Method for operating fuel injector in a computer controlled fuel injection type internal combustion engine

摘要

An internal combustion engine provided with a system for controlling the predetermined idling rotational speed NF of the engine, and a system for operating a fuel injector so that the injector is de-energized when the rotational speed is higher than Ncut and the injector is energized when the rotational speed is lower than NRTN. A value of Ncut is the product of NF and a predetermined positive value alpha 1 and the value of NRTN is the product of NF and a predetermined positive value alpha 2 (< alpha 1).
