Fuel injection control system for marine engines

摘要

An internal combustion engine is fuel injected. A controller either detects or calculates engine speed, throttle angle and a rate of change of the throttle angle. A first fuel injection amount is preset during a preset period of time following engine starting and subsequently controlled by the controller. While being controlled, an amount of fuel injected is comprised of two components: a base amount determined by engine speed and throttle angle and an additional amount determined by throttle angle and a rate of change in throttle angle. Ignition timing also can be varied in the two component manner as well.
