ABSTRACT:
An electronically controlled, fuel injection method and apparatus, wherein fuel is supplied by an electromagnetic fuel injection valve into an intake system. The rate of fuel injection when the engine is cold is increased or decreased in relation to a difference between a detected engine torque and a predetermined optimum torque. Consequently, good operational performance of the engine at low engine temperature is ensured, irrespective of variations in ambient factors such as atmospheric pressure, etc. and variations in engine characteristics.
