Since the turbocharger is often operated at high speed and high temperature, the temperature of the turbocharger exhaust gas turbine is about 600 °C, and the supercharger rotor rotates at a high speed of 8000-11000 r/min. Therefore, in order to ensure the normal operation of the supercharger, The following points should be noted:
Don’t start the car and move immediately.
After the engine is started, especially in the winter, it should be idling for a period of time to allow the lubricant to fully lubricate the bearings before the supercharger rotor runs at high speed. Therefore, after starting, do not slam the throttle to prevent damage to the turbocharger oil seal.
Do not turn off the car immediately.
After the engine has been running at high speed for a long time, it cannot be turned off immediately. When the engine is running, some of the oil is supplied to the turbocharger rotor bearing for lubrication and for cooling. After the running engine suddenly stops, the oil pressure drops rapidly to zero, the high temperature of the turbocharger turbine part is transferred to the middle, and the heat in the bearing support shell cannot be quickly taken away, while the supercharger rotor is still rotating at high speed under inertia. Therefore, if the machine suddenly stops during the engine heat state, it will cause the oil remaining in the turbocharger to overheat and damage the bearing and the shaft. In particular, it is necessary to prevent the sudden flameout after a few feet of the throttle.
