HE400WG wastegate turbocharger is produced by Dongfeng 49th Factory for Cummins heavy-duty diesel engines. It increases cylinder air density by compressing intake air, greatly lifting low-speed torque and combustion efficiency, cutting fuel consumption and exhaust pollutants, conforming to domestic and international mainstream heavy-duty vehicle emission standards, and is a high-quality aftermarket replacement spare part for commercial vehicles and engineering equipment.

Overview

Product Details

Produced strictly following Cummins and Holset original design specifications, dimensional standards and production techniques, Assy No.3783070 features unified structural layout, installation hole dimensions and boost pressure calibration values with interchangeable original parts, supporting direct bolt-on installation with no modifications required. It thoroughly resolves common turbo malfunctions including weak climbing power, dense black exhaust smoke, excessive engine oil burning and serious turbo delay brought on by aging and component damage.The rotor assembly undergoes ultra-precise high-speed dynamic balance testing. All finished turbochargers are subjected to air tightness detection, boost pressure calibration and comprehensive appearance quality inspection before shipment, able to run steadily for a long time amid harsh working conditions: sustained heavy load, repeated start-stop cycles and high exhaust temperature environments.

Product Advantages

High-strength Material & Reliable Structure

Turbine wheel and compressor impeller adopt high-temperature resistant nickel alloy material, outstanding thermal fatigue resistance to endure the high exhaust temperature working environment of large-displacement heavy-duty diesel engines
Advanced floating oil film bearing system guarantees stable rotor rotation, effectively prevents oil leakage faults, fits long-distance transportation and engineering heavy-load frequent start-stop conditions
External pneumatic wastegate realizes real-time precise regulation of intake boost pressure, avoids engine damage caused by overboost, and delivers sensitive power output at low rotating speeds

OEM Standard Precision Production

Overall outline, mounting hole layout and boost parameters fully match original factory components, plug-and-play installation without pipeline adjustment
High-precision dynamic balanced rotor lowers operating vibration and noise, noticeably extending the overall service life of the turbocharger
Multiple rounds of air tightness testing eliminate oil seepage, compressor surge and abnormal exhaust noise problems
