In the turbocharger, two turbines are installed on one shaft, located in two housings.
The turbines are driven by exhaust gases, which accelerate the turbines to 12,000 rpm.
The charge turbine, rotating at high speed, increases the flow of fresh air into the engine cylinders, providing better filling of the cylinders and increasing engine power. The discharge pressure is 0.45–0.55 bar; when this pressure is exceeded, the safety valve opens and passes part of the gases past the turbine into the exhaust system.
The turbocharger is manufactured with high precision and can only be replaced.
Replacement
1. Moisten the nuts on the exhaust manifold and exhaust pipe with a rust remover.
2. Remove ground wire from battery.
3. Remove pressure (1) and suction (2) hoses.
4. Mark and remove the hoses going to the solenoid valve (2) (1 - oil return hose).
5. Unscrew the exhaust pipe from the turbocharger.
6. Remove the return and pressure oil hoses from the turbocharger.
7. Bend the tongues of the fixing plates (1), unscrew the nuts (2) and remove the turbocharger (4) (3 - exhaust manifold, 5 - pressure oil hose).
8. Install turbocharger in reverse order of removal.
