What are the common failures of turbochargers?
1 Answers
Turbocharger failures: 1. Foreign object ingestion failure in turbocharger: The compressor side is damaged by foreign objects, possibly due to poor intake pipe sealing allowing unfiltered air to enter the compressor wheel, or failure to replace air filters as required or using inferior filter elements; 2. Radial damage failure by foreign objects: Damage to components within diesel engine cylinders or foreign objects entering the exhaust manifold during maintenance - any foreign object can disrupt the dynamic balance of the turbocharger rotor, eventually leading to rotor seizure or shaft fracture; 3. Contaminated lubricating oil failure in turbocharger: The engine uses non-compliant lubricating oil filters or inferior filter elements, with the filter element being punctured during operation or the engine's main oil passage filter becoming blocked.
