INTERNAL COMBUSTION ENGINE FUEL SUPPLY CONTROLLER

摘要

A system (10) for controlling fuel supply to an internal combustion engine via a carburettor. A solenoid valve (4) associated with the fuel supply selectively controls flow of fuel in which a throttle position sensor (2) generates a throttle closed signal and an engine speed sensor (3) generates a first signal indicative of engine speed above a predetermined threshold speed value and a second signal indicative of engine speed below threshold speed value. In use, when both the throttle closed signal and first signal are generated the solenoid valve (4) is controlled to prevent fuel flow, and whenever the second signal is generated the solenoid valve (4) is controlled to permit fuel to flow to the carburettor.
