Claims

[Scope of utility model registration request]

An engine operating state detection means for detecting an engine operating state; a fuel injection amount setting means for setting a fuel injection amount requested by the engine when the detected engine operating state is a steady operating state; and a fuel injection amount setting means for detecting a transient operating state of the engine. a deceleration reduction correction amount setting means for setting a deceleration reduction correction amount of the fuel injection amount based on the engine operation state when the engine deceleration operation state is detected by the engine transient operation detection means; a deceleration reduction increase correction means for increasing the deceleration reduction correction amount set by the deceleration reduction correction amount setting means when a deceleration operation state immediately after acceleration operation is detected by the engine transient operation detection means; and the engine transient operation detection. the fuel injection amount based on the deceleration reduction correction amount set by the deceleration reduction correction amount setting means or the deceleration reduction correction amount increased by the deceleration reduction correction amount when the deceleration operating state of the engine is detected by the means; a fuel injection amount reduction correction means for reducing and correcting the fuel injection amount set by the setting means, and a fuel injection amount reduced by the fuel injection amount set by the fuel injection amount setting means or the fuel injection amount reduced by the fuel injection amount reduction correction means; An electronically controlled fuel injection device for an internal combustion engine, comprising: fuel injection control means for driving and controlling a fuel injection means in accordance with the drive control of the fuel injection means.
