摘要： In a method of permitting an electronic control device 10A that is a fuel injection control device constituting a part of a fuel injection system of an engine 1 to generate a fuel injection signal depending on an engine operation state while determining fuel injection timing by an engine rotation signal, and to output the signal to an injector 5, thereby controlling fuel injection of the engine, the electronic control unit 10A continuously detects a supply voltage thereto, and recognizes starting of rotation of the engine 1 when it is detected that a predetermined fluctuation has occurred in the supply voltage at the time of starting or when it is determined that the supply voltage at the time of starting is below a predetermined reference voltage value, and starts fuel injection even before input of the engine rotation signal.

摘要： In a fuel injection control method of an engine, an electronic control unit calculates a pressure integrated value for one combustion cycle by detecting a combustion cycle and continuously detecting a suction air pipe pressure and determines that the engine is under an accelerated state such that a pressure difference determined by comparing the pressure integrated value with the pressure integrated value at the preceding combustion cycle becomes equal to or more than a predetermined acceleration determining reference value, thereby increasing a fuel amount. The electronic control unit determines that the engine is under the accelerated state at a particular time when the difference between the pressure integrated value and the atmospheric pressure becomes equal to or less than a reference value and a pressure difference integrated value obtained by integrating each of the pressure differences within an integrating period becomes equal to or more than another reference value.
