Caterpillar original 20R-2284 Fuel Injector Replacement for OEM Parts, 253-0615 for Caterpillar C15 C18 C27 C32 Engines, 374-0750 Cross Reference for L Excavator Applications original new injector

The Caterpillar (CAT) 20R-2284 diesel fuel injector assembly is a precision-engineered fuel system component designed exclusively for CAT C15 series heavy-duty diesel engines, including C15 ACERT, industrial, marine, generator, and heavy-duty truck variants. Manufactured to meet or exceed OEM specifications, it functions as a direct, reliable replacement for original factory units, with verified cross-reference numbers 10R-1273 and 249-0712 to support flexible spare parts matching for B2B procurement needs.

Controlled by the engine’s ECM via electronic signals, the injector meters high-pressure fuel and atomizes it through precision nozzle holes to optimize air-fuel mixing and combustion efficiency. Its industrial-grade build features precision-machined components, OEM calibration, high-pressure and corrosion-resistant materials, an optimized spray pattern, and multi-stage quality testing. These design traits boost engine power and torque, reduce fuel consumption and exhaust emissions, improve cold-start performance, and extend engine service life even in harsh operating environments.

Compatible with excavators, mining trucks, wheel loaders, bulldozers, generator sets, marine equipment, oilfield equipment, and highway trucks, it serves sectors including construction, mining, marine, power generation, and oil and gas. Available in new or remanufactured configurations with a 12-month warranty, it requires standardized installation and regular fuel system maintenance for sustained performance. Buyers should confirm compatibility via engine serial number before placing orders.
