ABSTRACT:
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.
