Abstract: 본발명은적분제어를이용한가변터보차져의폐루프제어방법에관한것이다. 본발명은, 차량의 ECU로부터변속단의변경여부를판단하여, 변속단의변경시에적분제어출력값을 0으로리셋하거나또는각 변속단에따라적분제어의출력초기값을미리정해진값으로설정함으로써, 부스트압의하향조정에따른출력저하를수반하지않고서도, 오버부스트에대하여효과적으로대응할수 있도록한 것을기술적특징으로한다.

Abstract: PURPOSE: Logic for pre-controlling boost pressures is provided to control a boost stably because a boost pressure pre-control map is dualized according to applications of a LP-EGR system. CONSTITUTION: Logic for pre-controlling boost pressures comprises a boost pressure pre-control map(M), a valve driving determination unit(110), a map switch unit(s1, s2). The boost pressure pre-control map comprises a LP boost pressure pre-control map(M1, M3), a HP boost pressure pre-control map(M2, M4). A vane duty of a turbine is set in the boost pressure pre-control map according to a speed of an engine(Erpm) and amount of fuel(Einj). The valve driving determination unit determines an application state of the LP-EGR system according to an opening state of a mixing valve or a LP-EGR valve(V_LP). The map switch unit sets a map as the LP boost pressure pre-control map in order that a vane opening degree of the turbine is set through the LP boost pressure pre-control map of the boost pressure pre-control map if the LP-EGR system is applied.

Abstract: PURPOSE: A back pressure valve is provided to prevent an engine from turning off even if a flap is completely closed by preventing the complete cutoff of exhaust gas. CONSTITUTION: A back pressure valve comprises a flap(10). The flap has a flap body area and an inner space area and changes the flowing amount of gas using the cutoff area change of an inner space. The ratio of the flap body area and the inner space area is reduced by reducing the diameter size of the flap and forming one or more holes in the flap.
