Exhaust turbine booster is worked by the exhaust gas that is discharged by the diesel engine. The booster’s lubrication is taken from the lubrication system of the engine and then transported to oil inlet of the middle cast of the booster through the connection hose, the oil return of the booster flows to the crankcase through a tube, depending on the gravity.

As the temperature of the booster’s bearing is high, which needs a certain amount of lube to confirm the cooling and lubrication, also it is very sensitive to the impurities of the lube, so it needs to install filters.
