ABSTRACT:
A fuel supply system for selectively increasing the fuel supply to an internal combustion engine suitable for use in outboard motors and the like in response to sensed operating conditions of the engine, such as engine start-up, engine acceleration, and engine knocking. A series of engine operating condition sensors, such as an engine temperature sensor, an engine throttle opening sensor, an engine crank angle sensor, and an engine knocking sensor, detects the occurrence of engine start-up, engine acceleration, or engine knocking and sends a signal to a micro-computer to operate an electromagnetic pump and electromagnetic control valve to supply an additional amount of fuel to the fuel supply passage of the engine.
