CUMMINS Factory QSK23 Excavator Engine Parts Fuel Injector 6560-11-1114 6560-11-1112 6560-11-1113 For Komatsu PC1250-7 PC1250-8 SAA6D1170E-3 6D170 Original New Injector

The 6560-11-1114 fuel injector is a premium OEM-grade component exclusively engineered for c-ummins QSK23 series diesel engines, a core part of the high-pressure injection system that ensures the engine’s exceptional power density, fuel efficiency, and long-term reliability. Tailored to meet the rigorous demands of heavy-duty applic-ations such as mining, oil and gas, and large-scale construction equipment, this injector is designed to work seamlessly with the QSK23’s 23.15L displacement and high-performance turbocharged system. It delivers precise fuel delivery at pressures up to 2000 bar, with ultra-fine atomization (≤40 microns) that ensures complete combustion, effectively reducing exhaust emissions and improving fuel economy by 9-12% compared to standard injectors. Equipped with a fast-responding solenoid (opening/closing time <0.15ms), it enables sophistic-ated multi-stage injection (pre-injection, main injection, post-injection) to optimize combustion efficiency, minimize engine noise and vibration, and extend the engine’s service life to over 20,000 hours before the first overhaul. Constructed with high-quality materials, including heat-treated high-strength alloy steel for the body, tungsten carbide-coated nozzle tip (HRC70), and high-temperature resistant copper solenoid coil, this injector boasts excellent durability, wear resistance, and adaptability to extreme operating temperatures (-40°C to 165°C). Every unit undergoes strict factory testing, including pressure calibration, flow measurement, spray pattern validation, and leakage checks, to ensure perfect compatibility with c-ummins QSK23 engine control systems and compliance with global emission standards. With a comprehensive set of OEM cross reference numbers, it serves as a direct and reliable replacement for original parts, offering hassle-free installation and a 12-month unlimited mileage warranty, making it the ideal choice for maintaining the performance and longevity of c-ummins QSK23 series engines in harsh industrial environments.
