original 295050-0401 Common Rail Fuel Injector 370-7282 3707282 Diesel Injector for C4.4 C6.4 C6.6 C7.1 Engine Excavator Accessories original new injector

Engineered for high-pressure common rail platforms, the DENSO 295050-0401 fuel injector delivers precise metering and repeatable spray performance for demanding industrial diesel applications. Cross-referenced under 370-7282 and 20R-2478, this injector is a direct replacement solution for operators seeking dependable atomization, stable idle behavior, and consistent combustion efficiency across long duty cycles in construction, power generation, and heavy equipment service environments.

The injector is widely documented for use on C4.4, C6.6, and C7.1 engine platforms, powering equipment such as the 320E and 323E excavators. Its common rail architecture supports multi-pulse injection strategies, enabling optimized fuel economy, reduced particulate emissions, and improved cold-start behavior. Precision-machined nozzle geometry and hardened internal components ensure durable sealing under sustained rail pressures, while the electromagnetic actuator provides fast, accurate response to ECU commands throughout the engine operating map.

Recommended service practices include verifying the OE number and engine serial number before installation, replacing the injector seal kit, inspecting fuel rail pressure, and renewing contaminated fuel filters. During fitment, clean the injector bore, apply OEM torque specifications, install a new copper washer, and confirm the electrical connector lock. After installation, bleed the fuel system, clear ECU fault codes, perform injector coding and idle calibration, and complete a leak test. This structured procedure protects component life and safeguards overall fuel injection system reliability.
