Turbocharger 9
General description
Warning! Turbochargers operate at high speed and at high temperatures. Keep fingers, tools and other
objects away from the inlet and outlet ports of the turbocharger and avoid contact with hot surfaces.
A turbocharger, is fitted between the exhaust and induction manifolds. The turbocharger is driven by exhaust
gases and supplies air to the engine at more than atmospheric pressure. The turbocharger is lubricated by oil
from the oil filter head. The oil passes through the bearing housing of the turbocharger and returns to the
lubricating oil sump.
Some turbochargers are fitted with a waste-gate unit. This unit, which is controlled by boost pressure, allows
some of the exhaust gases to by-pass the turbine rotor at higher engine speeds. With this arrangement, the
turbocharger can be designed to be more effective at lower engine speeds.
Always use the manufacturer’s instructions and specialist assistance to fit the service kit for the turbocharger.
Caution: Do not use a caustic solution to clean the components of the turbocharger because the turbocharger
will be damaged.
