Product Introduction
In the evolving landscape of heavy-duty diesel propulsion, the efficiency of the fuel injection system is paramount. The 10R-7672 is a premium remanufactured diesel injector specifically engineered for Caterpillar® C4.4 and C6.6 industrial and marine engines. Unlike standard replacement parts, this component is rebuilt to meet strict OEM specifications, ensuring it integrates seamlessly into high-pressure common rail (HPCR) architectures. By utilizing advanced solenoid actuation and precision-machined nozzle geometries, the 10R-7672 restores optimal combustion dynamics, directly addressing the rigorous demands of modern emission standards and operational efficiency.
⚙️ Technical Specifications & Data
To ensure compatibility and peak performance, the following technical data defines the 10R-7672 diesel injector:
Part Number: 10R-7672
Engine Application: Caterpillar® C4.4 (Industrial/Marine), Caterpillar® C6.6
System Type: Electronic Control Common Rail (ECCR)
Actuation Method: High-Speed Solenoid Valve
Operating Pressure: Compatible with high-pressure rails exceeding 1600 bar (23,200 psi)
Atomization Standard: Optimized for spray patterns ensuring droplet sizes ≤20μm for complete combustion.
Flow Rate Tolerance: Calibrated to maintain injection quantity deviation within ±2%, ensuring cylinder balance.
🔬 Internal Structure & Material Integrity
At the heart of the 10R-7672 lies a robust solenoid assembly and a precision valve group. The internal components are manufactured from high-grade hardened steel to withstand the extreme shear forces and abrasive nature of modern ultra-low sulfur diesel (ULSD). The nozzle features a multi-hole design (typically 6 to 8 orifices) engineered to create a specific spray cone angle (150°-170°). This structural integrity prevents needle valve sticking-a common failure mode in older injectors-and ensures that the high-pressure fuel is atomized effectively before entering the combustion chamber.
