The turbocharger runs on the energy of the exhaust gases. Gas passes through the turbine, spinning its wheel. The turbine wheel is attached to the shaft, at the other end of which the second wheel is fixed. This wheel rotates in its own housing and compresses the intake air on its way to the intake manifold.
Between the turbocharger and the intake manifold, compressed air passes through the intercooler. The intercooler is installed 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 during compression (cold air is denser than warm air), resulting in increased engine power.
boost pressure (intake manifold pressure) is limited by a bypass valve, which, at a certain pressure, passes the exhaust gas past the turbine wheel.
The turbine shaft is lubricated under pressure from the main lubrication system. Shaft "floats" on an oil pad. Through the return pipe, the oil flows into the sump.
The turbocharger bearings are cooled by the circulating coolant. After the ignition is turned off, the pump continues to pump coolant for several minutes, preventing overheating of the bearings and extending their service life.
Warning! The turbocharger operates at extremely high speeds and temperatures. Some precautions must be taken to avoid premature damage to the turbine.
Do not accelerate the engine to high speed immediately after starting, especially if it is not warmed up.
Always return the engine to idle before turning off the ignition - do not accelerate before turning off the ignition, the turbine will rotate quickly without lubrication.
Allow the engine to idle for a few minutes before turning off the engine after running at high speeds.
Observe the recommended oil and filter change intervals, and use the oil specified in Specifications varieties. Neglect of these recommendations may cause carbon deposits to form on the turbine shaft, which may result in a malfunction.
