9. Intake/exhaust system
158
Function
1. Turbine
The exhaust gas that is discharged from combustion
chamger passes through turbine housing conveying an
energy to turbine wings to give the rotating power,
This is called as the turbine and in order not to influ-
ence a bad effect at bearing part, there are the seal
ring and heat dissipator.
2. Compressor
It is connected to the same shaft with the turbine to
make a revolving assembly, and receive the revolvi
ng
f
orce of turbine, and sends air to the suction manifold
by suctioning and compressing it. This is called as th
e
c
ompressor.
3. Bearing
1) Thrust bearing force is applied to the turbine wheel
and an arrangement is made for the shaft not to shift.
2) journal bearing (floating bearing) is adopted and it
forms the double oil films at the in out surfaces in
comparison to the general stationary type so that t
he
b
earing may be able to rotate independently and
consequently the double layers of films act as th
e
d
amper to make the slipping speed on the beari
ng
s
urface less than the rotaing speed of shaft so that
the dynamic stability may be obtained.
4. Sealing at compressor shaft
Inorder for the compressed intake air and lubricatin
g
o
il not to leak, a seal plate and a seal ring are made
to the double structures.
