<p>PURPOSE:To improve output and accelerating property by operating a branch path and a waste gate respectively to open and close to raise supercharging pressure in high knock limit and low temperature when water temperature and intake temperature have predetermined values or less. CONSTITUTION:When water temperature and intake temperature exceed predetermined temperatures, a servo motor 9 is operated to close a control valve 10. The output pressure of a compressor 1 acts on a diaphragm unit 11 for operating a waste gate 4 through a waste gate operating pressure path 5 and opens the waste gate 4 when it exceeds a predetermined pressure. When water temperature and intake temperature are under predetermined temperatures, the servo motor 9 is operated to open the control valve 10 so that pressure in said path 5 leaks and pressure acting on the diaphragm 11 is reduced to operate the waste gear 4 in the closing direction.</p> |
