PURPOSE: An accumulative booster system for preventing turbo lag and a method for charging and emitting of an accumulative booster system are provided to improve the starting acceleration performance of a vehicle by preventing turbo lag in the vehicle employing a turbo-charger engine. CONSTITUTION: A boost pressure sensor senses the internal pressure of a plenum chamber. An intake throttle valve(9) is installed at the inlet of the plenum chamber. A throttle position sensor senses the opening state of the intake throttle valve. A vehicle speed sensor senses the speed of a vehicle. An engine control unit controls respective parts of a system to prevent the turbo lag of a turbo-intercooler diesel engine depending on the signals sensed by the sensors. First and second solenoid valves are driven to adjust the opening angle of the intake throttle valve depending on the control of the engine control unit. An accumulative vessel(70) is connected with the plenum chamber via a hose(100) to store or emit high-pressure air. An accumulative valve(80) is installed in the hose to supply the high-pressure air to the plenum chamber from the accumulative vessel.
