(6) Bearing
(7) Turbine housing
(8) Turbine wheel
(9) Exhaust outlet
(10) Oil outlet port
(11) Exhaust inlet
The turbocharger is mounted on the outlet of the
exhaust manifold. The exhaust gas from the exhaust
manifold enters the exhaust inlet (11) and passes
through the turbine housing (7) of the turbocharger.
Energy from the exhaust gas causes the turbine
wheel (8) to rotate. The turbine wheel is connected
by a shaft to the compressor wheel (3).
As the turbine wheel rotates, the compressor wheel
is rotated. The rotation of the compressor wheel
causes the intake air to be pressurized through the
compressor housing (2) of the turbocharger.
