<p>PURPOSE:To prevent a surging of a supercharger by providing a bypass passage which communicates the outlet of a compressor of the supercharger and the outlet of a turbine and a control valve in the bypass passage, which is opened at a deceleration. CONSTITUTION:A compressor 4 of a supercharger 3 is connected with the upstream line of a carbureter 7 and a turbine 5 of the supercharger 3 is driven by an exhaust gas of an engine 1. A bypass passage 11 is provided to communicate the outlet of the compressor 4 and the outlet of the turbine 5. A control valve 12 is equipped in the bypass passage 11 and opened on the basis of information of a deceleration condition detected by receiving signals of a supercharged pressure sensor 13, a suction pressure sensor 17, a revolution number sensor 16 and an engine exhaust gas prssure sensor 14. Therefore, a surging of the supercharger 3 occurring at a deceleration and a resulting damage of it may be pevented.</p> |
