original 293-4071 C7 C9 Rail Fuel Injector for 330 E330D Diesel Engine Part 263-8218 328-2574 20R-8060 new injector original new injector

The C7 Fuel Injector 293-4071 is specifically engineered as a direct-fit replacement for the C7 engine platform, covering the C7 ACERT, C7 Industrial, C7 Generator, C7 Marine, and C7 On-Highway Truck configurations. Its high-pressure electronic fuel injection design and precision-machined nozzle are calibrated to match the factory fuel delivery requirements of the C7 combustion system, ensuring stable rail pressure, precise fuel metering, and consistent spray atomization across all rated operating conditions. Authorized cross references include 293-4071, 2934071, 10R7224, 10R7222, 10R7675, CAT2934071, and -2934071, allowing seamless replacement without the need for system recalibration.

Built with wear-resistant internal components, high-strength alloy steel construction, and corrosion-resistant surface treatment, the 293-4071 injector withstands the thermal cycling, vibration, and high injection pressures typical of C7 service environments. Every unit is 100% factory calibrated, flow tested, and leakage tested to verify OEM-level performance, which directly supports enhanced combustion efficiency, lower fuel consumption, reduced particulate emissions, increased engine response, and improved overall power density throughout the operational life of the engine.

This injector is compatible with 320D, 323D, 324D, 325D, 329D, and 330D excavators, generator sets, marine propulsion engines, Freightliner, Peterbilt, and Kenworth on-highway truck applications, as well as industrial power units, pump drives, compressor systems, and agricultural machinery powered by the C7 powertrain. To preserve calibration integrity, operators should use OEM-quality fuel filters, supply clean diesel free of water contamination, monitor fuel pressure regularly, and perform periodic injector balance testing and return flow inspection.
