Abstract

An engine control device for electronically controlling fuel injection of an engine is disclosed. The engine control device includes algorithms for instantaneously calculating fueling requirements in accordance with sensory inputs corresponding to engine operating conditions and throttle position. The fueling requirements are instantaneously reflected as modifications of the duration of fueling signals supplied to the fuel injectors, so that instantaneous fueling changes are effected. Fuel is conserved, and engine responsiveness improved in the current or presently occurring fuel injection cycle as a result of the immediate responsiveness of the engine control device operation.
