TURBOCHARGER SYSTEM AND CONTROL METHOD FOR THE SAME

摘要

A turbocharger system of an embodiment includes: a wastegate valve; an electrically-operated actuator configured to adjust a valve lift of the wastegate valve; a temperature acquisition unit configured to acquire a target temperature which is a temperature of the turbocharger body or a temperature correlating with the temperature of the turbocharger body; and an actuator controller configured to control the electrically-operated actuator on the basis of the target temperature. The temperature acquisition unit acquires the target temperature, and the actuator controller controls the electrically-operated actuator on the basis of the target temperature.

1. A turbocharger system comprising:
a turbocharger body including a compressor housing and a turbine housing; a turbine shaft rotatably supported by the turbocharger body, and linking a turbine impeller in the turbine housing and a compressor impeller in the compressor housing; a wastegate valve configured to make part of a fluid to be guided to the turbine impeller flow to a downstream of the turbine impeller while bypassing the turbine impeller; an electrically-operated actuator connected to the wastegate valve, and configured to adjust a valve lift of the wastegate valve; a temperature acquisition unit configured to acquire a target temperature which is any one of a temperature of the turbocharger body and a temperature correlating with the temperature of the turbocharger body; and an actuator controller configured to control the electrically-operated actuator on the basis of the target temperature.
