Abstract
An improvement in an electronically controlled fuel injection apparatus which determines the amount of fuel injection and, in a deceleration mode, stop the fuel injection until an engine rotation speed falls below a predetermined fuel injection reinitiation rotation speed if the current engine rotation speed is higher than a predetermined fuel injection stop rotation speed. When an air conditioner compressor is active, the fuel injection stop rotation speed, or the fuel injection stop rotation speed and the fuel injection reinitiation rotation speed, or the fuel injection reinitiation rotation speed are raised. Alternatively, when the air conditioner compressor is active, the fuel injection stop rotation speed, or the fuel injection stop rotation speed and the fuel injection reinitiation speed, or the fuel injection reinitiation rotation speed are raised and the stop of the fuel injection is suppressed when the engine rotation speed is between the raised fuel injection stop rotation speed and the raised fuel injection reinitiation rotation speed. As a result, smooth feeling of deceleration is attained when the air conditioner compressor is active and the drivability is improved.
