HX50 Wastegate Type Turbocharger For Sinotruk HOWO WD615 Engine

The OE part number is VG1560118227. This Turbocharger (HX50 Wastegate Type) is the critical air intake boosting component of heavy‑duty truck engine system. It is professionally matched with Sinotruk WD615 series engine models, recovering exhaust gas energy discharged from engine combustion chamber to drive turbine wheel, and then drives compressor wheel to compress fresh intake air and deliver dense air into engine cylinder, improving air-fuel mixing ratio fully. It significantly raises engine power and torque output, optimizes fuel combustion efficiency and reduces exhaust smoke under heavy load.
It effectively solves common engine faults caused by aging, wearing and damage of old turbochargers, such as insufficient engine power output, continuous black smoke emission during acceleration, excessive engine oil consumption, obvious turbo whistle noise during operation, oil leakage at turbine end and compressor end, rotor shaft stuck and turbo locking failure. Damaged turbo will further lead to insufficient cylinder air intake, aggravated engine wear and even engine breakdown. This premium turbocharger can well eliminate these typical failure risks for Sinotruk HOWO heavy‑duty trucks.
It adopts cast iron turbine housing and aluminum alloy compressor housing. The rotor assembly undergoes high-precision dynamic balance calibration at ultra-high speed, ensuring stable high-speed rotation under long-time heavy load, high temperature and bumpy working conditions. Built-in wastegate structure can intelligently adjust and control boost pressure automatically to prevent overboost pressure, effectively protect engine cylinder and other related components. Factory-calibrated installation flange and mounting hole positions support direct plug-and-play installation, maintaining tight fitting without air leakage during long-term vehicle vibration.

① Applicable vehicle models
Suitable for Sinotruk HOWO series heavy trucks equipped with WD615 diesel engine, including logistics tractors, bulk cargo transport vehicles, engineering dump trucks and long‑haul transportation heavy‑duty vehicles. Widely applied for after‑sales maintenance, fleet overhaul and spare parts stocking projects.
② Adaptation System
Belongs to HOWO Engine System, sub‑category of engine intake boosting parts. Precisely matches WD615.62, WD615.78UN engine, exhaust manifold and related peripheral engine components. Fits installation cavity perfectly without drilling, cutting or any modification to vehicle structure. No extra debugging needed, ready for direct installation after replacement.
③ Original Factory Reference Number
Corresponding OE Number: VG1560118227. Interchange OE reference: VG1560118229 (HX50W for WD615.47, 336/371HP), VG1560118228 (Turbo Cartridge / Repair Kit). All products are strictly manufactured according to original factory drawing data and mold standards, achieving full dimensional consistency and 100% accurate interchangeability with genuine OEM turbocharger.
④ Interchangeability
Produced fully complying with OEM dimensional and performance criteria. Core parameters including turbine housing size, compressor housing dimension, rotor assembly clearance, rated boost pressure and wastegate control range are completely consistent with original spare parts. It can directly replace the factory turbocharger, greatly shortening on‑site maintenance debugging time and cutting labor service costs. Separate turbo cartridge and repair kit VG1560118228 are available for individual rotor core replacement to save maintenance cost.
⑤ Additional Services
We provide professional compatibility verification based on customers' HOWO vehicle year, WD615 engine power configuration and actual failure phenomenon. Meanwhile, detailed disassembly & assembly operation guidance and matching turbo repair kit recommendation lists are available. Our technical team offers full‑process installation support to avoid turbo shaft damage, oil leakage and insufficient boost pressure faults triggered by mismatched spare parts or non‑standard installation.

The turbine housing adopts high strength cast iron, with excellent heat resistance and thermal fatigue resistance, capable of enduring high-temperature exhaust gas from continuous engine operation. The compressor housing is lightweight aluminum alloy with fast heat dissipation performance. The turbine wheel and compressor impeller are forged high-temperature alloy, resistant to high speed and thermal deformation. The rotor shaft adopts high-strength alloy steel, matched with floating bearing system to reduce friction loss. The built-in wastegate valve assembly is made of heat-resistant metal material to realize stable boost pressure regulation. The whole unit has outstanding adaptability to heavy‑truck harsh working conditions, resisting high temperature, vibration and exhaust corrosion.

The cast iron turbine housing surface adopts high-temperature anti-oxidation coating treatment, effectively isolating erosion from high temperature exhaust, moisture and dust to prevent long‑term oxidation and crack. The aluminum compressor housing surface is sandblasted for anti-corrosion, the internal air passage is precisely polished to reduce air flow resistance and improve intake efficiency. All threaded mounting holes are precision machined and deburred, ensuring stable assembly and no loosening under long-time vibration. The rotor assembly is treated with high temperature anti-wear coating to reduce wear and extend service life.

Turbine housing casting, impeller machining and turbo assembly are completed by advanced fully automatic CNC production equipment. Core processing procedures are finished in a constant‑temperature dust‑free workshop to eliminate internal material stress of the workpiece and avoid later deformation during vehicle operation. Key indicators such as dimension tolerance, rotor dynamic balance, boost pressure stability, sealing performance and noise value are inspected piece by piece with professional precision testing equipment. All finished products pass 100% full inspection before delivery, covering appearance defect detection, static and dynamic air tightness test, high-temperature cycle test and long-time anti-fatigue durability test. Each batch of goods is screened per OEM standards to fully meet heavy‑load operation and long‑service‑life requirements of HOWO WD615 engine intake boosting system.
