🔌 Function

The turbocharger uses exhaust flow to rotate the turbine and compressor wheels. The compressor supplies pressurised air through the intercooler, allowing the engine to achieve its rated output while maintaining efficient combustion.

Common signs of failure:

• Loss of boost and reduced vessel performance

• Engine cannot achieve rated rpm

• Excessive black smoke under load

• Blue smoke or increased engine-oil consumption

• Whining, scraping, siren or grinding noises

• Oil accumulation inside the compressor outlet

• Excessive turbocharger shaft movement

• Damaged compressor or turbine blades
