The turbocharger runs on the energy of the exhaust gases. The gas passes through the turbine, spinning its wheel. The turbine wheel is attached to a shaft, on the other end of which a second wheel is attached. This wheel rotates in its own casing and compresses the intake air on its way to the intake manifold.
Between the turbocharger and the intake manifold, the compressed air passes through the intercooler. The intercooler is mounted on the left side of the car, behind the front bumper. The purpose of the intercooler is to cool the forced air, which heats up when compressed (cold air is denser than heated air), as a result, the engine power increases.
Boost pressure (intake manifold pressure) limited by a bypass valve, which, at a certain pressure, allows the exhaust gas to pass past the turbine wheel.
The turbine shaft is lubricated under pressure from the main lubrication system. The shaft "floats" on an oil cushion. The oil flows through the return pipe into the sump.
The turbocharger bearings are cooled by circulating coolant. After the ignition is turned off, the pump continues to pump coolant for several minutes, preventing the bearings from overheating and extending their service life.
Warning! The turbocharger operates at extremely high speeds and temperatures. To avoid premature damage to the turbine, certain precautions must be taken.
Do not rev the engine to high rpm immediately after starting, especially if it is not warmed up.
Always return the engine to idle mode before turning off the ignition - do not accelerate before turning off the ignition, the turbine will spin quickly without lubrication.
Before turning off the engine after running at high speed, allow it to idle for a few minutes.
Follow the recommended oil and filter change intervals and use the oil specified in Specifications grades. Neglect of these recommendations may cause carbon deposits to form on the turbine shaft, which may result in a malfunction.
