Abstract

PURPOSE: To accomplish a fully supercharging effect further prevent an abnormal rise of exhaust gas temperature in an engine, by providing a controller reducing supercharge pressure at engine speed not less than a prescribed value.
CONSTITUTION: A bypass passage 10 is provided in an exhaust passage 3 to as to detour an exhaust gas turbine 9 of a supercharger, and a solenoid valve 11 is provided in the bypass passage 10. Supercharge pressure is controlled by open-close controlling said valve 10 with a controller 14. This controller 14 is of such constitution that a comparator circuit 14a is provided to compare output of a speed sensor 12 with output of a set voltage generating circuit 14b and generate output at actual speed of an engine at least a prescribed value then the solenoid valve 11 is opened by output of the comparator circuit 14a through a solenoid valve drive circuit 14c. In this constitution, supercharger pressure can be controlled in accordance with engine speed capable of preventing an abnormal rise of exhaust temperature.
