C-ummins QSK60 Series injectors are designed for 60.2L V16 large-displacement QSK60 electronic control engines, as core components of the high-pressure common rail system, adopting C-ummins HPI ultra-high pressure injection technology and ECM electronic closed-loop control. Integrating high-permeability solenoid valves and hard alloy precision parts, covering core models such as 4088428 and 2881089, they fit 1500-2500 HP, widely used in extreme heavy-duty scenarios.
Relying on 24V solenoid valves to achieve millisecond-level precise control, these injectors have uniform and delicate atomization, which can effectively optimize fuel combustion efficiency, reduce carbon deposits and exhaust emissions, meeting Tier3/4 and Euro V emission standards. Complying with C-ummins original standards and relevant quality systems, fully tested before leaving the factory, they are easy to install and maintain for stable long-term operation.
