Typical example (1) Compressor wheel (2) Bearing (3) Oil inlet (4) Bearing (5) Turbine wheel (6) Air inlet (7) Exhaust inlet adapter (8) Oil outletThe turbine side of the turbocharger is connected to the exhaust manifold. The compressor side of the turbocharger is connected by pipes to the aftercooler housing.The exhaust gases go into the exhaust inlet adapter of the turbine housing. The gases push the blades of turbine wheel (5) .Clean air from the air cleaners is pulled through the compressor housing air inlet by the rotation of the compressor wheel (1). This compression gives the engine more power because the compression allows the engine to burn additional fuel with greater efficiency.The maximum speed of the turbocharger is controlled by the engine's control of fuel delivery. When the engine is operating, the height above the sea level also controls the maximum speed of the turbocharger.Bearing (2) and bearing (4) in the turbocharger use engine oil under pressure for lubrication. The oil is sent through the oil inlet line to the oil inlet port (3) at the top. The oil then goes through passages in the center section for lubrication of the bearings. The oil goes out of oil outlet port (8) at the bottom. The oil then goes back to the oil pan.
