Caterpillar original 2645A747 Common Rail Fuel Injector 10R-7672 for Caterpillar Excavator 320D, C6.6 Engine, Replacement for OEM Parts, Compatible with 320-0680 original new injector

Engineered for precise fuel delivery in demanding diesel applications, the 2645A747 is an electronically controlled common rail injector designed for Caterpillar and Perkins engine platforms. Working with the engine ECU, it releases high-pressure fuel through precision-machined nozzle holes at precisely timed intervals, calculated from engine speed, load, boost pressure, coolant temperature, and throttle position. The resulting ultra-fine atomization and optimized spray pattern promote efficient combustion, higher fuel efficiency, stronger power output, lower emissions, improved cold-start performance, and reduced engine vibration.

This OEM-standard replacement injector covers an extensive Caterpillar and Perkins application range. It fits CAT C4.4, C6, C6.4, C6.6, C7, and C7.1 engines, plus Perkins 1104D and 1106D series platforms, and powers equipment such as CAT 320D, 321D, and 323D excavators, 924H, 928H, 930H, and 938H wheel loaders, 420E and 430E backhoe loaders, and 120M, 140M, and 160M motor graders.
