-duty vehicles working longer. The technology suits 12 V and 24V applications. Fuel pumps are an essential part of diesel powertrains, transferring the fuel from the tank to the injection system. A typical electric pump is more fuel-efficient than those driven directly by the engine; however, the carbon commutator and brushes found in conventional pumps are subject to wear, which is accelerated by high engine vibration and variations in diesel fuel.
