Claims

[Scope of utility model registration request]

The intake system is equipped with an electromagnetic fuel injection valve for each cylinder,
In an electronically controlled fuel injection system for an internal combustion engine that controls the fuel injection amount by controlling the pulse width of a drive pulse signal that is output to each of these fuel injection valves in synchronization with engine rotation, an injection time calculation means for calculating an injection time; a cylinder-specific correction amount setting means for setting a cylinder-specific correction amount for each cylinder; a voltage correction amount setting means for setting a voltage correction amount according to a battery voltage; The internal combustion engine is characterized by further comprising a pulse width calculation means for calculating the pulse width of a drive pulse signal to the fuel injection valve for each cylinder by adding the cylinder-specific supplementary component and the voltage correction component to the time. The engine's electronically controlled fuel injection system.
