In a 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 supercharger 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 supercharger pressure is 0.45-0.55 bar; when this pressure is exceeded, the safety valve opens and allows some of the gases to pass past the turbine into the exhaust system.
The turbocharger is manufactured with high precision and can only be replaced.
Replacement
1. Wet the exhaust manifold and exhaust pipe mounting nuts with a rust converter.
2. Remove the ground wire from the battery.
3. Remove the pressure (1) and suction (2) hoses.
4. Mark and remove the hoses going to the electromagnetic valve (2) (1 – oil return hose).
5. Unscrew the exhaust inlet pipe from the turbocharger.
6. Remove the return and pressure oil hoses from the turbocharger.
7. Bend back the tabs of the fixing plates (1), unscrew the nuts (2) and remove the turbocharger (4) (3 – exhaust manifold, 5 – pressure oil hose).
8. Install the turbocharger in the reverse order of removal.
