PURPOSE: A turbo charger control apparatus is provided to reduce a consumption of a fuel by removing an exhaust pressure unnecessary to an activation of an engine at an idle region and to enhance a durability of the engine by reducing a boost pressure of a suction manifold side at a high speed region. CONSTITUTION: A turbo charger control apparatus is so constituted as to be supplied an air to a suction manifold(7) by activating a turbo charger by an exhaust gas drained to an exhaust manifold(3) of an engine(1). The turbo charger is connected to an actuator(9) to control an RPM(revolution per minute) according to a driving state of the engine(1). The actuator(9) is so constituted as to be controlled a bypass amount of the exhaust gas by controlling a poppet by a boost pressure supplied from a boost pressure sensor mounted to an exhaust manifold(3) side. The actuator is connected to a pipe(15) to control according to the driving state of the engine and to activate a control pressure of a vacuum pump(11) and the exhaust pressure control valve(13). The vacuum pump is so connected to be controlled according to an engine speed(a), an engine load(b) and the suction manifold boost pressure(c) and the vacuum pressure is so connected to be served to the pipe, thereby controlling by an electronic control unit received a sensed signals of the elements. The exhaust manifold(3) is connected to the pipe(15) by the exhaust pressure valve(13) installed at a pipe(17) to activate the actuator(9) by the exhaust pressure. |
