Maintenance of turbocharger rotors.


Maintenance of the turbocharger rotor

1. The engine must be kept at idle speed until engine lubrication pressure is built up. Accelerating the engine immediately after starting will result in the turbocharger operating at maximum speed before its bearings have been adequately lubricated. Operating the turbocharger with inadequate lubrication can damage its bearings. Repeatedly doing this can lead to premature turbocharger damage.


2. Before stopping the engine, the temperature and speed should be gradually reduced from the maximum. Turbochargers have higher operating speeds and higher continuous operating temperatures than other machines. When the engine is working at maximum output or maximum torque, the turbocharger speed and temperature also reach the maximum, when the engine suddenly stops at this working point, it will make the engine, especially the turbocharger out of order. This requires the engine to idle at medium speed or to operate under light load for a period of time, while still maintaining the engine's lubricating oil pressure and the amount of air flowing through the cooling system. Following these guidelines will prevent the turbocharger from running without oil for long periods of time and will prevent the formation of carbon deposits, which are formed when residual oil in the bearings or intermediate housing is carbonised by the action of thermal reabsorption.


3. Pre-lubricate the turbocharger. The turbocharger needs to be pre-lubricated after changing the lubricating oil or doing any servicing (including draining the oil). Coil the crankshaft several times before starting the engine. After starting the engine, allow it to idle for a period of time to build up the entire lubrication cycle and pressure before going into high speed.


4. Low temperatures make starting the engine a must with caution.

When the ambient temperature is too low or the vehicle is not used for an extended period of time, this can affect the ability of the engine to establish normal lube oil pressure and flow. In such cases, the engine must idle for several minutes after starting before it can be put into high speed operation.


5. Long periods of engine idling should be avoided.

When the gas pressure in the turbo and compressor is too low and the speed of the turbocharger shaft is too low, lubricating oil can leak through the sealjian into the turbo and compressor species. This does not normally cause mechanical damage, but can foul the impeller and cause the user to complain.
