Turbocharged engine on the proper use and maintenance

In the previous section we said a lot of turbocharger characteristics and selection of appropriate oil. Add on turbocharger clean is also very crucial, because the turbocharger shaft and the shaft sleeve with a small gap, the outer ring of the bearing is set between the presence of microalbuminuria and gap, they are referred to as the " floating bearing " high-speed rotation bearing inner, outer ring in rotary. The lubricating oil is not only the lubricating ability requirements are kept clean is also very important. Any small particles stuck in the revolving object will lead to lubricating ability drops, affect the service life of turbine booster.
Therefore, turbocharged engine gives us driving pleasure at the same time, to have the turbo engine has a high speed, high temperature concept. Full load of nearly two hundred thousand RPM high speed, there are nearly 1000 degrees of high temperature. Have asked us to use very attention as
A: not immediately after starting the engine starts, let the engine idle for one or two minutes, winter takes longer, the purpose is to allow the turbocharger to be fully lubricated. This is very important, if the engine starts started running, turbocharger running and oil is not sufficient lubrication for bearings in place, there is injury, if things go on like this will damage early.
Two: vehicle run long-distance or high-speed driving, do not instantly flameout, sudden flameout engine oil will also cease to flow, turbocharger internal heat cannot be oil away, easily lead to the shaft and the shaft sleeve cooling is not uniform and " locking", because the exhaust pipe and turbocharger physical connections, exhaust pipe heat will the turbocharger shell absorption, shell oil will be high temperature carbonization, carbon deposition in the course of time increasing, blocking the lubricating oil circulation leads to inadequate lubrication sleeve and locking " ". Therefore suggested idle after two or three minutes. As a result of idle oil pressure is low, not recommended for long time idle, effects of turbocharger lubrication. Do the following several aspects. I believe a lot of friends already know very well, here we are at the beginning to let more friends to understand and master.
