HE300WG wastegate turbocharger is developed by Holset for Dongfeng Cummins (DCEC) QSB6.7 displacement diesel engines. It compresses intake air to raise cylinder air density, improves fuel combustion efficiency and low-speed torque output, reduces fuel consumption and exhaust emissions, complies with national and international mainstream emission standards, and serves as premium aftermarket replacement spare parts for commercial vehicles and engineering machinery equipment.

Overview

Product Details

Manufactured strictly in accordance with Holset and Cummins original design drawings, dimensional tolerances and standardized production processes, Assy No.5500364 shares consistent structural layout, installation dimensions and boost pressure calibration parameters with interchange parts, supporting direct bolt-on installation without any modification. It effectively solves common turbo faults such as insufficient power during climbing, heavy black smoke, abnormal engine oil consumption and obvious turbo lag caused by ageing and damage.The rotor assembly undergoes ultra-precise high-speed dynamic balance testing; all finished turbochargers pass air tightness inspection, boost pressure calibration and comprehensive appearance quality check before delivery, capable of stable long-term operation under harsh working conditions including continuous medium load, frequent start-stop and high exhaust temperature environments.

Product Advantages

High-strength Materials & Stable Structure

Turbine wheel and compressor impeller adopt high-temperature resistant nickel-based alloy material, with excellent thermal fatigue resistance to adapt to the high exhaust temperature working condition of QSB6.7 medium-displacement diesel engines
Advanced floating oil film bearing system ensures smooth rotor rotation, effectively avoids oil leakage failures, and adapts to frequent start-stop and medium-load working scenarios of road vehicles and engineering equipment
External pneumatic wastegate accurately adjusts intake boost pressure in real time, prevents engine damage caused by overboost, and brings quick low-speed power response

OEM Grade Precision Manufacturing

Overall shape, mounting hole position and boost parameters are fully consistent with original factory accessories, plug-and-play installation without pipeline transformation
High-precision dynamically balanced rotor reduces operation vibration and noise, effectively prolonging the overall service life of the turbocharger
Multiple air tightness tests eliminate oil seepage, compressor surge and abnormal exhaust noise issues
