Abstract

PURPOSE: To obtain a proper supercharging effect covering a wide revolutional speed range by a method wherein a flow amount controlling means is provided in a branched passageway, provided so as to bypass a turbine of a supercharger, to control it in accordance with a compared result between an electric signal indicating a condition of an engine and a preset value.
CONSTITUTION: When an engine 10 is in a condition of a flow revolving speed, an amount of fuel injected by an injection pump 20 is detected by a detector 110 in a controlling circuit 100 and an output thereof is impressed to a comparator 150 through a multiplier 130. Thereupon, the output of the multiplier 130 is lower than a divided voltage of a voltage divider 140, therefore, a transistor 160 is put on through the comparator 150 and a coil 61 of a solenoid switching valve 60 is excited. Consequently, a servo chamber 53 of a negative pressure operator 50 is opened to open air through a diaphragm 62 and a controlling valve V is shut through a diaphragm 54. Thereby, all of exhaust gas discharged into an exhaust passageway 14 is given to a turbine 32 of a supercharger 30.
