Are turbocharger parts heat resistant?
What are turbocharger accessories? It is an exquisite air compressor installed on the exhaust pipe of the engine. It uses the exhaust gas discharged from the engine to propel the turbine in the turbine chamber to rotate, and the turbine drives the coaxial impeller to rotate. The air is compressed and pressurized into the cylinder. Due to the increased air density entering the cylinder, more fuel can be fully burned, thus greatly improving the power of the engine and reducing fuel consumption.
After the car engine is cold started, do not rush to refuel. It should be idling for three to five minutes. This is to increase the oil temperature and improve the movement function, so that the bearings of the turbocharger accessories can be fully smoothed. This is especially important in winter. . Otherwise, components such as the rotor shaft, bearing, and sealing ring of the turbocharger will be easily worn out due to lack of oil. For vehicles that have been parked for a long time (more than a week), be sure to smooth the supercharger before restarting the engine. The method is to loosen the oil inlet pipe joint of the supercharger and pour clean oil with the same trademark as the oil pan into the oil inlet. In addition, when replacing the lubricating oil, cleaning or replacing the oil filter, you should add lubricating oil to the turbocharger accessories according to the above method, and then start the vehicle.
In addition, it is necessary to avoid the long-term idling operation of the turbocharger accessories engine, otherwise the oil pressure will be low during idling, and the turbocharger rotor shaft will be affected by floating, which will lead to the early stage of the rotor shaft, bearings and seal rings. wear. Under the action of the turbocharger accessories, the air volume entering the incineration chamber fluctuates greatly. Under the condition that the volume of the combustion chamber of the engine remains unchanged, it is equivalent to improving the compression ratio, which greatly increases the working intensity of the engine. High machining precision for turbocharged engines, rigorous assembly skills. All of these determine that the turbocharged engine is under the conditions of high temperature, high speed, high power, high torque and low emission. Therefore, when selecting the oil used in the turbocharged engine, it is required that the oil used must have good anti-wear and high temperature resistance, and easily establish a high-strength oil film. The current composition oil or semi composition oil can meet this requirement, so in addition to using the original standard oil, high quality smooth oil such as composition oil and semi composition oil can also be used.
