A turbocharger control system includes an on-off valve disposed in an engine-side end of a passage interconnecting a turbocharger and an engine. When the accelerator pedal is released while the engine is in operation, the on-off valve is closed to store air under pressure in the passage. When the engine is accelerated again, the on-off valve is opened to supply the stored air to the engine, thus supercharging the engine. Therefore, any turbocharger time lag produced when the engine is accelerated again can be reduced. If the pressure of intake air stored in the passage is not increased, a motor mounted on the rotatable shaft of the turbocharger is energized to assist in rotating the turbocharger.

A system for controlling a turbocharger associated with an internal combustion engine, comprising: a passage interconnecting an air outlet of the turbocharger and an air inlet of the engine; opening and closing means, disposed in an end of the passage which is connected to said air inlet, for selectively opening and closing said end of the passage; detecting means for detecting the amount of depression of an accelerator pedal which controls the output power of the engine; and control means for controlling said opening and closing means to close said passage end to store intake air in said passage, when the amount of depression of said accelerator pedal is reduced at a speed higher than a predetermined speed as detected by a signal from said detecting means, and for controlling said opening and closing means to open said passage end to release the stored intake air and supply the stored intake air to the engine, when the amount of depression of said accelerator pedal is increased.
