started, immediately shut down the
engine for overhaul.
4) Operation of supercharger
The supercharger is installed at the rear upper
end of engine, consisting of turbine assembly
and pump impeller assembly. The exhaust gas
discharged by the engine will drive the turbine
and the pump impeller on the same shaft to
rotate at a high speed, discharging the
compressed air into the engine air intake pipe
to increase the intake pressure and increasing
the engine power.
The rotor in the supercharger normally runs at
a very high speed (about 70,000–100,000 rpm).
The rotor bearing is forced lubricated with
hydraulic oil provided by engine main oil duct.
The oil supply will be cut off as long as the
engine shuts down.
Precautions during operation:
a. To start the engine, run it at idle speed
for 2-3 min without depressing the accelerator
forcibly in this process, and do not apply load
until the oil pressure and temperature are both
normal (especially for start-up in cold days);
otherwise, the damage caused by early wear can
is likely to occur to bearing and sealing ring
