      C-ummins QSK23 Series injectors are designed for 23L large-displacement QSK23 electronic control engines, as core components of the high-pressure common rail system, adopting C-ummins HPI high-pressure injection technology and ECM electronic closed-loop control. Integrating high-permeability solenoid valves and hard alloy precision parts, they can withstand 340-360bar opening pressure and 1800-2200bar system pressure, fit 760-950 HP, widely used in extreme heavy-duty scenarios.

     Relying on 24V solenoid valves to achieve millisecond-level precise control (≤0.28ms), these injectors have uniform and delicate atomization, which can effectively optimize fuel combustion efficiency, reduce carbon deposits and exhaust emissions, meeting Tier3/4 emission standards. Complying with C-ummins original standards, ISO 9001 and TS16949, fully tested before leaving the factory, they are easy to install and maintain for stable long-term operation.
