Turbocharger is driven using the engine exhaust turbine, no matter how advanced it is a mechanical device, because it often in high-speed work environment, working under high temperature, turbocharger exhaust turbine side of the temperature at 600 degrees, pressure device speed is very high, so in order to ensure the normal operation of the turbocharger, its proper use and maintenance is very important. We should follow the following main methods:
1, High speed engine for a long time, you can not turn off immediately. The reason is the engine work, some of the oil supply turbocharger rotor bearings for lubrication and cooling, running the engine suddenly shut down, the oil pressure fell rapidly to zero, oil lubrication is interrupted, the heat inside the turbocharger oil can not be taken away, when the turbocharger turbine heat will spread to the middle part of the bearing shell supporting the heat can not be quickly taken away, while still under the turbocharger rotor inertia under the effect of high-speed rotation. This will cause the turbocharger shaft and the sleeve between the "bite" and damage the bearings and shaft.
In addition, the engine suddenly turned off, this time the high temperature exhaust manifold, the heat will be absorbed into the turbocharger housing, and will remain in the internal turbocharger oil boiled . When this piled up a long time it will block the inlet, causing sleeve oil, turbine speed between the shaft and sleeve wear. So turn off the engine idle for three minutes before the role of the turbocharger rotor speed decreased. Also worth noting is also not suitable for long-turbo engine idle, the general should be kept within 10 minutes.

2, Select the oil must pay attention to. As the role of the turbocharger, the air entering the combustion chamber so that the quality and volume are greatly improved, the engine more compact, more reasonable, a higher compression ratio, the higher strength of the engine work. Machining accuracy is also higher, more stringent technical requirements for the assembly. All decisions of the turbocharged engine's high temperature, high speed, high power, high torque, low-emission characteristics of the work. At the same time also determines the engine's internal components to withstand higher temperatures and greater impact, compression and shear forces working conditions. Therefore, the choice of turbocharged cars motor oil when it is necessary to take into account the special nature of the oil used must wear resistance, high temperature, the establishment of lubricating oil film block, high film strength and stability. The synthetic oil or semi-synthetic oil just to meet this requirement, it is best to use the original oil in addition to the provisions of the oil, can also use synthetic oil, high-quality semi-synthetic oil lubricants.
3, Engine oil and filter must be kept clean to prevent debris from entering, because the turbocharger shaft and the sleeve with the gap between the very small, if the decline in oil lubrication capacity, it will cause premature retirement engine turbocharger .
4, The turbocharger should always check that no abnormal noise or unusual vibration, oil pipes and fittings for leaks.
5, Turbocharger rotor high precision bearings, maintenance and installation work environment is very strict, so when the turbocharger failure or damage to the designated repair station should repair, rather than to the general repair shop .
