🔌 Function

The turbocharger uses exhaust-gas energy to drive the turbine and compressor. The compressor supplies pressurised air through the charge-air cooler, enabling the D6 engine to develop its rated output and torque under sustained marine loads.

Common signs of failure:

• Reduced boost and poor vessel acceleration

• Engine cannot reach rated full-load rpm

• Excessive black smoke under load

• Blue smoke or increased oil consumption

• Loud whining, siren, scraping or grinding noise

• Oil accumulation in the compressor outlet or charge-air cooler

• Excessive radial or axial shaft movement

• Compressor or turbine blade damage
