Abstract

PURPOSE: To enhance the rate of fuel consumption by introducing such a control that a waste gate valve opens when the engine operating condition is at least with high revolving speed and with low/medium load, and relieving rise of the supercharge pressure caused by increase in the engine load.
CONSTITUTION: An engine concerned is equipped with a turbo-supercharger, in which pressurization is made for the suction air by a compressor 4B directly coupled with a turbine 4A driven by the exhaust gas. The exhaust passage 11 of this engine is provided with a waste gate passage 12 as a bypass to the turbine 4A, and a waste gate valve 13 opened and closed by an actuator 14 is installed at the upstream end of this waste gate passage 12. The actuator 14 is of diaphragm type, and leads the supercharge pressure to No.1 working chamber 14e and also introduces the suction neg. pressure to No.2 working chamber 14f via a communication path 16 on which a three-way solenoid valve 17 to be duty controlled is installed. Thereby such control shall take place that the waste gate valve 13 opens when the engine operating condition is at least with high revolving speed and with low/medium load.
