CONTROL APPARATUS FOR CUTTING IN AND OUT AN EXHAUST-DRIVEN TURBOCHARGER

摘要

A control for the engagement and disengagement of an exhaust gas turbocharger in which the charging air pressure of the internal combustion engine is used as control magnitude for the engagement and disengagement. Unfortunately, this charging air pressure exhibits oscillations with large amplitudes after each engagement and disengagement which could trigger faulty shifting operations in the control. To alleviate this problem, the control line (44) between the charging-air line and the control slide valve members (40, 41) is always closed off when these oscillations occur and their negative effects on the control are thereby prevented.
