Product Introduction
The 2645A734 diesel injector is a high-performance common rail injection component engineered for Caterpillar / Perkins C4.4 and C6.6 diesel engines, widely deployed across construction machinery, power generation, and industrial applications. Designed as a direct OE-spec replacement, this injector ensures optimized atomization, fuel efficiency, and emissions compliance in modern diesel systems.
Cross-referenced with part numbers such as 10R7672, 320-0680, and 306-9380, the 2645A734 injector integrates seamlessly into existing common rail systems, maintaining calibration compatibility and injection accuracy.
⚙️ Engineering Logic – Built Around High-Pressure Common Rail Demands
Unlike traditional mechanical injectors, the 2645A734 operates within a high-pressure electronically controlled common rail system, where injection timing and fuel quantity are precisely regulated by the ECU.
Key engineering principles include:
High-pressure capability: Typically supporting injection pressures exceeding 1600–2000 bar, ensuring ultra-fine atomization
Solenoid-actuated control valve: Enables rapid response injection cycles
Multi-hole nozzle design: Produces uniform spray distribution for complete combustion
Fog-type atomization pattern: Improves mixing efficiency and reduces particulate formation
This structure is critical for Tier 3 / Tier 4 diesel emission strategies and fuel economy optimization.
