Information:


Illustration 1 g01287440
Turbochargers
(1) Turbocharger
(2) Oil supply line
(3) Oil drain Four turbochargers (1) are used on the rear of the engine. The inlet of the turbine side of each turbocharger is connected to the turbocharger's respective exhaust manifold. The outlet of the compressor side of each turbocharger is connected by pipes to the inlet air lines.
Illustration 2 g01192286
Turbocharger cartridge
(4) Compressor wheel
(5) Bearing
(6) Oil inlet port
(7) Bearing
(8) Turbine wheel
(9) Oil outlet port The exhaust gases go into the exhaust inlet of the turbine housing. The exhaust gases push the blades of turbine wheel (8). Clean air from the air cleaners is pulled through the compressor housing air inlet by the rotation of compressor wheel (4). The compressor wheel blades compress the inlet air. 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 electronic control of fuel delivery. When the engine is operating, the height above sea level also controls the maximum speed of the turbocharger.Bearing (5) and bearing (7) in the turbocharger use engine oil under pressure for lubrication. The oil is sent through the oil inlet line to oil inlet port (6) 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 (9) at the bottom. The oil then goes back to the flywheel housing through oil drain (3) in the support for the turbochargers.
