Caterpillar original 292-3780 Common Rail Diesel Fuel Injector 10R-7669 for 320D Engine, Replacement for OEM 306-9380, Cross Reference 320-0680 original new injector

As a precision-manufactured fuel system solution built exclusively for Caterpillar C6 Series diesel engine platforms, the 292-3780 common rail diesel fuel injector adheres to strict Caterpillar OEM engineering requirements for fit, form and performance. It is fully compatible with C6 and C6.4 inline six-cylinder 6.4L direct injection diesel engines, covering industrial, construction equipment and power generation engine variants, and matches official replacement part 10R-7228 and cross-reference 10R7228.

Integrated into the engine’s high-pressure electronic fuel injection system, this injector is controlled by the engine ECM, which collects real-time data on engine load, speed, air intake volume, fuel demand and operating temperature to trigger injection at exact timings. Its precision-machined nozzle atomizes pressurized diesel into microscopic droplets to optimize combustion, delivering improved fuel efficiency, lower fuel consumption, reduced smoke emissions, stabilized idle performance, reduced engine noise and enhanced cold-start capability.

Constructed from hardened alloy steel with an anti-corrosion coating to withstand heavy-duty industrial operating conditions, the 292-3780 injector supports extended service life, lower maintenance costs and improved equipment productivity. It is validated for use across CAT 320D-series excavators, H-series wheel loaders, C6 generator sets and industrial power units deployed in construction, mining and earthmoving worksites globally.
