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.

1. An engine for marine applications, the engine comprising at least one cylinder, a piston disposed within said cylinder, a cylinder head enclosing a first end of said cylinder, a combustion chamber being at least partially defined by said cylinder, said piston and said cylinder head, an intake passage communicating with said cylinder head, a throttle valve disposed along said intake passage, a throttle valve position sensor adapted to detect a position of said throttle valve, a fuel injector positioned downstream of said throttle valve, and a fuel control system that is capable of increasing a supplied amount of fuel in proportion to a rate of change of said position of said throttle valve and that does not increase said supplied amount of fuel for a preset period following engine start.
