It is faulty турбокомпрессор?

Lining of hoses and arrangement турбокомпрессор – an exhaust

1 – the coal filter;
2 – a ventilating tube of a fuel tank;
3 – the returnable valve of the coal filter;
4 – турбокомпрессор;
5 – a regulator of pressure of fuel;
6 – an inlet collector;
7 – ventilation картера;
8 – the returnable valve of the coal filter;

9 – a branch pipe throttle заслонки;
10 – a radiator наддувочного air;
11 – a vacuum box of a regulator of pressure of pressurisation;
12 – the valve of switching-off of draught;
13 – the electromagnetic valve of restriction of pressure of pressurisation;
14 – the valve of restriction of pressure of ventilation картера;
15 – the electromagnetic valve of the coal filter.

Before it will be replaced presumably faulty турбокомпрессор, follows along with the defects resulted in the table of the help at malfunctions, to check up following functions or possible sources of defects: knots of adjustment of pressure of pressurisation, giving of fuel, injection, ignition, a compression and the air filter.

 Council: After long full loading allow to the engine to work before deenergizing some time idling.

Dismantle турбокомпрессора

At works on турбокомпрессоре it is necessary to observe cleanliness. Before a detachment carefully clean connecting places and their environment, the dismantled details put only on the pure lining, open knots cover for protection against pollution, establish only pure new details, do not work with compressed air near to a place of repair and do not move the car.

 PERFORMANCE ORDER

  1. Disconnect a wire of weight of the accumulator.
  2. Dismantle the air filter.
  3. Disconnect air hoses from турбокомпрессора.
  4. Water hoses to турбокомпрессору densely press and dismantle.
  5. Unscrew a suspension bracket of an exhaust from a transmission.
  6. Unscrew from турбокомпрессора каталитический the converter (four nuts).
  7. Unscrew from турбокомпрессора a hose of giving of oil.
  8. Unscrew from турбокомпрессора a hose of return of oil.
  9. From below unscrew fixing bolts with which fastens турбокомпрессор to a final collector. Superimposed key SW 12 is for this purpose used bent.
  10. Strongly hold турбокомпрессор during unscrewing and lift it upwards.
  11. Installation: use new nuts and bolts. Grease bolts of a flange of a turbokompressora/knee of a final collector with greasing «G 000 500» in the field of a carving and basic surfaces of heads.
  12. Establish турбокомпрессор with all bolts and nuts in the beginning so that it could move a little. For this purpose fixing nuts/bolts only hardly fasten.
  13. Screw up four fixing bolts for fastening турбокомпрессора at a final collector and tighten taking into account the necessary moment of an inhaling.
  14. Only after that tighten nuts on a reception pipe.
  15. Before connection of a hose of giving of oil it is necessary in the beginning in a connecting branch pipe on the compressor to pour a little fresh engine oil.
  16. After installation турбокомпрессора do not start at once the engine on high turns as compressor greasing is still unreliable.
  17. Allow to it to work within one minute idling.
