Turbocharger

Turbocharger intake cooling pipe

Charge air cooler intake pipe

Turbocharger oil return pipe

The turbocharger consists of two elements, a turbine and a compressor both installed on a
single shaft and are contained within a turbocharger housing. The turbocharger and
exhaust manifold are a combined assembly and are not supplied separately.

The turbocharger bearings are supplied, cooled and lubricated by oil from the engine
through the oil supply tube. Oil is returned to the oil pan through the oil return pipe. In
addition the turbocharger is also cooled by engine coolant which is supplied from the engine
and cooled down by the radiator.

The turbine element of the turbocharger uses the energy of the exhaust gas to drive the
compressor. The compressor draws in air from the air cleaner, through the turbocharger
which increases pressure and flow of air. Turbocharged air is then forced through the
charge air cooler where air temperature is cooled before it reaches the intake manifold.

The turbocharger boost pressure is governed by means of a wastegate control valve. The
wastegate redirects some of the exhaust gas past the turbine so over boosting does not
occur. The wastegate control valve is controlled by a wastegate control solenoid which is
preset during manufacture and must not be tampered with.
