Reasons for regular cleaning of turbocharger rotor.
Most of the problems of turbocharger rotors are caused by the destruction of the sealing property of the framework between the turbocharger and the air inlet, which causes large-scale engine oil burning. The key reason for the destruction of the skeleton seal is that the cycle time for oil replacement is too long or the application of fake and inferior automobile oil causes the fluctuation of the main rotating shaft of the turbocharger to lack lubrication and heat removal, thus destroying the skeleton seal and causing oil leakage. Generally, the turbocharger will not start until the vehicle speed reaches 3500 rpm, and it will rapidly increase to 6000 rpm. When selecting automobile oil, high-end fully synthetic oil should be selected. The larger characteristic of the turbine is its high power, which depends on its fine design scheme and processing technology, and also determines its harsh office environment. Therefore, it has very high regulations on the cleaning and defense of lubricating grease, and the engine oil and filter element must be kept clean to avoid other debris entering. Because the distance between the rotating shaft and bearing of the turbocharger is small, if the function of oil lubrication is reduced, the turbocharger will report too early; In addition, it is necessary to clean or replace the air filter in time to prevent dust and other debris from entering the centrifugal impeller of the high-speed turbocharger; The authoritative experts also suggested that the car buyer should not use the turbocharger for a long time if the ambient gas cleanliness is poor and the soot content is high.
When the car starts, be sure to drive gently and safely. Because the turbocharger is cooled by car oil, the cold car starts, and the car oil lubrication is poor. At this time, if the turbocharger is running at high speed, it will be very worn. The proper way is to wait for two or three minutes at high speed, wait for the wettability of the automobile oil to be good, and then let the diesel engine rotate at high speed, so that the turbocharger can get sufficient lubrication; In addition, do not stop the fire immediately after the car runs at high speed. Due to the sudden stop of the fire, the lubrication of the automobile oil will stop, and the heat generated in the turbocharger cannot be carried away by the automobile oil, which is very easy to cause the "seizure" between the rotating shaft and the bearing of the turbocharger. In addition, after the diesel engine suddenly stops firing, the flow of the car oil to the turbocharger stops. The heat generated by the high temperature will boil the car oil inside the turbocharger out of carbon deposits, which will then plug into the oil hole, resulting in less bearing oil. A good turbocharged diesel engine is technically efficient. It can be ignited more fully by increasing the air index entering the engine combustion chamber, thus increasing the power. However, in addition to the power increase of the turbocharger diesel engine, the work pressure and average air temperature caused by the work are also greatly increased.
