3. After the cold car starts, it should be idling for 1-2 minutes. Do not slam the throttle to make the engine run at high speed.
If the accelerator pedal is pressed after starting, the turbine shaft speed will rise rapidly (up to 70,000-100,000 rpm), and the oil pressure will not rise as fast as the speed, and lubrication between the turbine shaft and the floating bearing cannot be quickly formed. The oil film will cause early wear due to dry friction due to lack of oil. In this regard, pay special attention to the start of the car in the morning (especially in winter).
4, can not idle for a long time (not more than 10 minutes).
The heat dissipation and lubrication of the supercharger mainly depends on the flow of the oil. Long-term idle operation, low oil pressure, slow flow, can cause poor heat dissipation of the supercharger, resulting in early wear of the turbine shaft and floating bearings due to overheating.
5. Do not turn off the flame immediately after a long time driving at high speed.
After a large load or high speed operation of a turbocharged vehicle, do not immediately turn off the flame. Allow the engine to continue to idle for about one minute. After the turbine speed and temperature are lowered, turn off the engine to avoid sudden heat loss. The oil gel deteriorates, causing damage to the turbocharger.
Some people say that the current turbine engine has a time-delay cooling system that can be turned off immediately, and the time-delay cooling system can continue to provide cooling for the turbine. However, Lao Hou believes that the cooling intensity of this system is far less powerful than the engine's own cooling system. In order to better protect the engine, it is better to let the engine idle for a while, wait for the turbine temperature to drop, and then turn off the flame.
