1.16. Turbocharger (KG2204T only)
Figure 1-19 Turbocharger
The turbocharger utilizes exhaust gas flowing through
the turbine to spin a compressor. The turbocharger
compressor increases boost pressure and density of
the air/fuel mixture entering the intake manifold
resulting in higher power output compared to the
naturally aspirated engine.
Figure 1-20 Turbocharger Wastegate Adjustment
A wastegate on the turbocharger bypasses exhaust
gas around the turbine when the boost pressure
reaches a maximum limit. Use Spectrum software to
check the boost pressure and adjust the wastegate
linkage, if necessary, to achieve a maximum boost
pressure of 180 kPa absolute.
1.17. Turbocharger Oil Lines
(KG2204T only)
Figure 1-21 Turbocharger oil lines
The turbocharger bearings require oil for lubrication
and cooling. Oil is fed to the turbocharger bearings
from the oil supply line on the top side of the bearing
housing and returned to the oil sump through a line
connecting the bottom side of the bearings to the
sump.
