ABSTRACT:
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.
