Caterpillar original For Caterpillar C7.1 Engine, Common Rail Fuel Injector 370-7281, 295050-0361, for Excavator 336 E330D E336D and Diesel Truck CHEVROLET S10 PICKUP 2.8 original new injector

Specially engineered for CAT C4.4 series diesel engines, the 370-7281 high-precision industrial fuel injector is a core component of the engine’s high-pressure common rail fuel delivery system. It delivers precise fuel metering, optimized atomization and accurate injection timing, directly supporting stable power output, improved fuel efficiency and compliant emission control. Built to strict OEM standards, it operates reliably under sustained high-temperature and high-pressure conditions common in heavy-duty industrial environments.

Constructed from hardened alloy steel with a protective anti-corrosion coating, this injector resists extreme wear and corrosion to extend service life in harsh operating settings. It features an electronically controlled direct injection design and multi-hole spray nozzle, with an operating pressure range of 1800–2200 bar to ensure uniform atomization and complete combustion. CNC machining guarantees compliance with exact OEM tolerances for consistent performance.

The 370-7281 injector is compatible with all listed C4.4 engine variants and fits a wide range of CAT heavy equipment, from loaders and excavators to generators and tractors. It serves construction, mining, agricultural and power generation sectors, and includes a 12-month / 1000-hour warranty for operational assurance. Cross reference numbers 209-4394, 320-7281 and 0R-7281 simplify parts matching for efficient replacement workflows.
