A fuel-injection system ( 1, 1', 1'', 1 ''') for an internal-combustion engine ( 2 ), of the type provided with: a tank ( 3 ) for collection of the fuel; compressor system ( 4 ) for drawing in the fuel from the tank ( 3 ) and making it available at high pressure to an storage volume ( 7 ); at least one injector ( 8, 8', 8 ''') hydraulically connected to the storage volume ( 7 ) for taking in the fuel at a high pressure from the storage volume ( 7 ) and injecting it into a respective combustion chamber ( 12 ) of the engine ( 2 ); a fluid line ( 17 ) connecting the storage volume to the tank; and pressure-regulator means ( 19 ) in the storage volume ( 7 ) set along the fluid line ( 17 ); the pressure-regulator systems ( 19 ) are set hydraulically downstream of the storage volume ( 7 ) so as to enable a continuous flow of fuel through the storage volume ( 7 ) itself.
