Caterpillar original 295050-0361 Fuel Injector 3707281 Replacement for OEM, C7.1 C4.4 C6.6 Engine, Excavator Truck Tractor Parts, Cross Reference 295050-0331 295050-0401 original new injector

The Caterpillar 295050-0361 is a genuine original common rail diesel injector engineered for the CAT C4.4 engine family, covering C4.4 ACERT, industrial, generator, power unit, and construction engine variants. Built to strict Caterpillar OEM specifications, it matches factory calibration and combustion requirements to eliminate fitment and performance risks for replacement and rebuild programs. It supports global interchangeability across OEM, remanufactured, and aftermarket channels, serving as a reliable B2B sourcing option for engine and equipment maintenance.

Operating within Caterpillar’s high-pressure common rail fuel injection system, it receives real-time signals from the engine control module (ECM), which monitors engine speed, load, fuel pressure, intake airflow, and exhaust emissions to adjust fuel delivery. Its precision solenoid and nozzle deliver exact fuel metering and an OEM-matched spray pattern, optimizing atomization for stable combustion, higher power output, lower fuel consumption, and reduced particulate and NOx emissions. Heavy-duty construction with high-temperature resistance, corrosion protection, and hardened wear-resistant parts extends service life in severe-duty construction and mining environments.

Suited for a broad range of global industrial use cases, this injector works with construction machinery, mining equipment, generator sets, agricultural equipment, material handling systems, marine auxiliary engines, and industrial power units. It also supports OEM engine manufacturing and diesel engine rebuilding operations, with cross-reference compatibility with related CAT part numbers to streamline global parts sourcing. Each original new unit delivers consistent, long-lasting performance for demanding industrial B2B applications.
