Abstract
A turbocharger control system, utilized in an internal combustion engine, which includes a bypass passage bypassing exhaust gases directly to an exhaust treatment device around a turbocharger turbine, and a waste gate valve connected to an actuator by means of a link mechanism. The waste gate valve is a normally opened type valve and is maintained so as to be opened in case problems are encountered in the actuator operating the waste gate valve or in the link mechanism attached to the actuator, thereby reducing resultant damage to pipe members forming a passage from a turbocharger compressor to a throttle valve.
