Two turbochargers (1) are mounted on the rear of the engine. The turbine side of each turbocharger is connected to the respective exhaust manifold. The compressor side of each turbocharger is connected by pipes to the aftercooler housing.

The exhaust gases flow into the exhaust inlet of the turbine housing. The 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 action of the compressor wheel compresses the inlet air. This compression provides more power because the compressed air allows the engine to burn additional fuel with greater efficiency.
The maximum speed of the turbocharger is controlled by the electronic control of fuel delivery. When the engine is operating, the height above the sea level also controls the maximum speed of the turbocharger.
Bearing (5) and bearing (7) use pressurized engine oil for lubrication. The oil flows through oil inlet port (6) at the top. The oil flows through passages in the center section to lubricate the bearings. The oil flows out of oil outlet port (9) at the bottom. The oil drains into the flywheel housing through oil drain line (2).
