ABSTRACT:
A charging control apparatus including means for shortening a running-up period of the second turbocharger with an exhaust bypass valve when an instant engine speed is low, so that torque shock during the transition from one-turbocharger-operation to two-turbocharger-operation is decreased. During rapid acceleration at high engine speeds, an exhaust switching valve is opened at once. Further, the reference engine speed and the reference intake air quantity for switching to two-turbocharger-operation are varied in accordance with the shift gear position, so that an optimum switching to two-turbocharger-operation is obtained.
