Section 6 Operation notice of turbo- charger diesel engine
Turbocharger mounted at the exhaust pipe of the diesel engine. Exhaust
gas discharged from the cylinder entry turbocharger casing through exhaust
pipe drives impeller of the turbine, then drives impeller of the compressor
push the pressed air filtered by air filtered into cylinder. Due to more air
pressed into cylinder, more fuel can be injected and burned more enough,
then diesel discharge more power and lower displacement. Meanwhile, it can
be compensated the power when the diesel engine operates at plateau
area( turbocharger with discharge valve owns advantages such as large
torque at low speed , high and low speed performance)
Caution for diesel operation as followed:
1 Favorable lubrication is the key to extend service life of turbocharger and
diesel engine, because turbocharger is a precise part. The faster speed of the
rotor, the higher temperature of the turbine (usual above 640
℃
), and the
pressure of the lubricant set up rotor shaft (called floating bearing) to work. So
the lubricant shall be clear and pressurized, with high quality. Pressured
lubricant filtered from lubricant system be used at turbocharger. Speed of
turbocharger is much higher than that of diesel, then inferior quality, dirty or
poor lubricate capability, all can damage the turbocharger. So seriously affect
the diesel to work well. Therefore, it is necessary to use CD oil for diesel,
change oil, filter core of oil filter, clear oil sump
and oil pump suction regularly
according to the technical maintenance requirement of diesel operation manual.
If the damage of the turbocharger and diesel is caused by the above caution
such as use inferior quality oil, not change oil, filter core of oil filter, clear oil
sump
and oil pump suction regularly , causes oil aging, deterioration result in
coking of oil or blocking lubrication pipe, the responsibilities shall be borne by
the customers.
