C-ummins QSK19 Series injectors are designed for 19L large-displacement QSK19 electronic control engines, as core components of the high-pressure common rail system, adopting B-osch high-pressure common rail technology and ECM electronic closed-loop control. Integrating high-permeability solenoid valves and hard alloy precision parts, they can withstand 320-340bar opening pressure and 1600-2000bar system pressure, fit 600-800 HP, widely used in extreme heavy-duty scenarios.
Relying on 24V solenoid valves to achieve millisecond-level precise control (≤0.3ms), 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 and ISO 9001, fully tested before leaving the factory, they are easy to install and maintain for stable long-term operation.
