Which is better charger or turbocharger

Turbocharger: function, damage, symptoms

Symptoms of turbocharger damageSymptom:Possible mistakes:Measure:Turbocharger whistlingIf the turbocharger whistles with increasing speed, the shaft is damaged or knocked out. The whistling noise is caused by the metallic friction.Overhaul / repair turbochargerBluish smokeIndicates an oil leak in the turbocharger, for example due to a knocked out charger shaft. The oil for storing and cooling the shaft gets into the exhaust and burns.Overhaul / repair turbochargerIncreased oil consumptionTurbocharger bearing damage, defective or clogged oil supply lines.Check the turbocharger's oil lines and replace if necessaryBlack smokeCan be caused by insufficient air supply. During combustion, there is a disproportion in favor of the fuel content, black smoke is produced. A leak in the fresh air line could be the cause.Check the hoses and connections of the suction or compressed air lines for leaks, replace if necessary. Low-lying lines (charge air cooler) can loosen / damage if they hit the ground.Loss of power IIf there is a permanent lack of power, the compressor wheel can be damaged. Broken blades no longer push enough air into the cylinders.New compressor wheel, overhaul turbocharger, protect the intake tract from foreign matter in the future.Loss of power IIIf the VTG unit is covered with soot, the guide vanes jam. The charger can only build up pressure late or no longer at all.Dismantle and clean the loader, eliminate the cause of the increased soot formation.Too high boost pressureThe valve for boost pressure regulation, control lines or vacuum unit is defective.Replace vacuum unit, make valve free to move, repair control line.Noises from the turbochargerBack pressure in the exhaust system too high, compressor wheel or turbine wheel damaged, leak in front of the turbine (for example on the manifold).Check exhaust for damage, repair compressor or turbine, eliminate leak.
