<p>PURPOSE:To surely restrain the occurrence of knocking, by discharging fuel from fuel injection pump to an intake-air passage when the degree of knocking is small while opening a waist gate valve when the degree of knocking is large. CONSTITUTION:An electromangetic fuel injection pump 17 is disposed instead of a mechanical accelerator pump in the fast system 6a of a carburettor 6 upstream of the venturi section. Further, there is provided a waist gate valve 15 for opening and closing bypass passage bypassing a turbine 14 in a supercharger 12. When a microcomputer 33 which receives an output signal (e) from a knock sensor 41, etc. detects the occurrence of knocking, it delivers a signal (c) instructing the opening of the waist gate valve 15 if the degree of knocking is small, to a waist gate controller 16. Further, if the degree of knocking is large, a signal (d) instructing the discharge of fuel is delivered to the fuel injection pump 17.</p> |
