A variety of “Turbo” models are mushrooming, although the technology has been relatively mature, but for most of the owners concerned, but still only stay in enjoyment, do not understand that it also needs to be more carefully maintained. For turbocharged models, the following five tips are very important, please keep them in mind!
1 Smashed the gas pedal when start the engine. since the turbocharger is relying on oil to cool down, cold starts when the oil flow is poor, then if the turbocharger is in the high-speed operation, abrasion will be great. Therefore, don’t smashed the gas pedal when start the engine, and don’t put the engine in high speed operation until the engine oil can play a full role in lubrication, so that turbine can extend the life, which is particularly important in winter.
2 A lot of owners like to wait no time to turn off during the long idle time. What they do not know is, when the engine speed is low, turbocharger speed is also low, when the turbo and compressor gas pressure below the bearing body pressure, there will be oil to both ends of the compressor and turbine leakage, the bearing can not be the corresponding lubrication and cooling, while the oil into the compressor may enter the cylinder affect the normal work of the engine, so do not idle for too long.
3 After heading out on the highway in a high-speed and high-load operation, the turbine inlet temperature is very high, the maximum can reach 900 ℃, if the engine immediately stopped, the oil supply will immediately stop, and the turbocharger rotor as the inertia to continue high-speed operation, turbocharger internal retention of the oil will overheat, resulting in damage to bearings and shaft. Therefore, the engine should be idle for about 1 minute, so that the turbocharger rotor speed down.
4 Cleaning the vehicle When the engine and the turbocharger have dust or oil marshes on the outside, be sure not to clean the hot car to prevent the water or cleaning fluid from spilling onto the high temperature turbine to cause deformation or even damage.
5 Don’t follow the rules of using high-quality oil. turbine speed is usually as high as 150,000 / min or more, and most of the car turbines are using floating bearings, that is entirely lubricated by lubricants, so the choice of high quality oil is particularly important. Synthetic engine oil is superior to ordinary mineral oil 3 times the stability of the high temperature and high speed engine to maintain a stable lubrication, provide good lubrication for the turbocharger and the engine, thereby reducing friction and abrasion.
