Turbolader – Symptomen en mogelijke oorzaken van storingen

Black smoke

• Boost pressure control rotary valve/poppet valve does not close
• Lube air filter system
• Dirty compressor or charge air cooler
• Cracked/missing or loose gaskets in the engine air intake
• Excessive flow resistance in the exhaust system / leakage upstream of the turbine
• Foreign body damage to the compressor or turbine
• Fuel system/injection system defective or incorrectly adjusted
• Insufficient oil supply in the peat loader
• Suction and pressure pipe distorted or leaking
• Turbine housing/valve damaged
• Damage to turbo bearings
• Valve guide, piston rings, engine or cylinder liners worn/increased knock

Blue smoke
