커민스 4BT3.9 turbocharger

Compatible Models: Cummins 4BT3.9 series diesel engines Suitable Equipment: Excavators, skid-steer loaders, cranes, various agricultural machinery, and generator sets Housing Material: Constructed with a high-quality, heat-resistant alloy cast iron housing. It offers excellent resistance to thermal fatigue and pressure, ensuring the housing remains free from deformation or cracking during prolonged operation under high thermal loads. Core Components: Features a precision-balanced rotor assembly that responds rapidly to speed changes. This effectively boosts engine torque across various RPM ranges and significantly reduces turbo lag. Dynamic Balancing: Undergoes rigorous high-speed dynamic balancing before leaving the factory to ensure smooth, noise-free operation at high speeds, thereby greatly extending the service life of the turbocharger and bearings. Sealing Performance: Utilizes professional multi-layer metal seals with superior pressure and oil resistance. This prevents oil leakage into the intake system and effectively protects engine cylinders from secondary wear. Compatibility: Fully matches Cummins' original design standards. Flange mounting holes and intake/exhaust port layouts are precision-engineered to ensure efficient and seamless on-site installation.
