Bosch’s Remanufactured Diesel Injectors are produced at the same Bosch facility as the new diesel injectors. All wearable parts and critical components are replaced with genuine Bosch parts,and the latest original equipment production technology is used. Bosch remanufactured injectors include all OE updates, so they can often be superior to the OE injectors that they replace.

It features a high-pressure (over 2,000 bar or 200 MPa or 29,000 psi) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles). Third-generation common rail diesels now feature piezoelectric injectors for increased precision, with fuel pressures up to 2,500 bar (250 MPa; 36,000 psi).^[1]

High pressure injection delivers power and fuel consumption benefits over earlier lower pressure fuel injection, by injecting fuel as a larger number of smaller droplets, giving a much higher ratio of surface area to volume. This provides improved vaporization from the surface of the fuel droplets, and so more efficient combining of atmospheric oxygen with vaporized fuel delivering more complete combustion.
