Are turbocharger accessories high temperature 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 room to rotate, and the turbine drives the coaxial impeller to rotate. In this way, the impeller will come in from the air filter. The air is compressed and pressurized into the cylinder. As the density of air entering the cylinder is increased, more fuel can be fully burned, which greatly improves the power of the engine and reduces fuel consumption.
After the car engine is cold-started, do not rush to refuel. You should first idling for three to five minutes. This is to increase the oil temperature and improve the activity function, so that the turbocharger parts bearings are fully smoothed. This is especially important in winter. . Otherwise, the turbocharger rotor shaft, bearing, seal ring and other parts are easily worn out due to lack of oil. Regarding vehicles that have parked for a long time (more than a week), the turbocharger must be smoothed before the engine is restarted. The solution is to loosen the oil inlet pipe joint of the turbocharger and pour clean oil with the same brand as the oil pan into the oil inlet. In addition, when replacing the lubricating oil, cleaning or replacing the oil filter, you should fill the turbocharger accessories with lubricating oil according to the above method, and then start the vehicle.
In addition, it is necessary to avoid prolonged idling operation of the turbocharger accessory engine, otherwise it will be affected by the low oil pressure during idling and the floating of the turbocharger rotor shaft, which will lead to the early stage of the rotor shaft, bearing and seal ring. Wear. Under the action of turbocharger accessories, the large fluctuation of the amount of air entering the incineration chamber is equivalent to an increase in the compression ratio under the condition that the volume of the incineration chamber of the engine remains unchanged, which makes the operation intensity of the engine greatly higher. The turbocharged engine has high machining accuracy and strict assembly skills. These all determine that the turbocharged engine is under high temperature, high speed, high power, high torque, and low emission conditions. Therefore, when selecting oil for turbocharged engines, the oil must have outstanding abrasion resistance, high temperature resistance, and simply establish a high-strength oil film. The current component oil or semi-component oil can meet this requirement, so in addition to using the original factory rules, high-quality smooth oils such as component oil and semi-component oil can also be used.
