VGT Variable Nozzle Turbocharger 28231-2F780 Complete Cast Iron Turbo Unit With Electronic Wastegate Control Valve

Product Description

This turbocharger with OE part number 28231-2F780 is a variable geometry turbocharger (VGT) specially designed for matching diesel engines. It adopts an integrated assembly structure including cast iron turbine housing, aluminum compressor housing, electronic actuator, variable nozzle ring and precision rotor assembly. Driven by engine exhaust gas, the turbine wheel drives the compressor to compress intake air, significantly boosting engine power output, torque performance and fuel combustion efficiency. The built-in electronic actuator precisely adjusts the nozzle opening angle according to engine load and speed, effectively eliminating turbo lag at low RPM and preventing overboost at high RPM, delivering stable power output across full operating conditions. All installation flanges, oil supply and return ports fully conform to original engine specifications for direct bolt-on replacement without pipeline modification during engine overhaul.

Key Product Advantages

• Thick nodular cast iron turbine housing, excellent high temperature resistance and thermal fatigue performance, resistant to cracking under long-term exhaust high temperature impact.
• Precision CNC machined turbine and compressor impellers, dynamically balanced at high speed to reduce vibration, noise and shaft wear during operation.
• Integrated electronic VGT actuator with closed-loop signal feedback, accurate real-time adjustment of boost pressure, stable power output and reduced black smoke emission.
• Multi-layer oil sealing structure on the rotating shaft, good anti-leak performance to avoid engine oil consumption caused by turbo oil leakage.
• Standardized flange mounting holes and oil circuit interfaces consistent with original engine layout, convenient disassembly and assembly for maintenance workshops.
