Abstract: PURPOSE: An exhaust gas recirculation amount control method according to the combustion pressure of an internal combustion engine is provided to improve the quality of an engine by controlling the recirculation amount of exhaust gas until noise and vibration are optimized. CONSTITUTION: An exhaust gas recirculation amount control method according to the combustion pressure of an internal combustion engine comprises following steps. The inner combustion pressure of a cylinder mounted inside internal combustion engine is detected(S100). Maximum gradient is calculated on a crank angle. The standard deviation of the maximum gradient is computed(S120). When the standard deviation is smaller than the set standard value the steps are repetitively performed(S130). When the standard deviation is higher than the set standard value, the recirculation amount of the exhaust gas is reduced(S140).

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 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).
