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.
