As in all turbomachinery, the dimensional accuracy of turbocharger components is critical in achieving thermodynamic and aero-dynamic efficiency. Inaccurate parts geometry can translate directly into increased fuel consumption. For example, only the slightest variance in the clearances between compressor and turbine wheels and their adjacent casings can cause a major deterioration in your engine’s performance and fuel efficiency. Likewise, steps at joints and rough surface quality on gas and air path parts can affect aerodynamic efficiency by causing turbulence.
Therefore, accurate component geometry and excellent surface condition is vital in the production of new Original Parts. Moreover, during a repair or overhaul, our service engineers take great care to get the best match of tolerances between turbine and compressor wheels and the casings they run in.
For components like turbines, compressor impellers, shafts and casings, the materials of these vital rotating and gas and air path parts are chosen to withstand extreme heat and abrasive particles as well as the highest mechanical stresses.
