Abstract: PURPOSE: A device and a method for controlling turbine speed of a turbo charger engine are provided to reduce a fin noise of a turbo charger engine in a low load area of an engine. CONSTITUTION: It is confirmed whether speed of revolution of an engine is speed of an idle area(S11). It is confirmed whether the engine has a load(S13). If the speed of revolution of the engine is speed of the idle area and the engine has the load, a waist gate valve is forcibly opened to slow down speed of revolution of a turbine(S15). If the speed of revolution of the engine is higher than the speed of the idle area and the engine has a high load, it is judged whether the waist gate valve is to be opened. According to the result of the judgement, the waist gate valve is normally opened and shut for controlling the speed of revolution of the turbine(S17).
