Caterpillar original 295050-0411 Common Rail Injector Fuel Injection Nozzle for C4.4 C7.1 320D 323D Excavator Replacement for OEM new injector original new injector

The Caterpillar CAT C4.4 Fuel Injector 295050-0411 is a high pressure common rail diesel injector engineered to deliver precise fuel metering and superior atomization efficiency for demanding industrial and construction applications. Designed for the 4 cylinder inline Caterpillar C4.4 diesel engine platform, including C4.4 ACERT, Tier 3, Tier 4, Stage IIIA, and Stage IV configurations, this injector integrates seamlessly with turbocharged, charge air cooled, and electronic fuel injection systems to support stable combustion and optimized engine performance across a wide range of operating conditions.

Manufactured to OEM standard calibration specifications, the 295050-0411 injector features high pressure resistance, thermal stability, and heavy duty durability, ensuring consistent fuel quantity delivery and enhanced fuel economy. Its corrosion resistant construction and precision internal components contribute to long service life, low emission performance, and reliable operation in harsh working environments such as generator sets, excavators, wheel loaders, backhoe loaders, industrial power units, compressors, agricultural machinery, and material handling equipment.

This injector serves as a direct OEM equivalent replacement for cross reference numbers including 295050-0361, 295050-0401, 295050-0421, 295050-1810, 295700-1200, 571-0940, 370-7287, 418-3229, 370-7286, T409981, 295050-0331, 295050-0320, 295050-0430, and 295050-0450. Proper maintenance, including the use of ultra clean diesel fuel, regular filter replacement, draining of water separators, and monitoring of rail pressure, helps prevent common fault codes such as rail pressure deviation, injector balance fault, fuel quantity correction fault, solenoid circuit fault, and injector coding mismatch.
